Input: What are the treatments for Hearing Loss ?

Output: Your doctor can recommend strategies to help reduce the effects of a hearing loss. Scientists are studying ways to develop new, more effective methods to treat and prevent hearing loss. Hearing Aids A hearing aid is a small electronic device that you wear in or behind your ear. It makes some sounds louder so that a person with hearing loss can listen, communicate, and participate more fully in daily activities. A hearing aid can help people hear more in both quiet and noisy situations. However, only about one out of five people who would benefit from a hearing aid actually uses one. A hearing aid has three basic parts: a microphone, amplifier, and speaker. The hearing aid receives sound through a microphone, which converts the sound waves to electrical signals and sends them to an amplifier. The amplifier increases the power of the signals and then sends them to the ear through a speaker. Types of Hearing Aids There are a number of different types of hearing aids to treat different kinds of hearing loss. Choosing one will depend on the kind of hearing loss you have, you lifestyle, and your own preferences. - Behind-the-ear (BTE) hearing aids consist of a hard plastic case worn behind the ear and connected to a plastic earmold that fits inside the outer ear. The electronic parts are held in the case behind the ear. Sound travels from the hearing aid through the earmold and into the ear. BTE aids are used by people of all ages for mild to profound hearing loss.

BTE aids are used by people of all ages for mild to profound hearing loss. - Open-fit hearing aids fit completely behind the ear with only a narrow tube inserted into the ear canal. This lets the ear canal remain open. Open-fit hearing aids may be a good choice for people with a buildup of earwax since this type of aid is less likely to be damaged by earwax. Some people may prefer the open-fit hearing aid because they do not perceive their voice as sounding plugged up.

The case holding the electronic components is made of hard plastic. Some in-the-ear hearing aids may also use a telecoil, which is a small magnetic coil that allows you to receive sound through the circuitry of the hearing aid, rather than through the microphone. You can use the telecoil when you use the telephone and when you are in public places that have installed induction loop systems, such as churches, schools, airports, and auditoriums.

The in-the-canal hearing aid is made to fit the size and shape of your ear canal. A completely-in-canal hearing aid is nearly hidden in the ear canal. Both types are used for mild to moderately severe hearing loss. Because they are small, canal aids may be difficult for a person to adjust and remove. In addition, canal aids have less space available for batteries and additional devices, such as a telecoil. They usually are not recommended for people with severe to profound hearing loss because their reduced size limits their power and volume.

An audiologist or hearing aid specialist can help you determine if a hearing aid, or even two hearing aids, is the right treatment for you. Wearing two hearing aids may help balance sounds, improve your understanding of words in noisy situations, and make it easier to locate the source of sounds. Cochlear Implants If your hearing loss is severe and of a certain type, your doctor may suggest that you talk to an otolaryngologista surgeon who specializes in ear, nose, and throat diseasesabout a cochlear implant. A cochlear implant is a small electronic device that the surgeon places under the skin and behind the ear. The device picks up sounds, changes them to electrical signals, and sends them past the non-working part of the inner ear and on to the brain. A cochlear implant does not restore or create normal hearing. Instead, it can help people who are deaf or who have a severe hearing loss be more aware of their surroundings and understand speech, sometimes well enough to use the telephone. Learning to interpret sounds from the implant takes time and practice. A speech-language pathologist and audiologist can help you with this part of the process. Assistive Listening Devices Assistive listening devices devices can help you hear in certain listening environments. These can include telephone and cell phone amplifying devices, smart phone or tablet "apps," and closed circuit systems (induction coil loops) in places of worship, theaters, and auditoriums. TV listening systems help you listen to the television or the radio without being bothered by other noises around you. Some hearing aids can be plugged into televisions or stereos to help you hear better. New and Improved Treatments Under Study Researchers are studying the causes of hearing loss as well as new treatments. For example, they are studying ways to improve hearing aids so that wearers can hear certain sounds more clearly even when a person is surrounded by background noise. They are also studying how to improve cochlear implants to enhance a person's ability to understand sounds. And they are conducting a study on twins aged 50 and over to determine the extent to which age-related hearing loss runs in families. </s>


Input: How many people are affected by Hearing Loss ?

Output: Approximately 17 percent, or 36 million, of American adults say that they have some degree of hearing loss. Hearing loss is a common condition in older adults. Roughly one-third of Americans 65 to 74 years of age and 47 percent of those 75 and older have hearing loss. </s>


Input: What is (are) Hearing Loss ?

Output: Presbycusis is common in older adults. Presbycusis comes on gradually as a person ages and mostly affects people over 50. Doctors do not know why presbycusis happens, but it seems to run in families. Presbycusis may make it hard for a person to tolerate loud sounds or to hear what others are saying. This type of hearing loss involves damage to the inner ear and is permanent. Tinnitus, also common in older people, is the ringing, roaring, clicking, hissing, or buzzing sound in the ears frequently caused by presbycusis, exposure to loud noise or certain medications. Tinnitus can accompany any type of hearing loss. It also can be a sign of other important health problems, too, such as allergies and problems in the heart and blood vessels. Tinnitus may come and go, or stop altogether. </s>


Input: What causes Hearing Loss ?

Output: Hearing loss can result from taking certain medications. "Ototoxic" medications damage the inner ear, sometimes permanently. Check with your doctor if you notice a problem while taking a medication. </s>


Input: How to prevent Hearing Loss ?

Output: Washing your hands frequently can help prevent upper respiratory infections, which can lead to an ear infection called otitis media. The ear infection otitis media can be a cause of long-term hearing loss. Also, ask your doctor about a yearly flu shot to help prevent flu-related ear infections. If you still get an ear infection, see a doctor immediately before it becomes more serious. </s>

Input: What is (are) Parkinson's Disease ?

Output: A Brain Disorder Parkinson's disease is a brain disorder that leads to shaking, stiffness, and difficulty with walking, balance, and coordination. It affects about half a million people in the United States although the numbers may be much higher. The average age of onset is 60 years, and the risk of developing Parkinson's goes up with age. Parkinson's disease was first described in 1817 by James Parkinson, a British doctor who published a paper on what he called "the shaking palsy." In this paper, he described the major symptoms of the disease that would later bear his name. Four Main Symptoms Parkinson's disease belongs to a group of neurological conditions called movement disorders. The four main symptoms of Parkinson's are: - tremor, or trembling in hands, arms, legs, jaw, or head  - rigidity, or stiffness of the limbs and trunk  - bradykinesia, or slowness of movement  - postural instability, or impaired balance. tremor, or trembling in hands, arms, legs, jaw, or head rigidity, or stiffness of the limbs and trunk bradykinesia, or slowness of movement postural instability, or impaired balance. Parkinson's symptoms usually begin gradually and get worse over time. As the symptoms become more severe, people with the disorder may have difficulty walking, talking, or completing other simple tasks. They also experience non-motor, or movement, symptoms including mental and behavioral changes, sleep problems, depression, memory difficulties, and fatigue. Parkinson's disease not only affects the brain, but the entire body. While the brain involvement is responsible for the core features, other affected locations contribute to the complicated picture of Parkinson's. Parkinson's disease is both chronic, meaning it lasts for a long time, and progressive, meaning its symptoms grow worse over time. It is not contagious. Diagnosis Can Be Difficult About 60,000 Americans are diagnosed with Parkinson's disease each year. However, it's difficult to know exactly how many have it because many people in the early stages of the disease think their symptoms are due to normal aging and do not seek help from a doctor. Also, diagnosis is sometimes difficult because there are no medical tests that can diagnose the disease with certainty and because other conditions may produce symptoms of Parkinson's. For example, people with Parkinson's may sometimes be told by their doctors that they have other disorders, and people with diseases similar to Parkinson's may be incorrectly diagnosed as having Parkinson's. A persons good response to the drug levodopa may support the diagnosis. Levodopa is the main therapy for Parkinsons disease. Who Is at Risk? Both men and women can have Parkinsons disease. However, the disease affects about 50 percent more men than women. While the disease is more common in developed countries, studies also have found an increased risk of Parkinson's disease in people who live in rural areas and in those who work in certain professions, suggesting that environmental factors may play a role in the disorder. Researchers are focusing on additional risk factors for Parkinsons disease. One clear risk factor for Parkinson's is age. The average age of onset is 60 years and the risk rises significantly with advancing age. However, about 5 to 10 percent of people with Parkinson's have "early-onset" disease which begins before the age of 50. Early-onset forms of Parkinson's are often inherited, though not always, and some have been linked to specific gene mutations. Juvenile Parkinsonism In very rare cases, parkinsonian symptoms may appear in people before the age of 20. This condition is called juvenile parkinsonism. It is most commonly seen in Japan but has been found in other countries as well. It usually begins with dystonia (sustained muscle contractions causing twisting movements) and bradykinesia (slowness of movement), and the symptoms often improve with levodopa medication. Juvenile parkinsonism often runs in families and is sometimes linked to a mutated gene. Some Cases Are Inherited Evidence suggests that, in some cases, Parkinsons disease may be inherited. An estimated 15 to 25 percent of people with Parkinson's have a known relative with the disease. People with one or more close relatives who have Parkinson's have an increased risk of developing the disease themselves, but the total risk is still just 2 to 5 percent unless the family has a known gene mutation for the disease. A gene mutation is a change or alteration in the DNA or genetic material that makes up a gene. Researchers have discovered several genes that are linked to Parkinson's disease. The first to be identified was alpha-synuclein or SNCA. Inherited cases of Parkinsons disease are caused by mutations in the LRRK2, PARK2 or parkin, PARK7 or DJ-1, PINK1, or SNCA genes, or by mutations in genes that have not yet been identified. </s>


Input: What causes Parkinson's Disease ?

Output: A Shortage of Dopamine Parkinson's disease occurs when nerve cells, or neurons, in an area of the brain that controls movement become impaired and/or die. Normally, these neurons produce an important brain chemical known as dopamine, but when the neurons die or become impaired, they produce less dopamine. This shortage of dopamine causes the movement problems of people with Parkinson's. Dopamine is a chemical messenger, or neurotransmitter. Dopamine is responsible for transmitting signals between the substantia nigra and multiple brain regions. The connection between the substantia nigra and the corpus striatum is critical to produce smooth, purposeful movement. Loss of dopamine in this circuit results in abnormal nerve-firing patterns within the brain that cause impaired movement. Loss of Norepinephrine People with Parkinson's also have loss of the nerve endings that produce the neurotransmitter norepinephrine. Norepinephrine, which is closely related to dopamine, is the main chemical messenger of the sympathetic nervous system. The sympathetic nervous system controls many automatic functions of the body, such as heart rate and blood pressure. The loss of norepinephrine might help explain several of the non-movement features of Parkinson's, such as fatigue, irregular blood pressure, decreased gastric motility or movement of food through the digestive tract, and postural hypotension. Postural hypotension is a sudden drop in blood pressure when a person stands up from a sitting or lying-down position. It may cause dizziness, lightheadedness, and in some cases, loss of balance or fainting. Lewy Bodies in Brain Cells Many brain cells of people with Parkinson's contain Lewy bodies. Lewy bodies are unusual deposits or clumps of the brain protein alpha-synuclein, along with other proteins, which are seen upon microscopic examination of the brain. Researchers do not yet know why Lewy bodies form or what role they play in the development of Parkinson's. The clumps may prevent the cell from functioning normally, or they may actually be helpful, perhaps by keeping harmful proteins "locked up" so the cells can function. Genetic Mutations Although some cases of Parkinson's appear to be hereditary, and a few can be traced to specific genetic mutations, most cases are sporadic. Sporadic means the disease occurs randomly and does not seem to run in families. Many researchers now believe that Parkinson's disease results from a combination of genetic and environmental factors. Scientists have identified several genetic mutations associated with Parkinson's including mutations in the alpha-synuclein gene. They think that many more genes may be linked to the disorder. Studying the genes responsible for inherited cases of Parkinson's can help researchers understand both inherited and sporadic cases. The same genes and proteins that are altered in inherited cases may also be altered in sporadic cases by environmental toxins or other factors. Researchers also hope that discovering genes will help identify new ways of treating Parkinson's. Environmental Toxins Although researchers increasingly recognize the importance of genetics in Parkinson's disease, most believe environmental exposures increase a person's risk of developing the disease. Even in inherited cases, exposure to toxins or other environmental factors may influence when symptoms of the disease appear or how the disease progresses. There are a number of toxins that can cause parkinsonian symptoms in humans. Researchers are pursuing the question of whether pesticides and other environmental factors not yet identified also may cause Parkinson's disease. Viruses are another possible environmental trigger for Parkinson's. Mitochondria and Free Radicals Research suggests that mitochondria may play a role in the development of Parkinson's disease. Mitochondria are the energy-producing components of the cell and are major sources of free radicals. Free radicals are molecules that damage membranes, proteins, DNA, and other parts of the cell. This damage is called oxidative stress. Changes to brain cells caused by oxidative stress, including free radical damage to DNA, proteins, and fats, have been found in people with Parkinson's. Clinical studies now underway test whether agents thought to improve energy metabolism and decrease oxidative stress slow the progression of Parkinson's disease. Recent evidence suggests that mutations in genes linked to Parkinsons disease result in mitochondrial dysfunction. Buildup of Harmful Proteins Other research suggests that the cell's protein disposal system may fail in people with Parkinson's, causing proteins like alpha-synuclein to build up to harmful levels and trigger premature cell death. Additional studies have found that clumps of protein that develop inside brain cells of people with Parkinson's may contribute to the death of nerve cells, or neurons. However, the exact role of the protein deposits remains unknown. These studies also found that inflammation, because of protein accumulation, toxins or other factors, may play a role in the disease. However, the exact role of the protein deposits remains unknown. Researchers are exploring the possibility of vaccine development to decrease or prevent the accumulation of alpha-synuclein. While mitochondrial dysfunction, oxidative stress, inflammation, and many other cellular processes may contribute to Parkinson's disease, scientists still do not know what causes cells that produce dopamine to die. Genes Linked to Parkinsons Researchers have discovered several genes that are linked to Parkinson's disease. The first to be identified was alpha-synuclein or SNCA . Studies have found that Lewy bodies from people with the sporadic form of Parkinson's contain clumps of alpha-synuclein protein. This discovery revealed a possible link between hereditary and sporadic forms of the disease. Other genes linked to Parkinson's include PARK2, PARK7, PINK1, and LRRK2. PARK2, PARK7, and PINK1 cause rare, early-onset forms of the disease. Mutations in the LRRK2 gene are common in specific populations, including in people with Parkinson's in North Africa. Researchers are continuing to study the normal functions and interactions of these genes in order to find clues about how Parkinson's develops. They also have identified a number of other genes and chromosome regions that may play a role in Parkinson's, but the nature of these links is not yet clear. Whole genome wide association studies, or GWAS, of thousands of people with Parkinson's disease are now underway to find gene variants that allow for an increased risk of developing Parkinson's but are not necessarily causes of this disorder by themselves. A recent international study found that two genes containing mutations known to cause rare hereditary forms of Parkinsons disease are also associated with the more common sporadic form of the disease. This finding came from a GWAS which looked at DNA samples of European people who had Parkinsons disease and from those who did not have the disorder. </s>


Input: What are the symptoms of Parkinson's Disease ?

Output: Parkinson's disease does not affect everyone the same way. Symptoms of the disorder and the rate of progression differ among people with the disease. Sometimes people dismiss early symptoms of Parkinson's as the effects of normal aging. There are no medical tests to definitively diagnose the disease, so it can be difficult to diagnose accurately. Early Symptoms Early symptoms of Parkinson's disease are subtle and occur gradually. For example, affected people may feel mild tremors or have difficulty getting out of a chair. They may notice that they speak too softly or that their handwriting is slow and looks cramped or small. This very early period may last a long time before the more classic and obvious symptoms appear. Friends or family members may be the first to notice changes in someone with early Parkinson's. They may see that the person's face lacks expression and animation, a condition known as "masked face," or that the person does not move an arm or leg normally. They also may notice that the person seems stiff, unsteady, or unusually slow. As the Disease Progresses As the disease progresses, symptoms may begin to interfere with daily activities. The shaking or tremor may make it difficult to hold utensils steady or read a newspaper. Tremor is usually the symptom that causes people to seek medical help. People with Parkinson's often develop a so-called parkinsonian gait that includes a tendency to lean forward, small quick steps as if hurrying forward (called festination), and reduced swinging of the arms. They also may have trouble initiating or continuing movement, which is known as freezing. Symptoms often begin on one side of the body or even in one limb on one side of the body. As the disease progresses, it eventually affects both sides. However, the symptoms may still be more severe on one side than on the other. Four Primary Symptoms The four primary symptoms of Parkinson's are tremor, rigidity, slowness of movement (bradykinesia), and impaired balance (postural instability). - Tremor often begins in a hand, although sometimes a foot or the jaw is affected first. It is most obvious when the hand is at rest or when a person is under stress. It usually disappears during sleep or improves with a deliberate movement.   - Rigidity, or a resistance to movement, affects most people with Parkinson's. It becomes obvious when another person tries to move the individual's arm, such as during a neurological examination. The arm will move only in ratchet-like or short, jerky movements known as "cogwheel" rigidity.   - Bradykinesia, or the slowing down and loss of spontaneous and automatic movement, is particularly frustrating because it may make simple tasks somewhat difficult. Activities once performed quickly and easily, such as washing or dressing, may take several hours.   - Postural instability, or impaired balance, causes people with Parkinson's to fall easily. They also may develop a stooped posture with a bowed head and droopy shoulders.  Tremor often begins in a hand, although sometimes a foot or the jaw is affected first.

Many can be treated with medication or physical therapy. No one can predict which symptoms will affect an individual person, and the intensity of the symptoms varies from person to person. Many people note that prior to experiencing motor problems of stiffness and tremor, they had symptoms of a sleep disorder, constipation, decreased ability to smell, and restless legs. Other symptoms include - depression  - emotional changes  - difficulty swallowing and chewing  - speech changes  - urinary problems or constipation  - skin problems, sleep problems  - dementia or other cognitive problems  - orthostatic hypotension (a sudden drop in blood pressure when standing up from a sitting or lying down position)  - muscle cramps and dystonia (twisting and repetitive movements)  - pain  - fatigue and loss of energy  - sexual dysfunction. depression emotional changes difficulty swallowing and chewing speech changes urinary problems or constipation skin problems, sleep problems dementia or other cognitive problems orthostatic hypotension (a sudden drop in blood pressure when standing up from a sitting or lying down position) muscle cramps and dystonia (twisting and repetitive movements) pain fatigue and loss of energy sexual dysfunction. A number of disorders can cause symptoms similar to those of Parkinson's disease. People with Parkinson's-like symptoms that result from other causes are sometimes said to have parkinsonism. While these disorders initially may be misdiagnosed as Parkinson's, certain medical tests, as well as response to drug treatment, may help to distinguish them from Parkinson's. Diagnosis Can Be Difficult There are currently no blood, or laboratory tests to diagnose sporadic Parkinson's disease. Diagnosis is based on a person's medical history and a neurological examination, but the disease can be difficult to diagnose accurately. Early signs and symptoms of Parkinson's may sometimes be dismissed as the effects of normal aging. A doctor may need to observe the person for some time until it is clear that the symptoms are consistently present. Improvement after initiating medication is another important hallmark of Parkinson's disease. Doctors may sometimes request brain scans or laboratory tests to rule out other diseases. However, computed tomography (CT) and magnetic resonance imaging (MRI) brain scans of people with Parkinson's usually appear normal. Recently, the FDA (Food and Drug Administration) has approved an imaging technique called DaTscan, which may help to increase accuracy of the diagnosis of Parkinsons disease. Since many other diseases have similar features but require different treatments, it is very important to make an exact diagnosis as soon as possible to ensure proper treatment. </s>


Input: What are the treatments for Parkinson's Disease ?

Output: Deep Brain Stimulation Deep brain stimulation, or DBS, is a surgical procedure used to treat a variety of disabling disorders. It is most commonly used to treat the debilitating symptoms of Parkinsons disease. Deep brain stimulation uses an electrode surgically implanted into part of the brain. The electrodes are connected by a wire under the skin to a small electrical device called a pulse generator that is implanted in the chest. The pulse generator and electrodes painlessly stimulate the brain in a way that helps to stop many of the symptoms of Parkinson's such as tremor, bradykinesia, and rigidity. DBS is primarily used to stimulate one of three brain regions: the subthalamic nucleus, the globus pallidus, or the thalamus. Researchers are exploring optimal generator settings for DBS, whether DBS of other brain regions will also improve symptoms of Parkinsons disease, and also whether DBS may slow disease progression. Deep brain stimulation usually reduces the need for levodopa and related drugs, which in turn decreases dyskinesias and other side effects. It also helps to relieve on-off fluctuation of symptoms. People who respond well to treatment with levodopa tend to respond well to DBS. Unfortunately, older people who have only a partial response to levodopa may not improve with DBS. Complementary and Supportive Therapies A wide variety of complementary and supportive therapies may be used for Parkinson's disease. Among these therapies are standard physical, occupational, and speech therapies, which help with gait and voice disorders, tremors and rigidity, and decline in mental functions. Other supportive therapies include diet and exercise. Diet At this time there are no specific vitamins, minerals, or other nutrients that have any proven therapeutic value in Parkinson's disease. Some early reports have suggested that dietary supplements might protect against Parkinson's. Also, a preliminary clinical study of a supplement called coenzyme Q10 suggested that large doses of this substance might slow disease progression in people with early-stage Parkinson's. This supplement is now being tested in a large clinical trial. Other studies are being conducted to find out if caffeine, antioxidants, nicotine, and other dietary factors may help prevent or treat the disease. While there is currently no proof that any specific dietary factor is beneficial, a normal, healthy diet can promote overall well-being for people with Parkinson's disease, just as it would for anyone else. A high protein meal, however, may limit levodopa's effectiveness because for a time afterwards less levodopa passes through the blood-brain barrier. Exercise Exercise can help people with Parkinson's improve their mobility and flexibility. It can also improve their emotional well-being. Exercise may improve the brain's dopamine production or increase levels of beneficial compounds called neurotrophic factors in the brain. Other Therapies Other complementary therapies include massage therapy, yoga, tai chi, hypnosis, acupuncture, and the Alexander technique, which improves posture and muscle activity. There have been limited studies suggesting mild benefits from some of these therapies, but they do not slow Parkinson's disease and to date there is no convincing evidence that they help. However, this remains an active area of investigation. </s>


Input: what research (or clinical trials) is being done for Parkinson's Disease ?

Output: In recent years, research on Parkinson's has advanced to the point that halting the progression of the disease, restoring lost function, and even preventing the disease are all considered realistic goals. While the goal of preventing Parkinson's disease may take years to achieve, researchers are making great progress in understanding and treating it. Genetics Research One of the most exciting areas of Parkinson's research is genetics. Studying the genes responsible for inherited cases can help researchers understand both inherited and sporadic cases of the disease. Identifying gene defects can also help researchers -  understand how Parkinson's occurs  -  develop animal models that accurately mimic the death of nerve cells in humans  - identify new approaches to drug therapy  - improve diagnosis.  understand how Parkinson's occurs develop animal models that accurately mimic the death of nerve cells in humans identify new approaches to drug therapy improve diagnosis. Researchers funded by the National Institute of Neurological Disorders and Stroke are gathering information and DNA samples from hundreds of families with members who have Parkinson's and are conducting large-scale studies to identify gene variants that are associated with increased risk of developing the disease. They are also comparing gene activity in Parkinson's with gene activity in similar diseases such as progressive supranuclear palsy. In addition to identifying new genes for Parkinson's disease, researchers are trying to learn about the function of genes known to be associated with the disease, and about how gene mutations cause disease. Effects of Environmental Toxins Scientists continue to study environmental toxins such as pesticides and herbicides that can cause Parkinson's symptoms in animals. They have found that exposing rodents to the pesticide rotenone and several other agricultural chemicals can cause cellular and behavioral changes that mimic those seen in Parkinson's. Role of Lewy Bodies Other studies focus on how Lewy bodies form and what role they play in Parkinson's disease. Some studies suggest that Lewy bodies are a byproduct of a breakdown that occurs within nerve cells, while others indicate that Lewy bodies are protective, helping neurons "lock away" abnormal molecules that might otherwise be harmful. Identifying Biomarkers Biomarkers for Parkinson's -- measurable characteristics that can reveal whether the disease is developing or progressing -- are another focus of research. Such biomarkers could help doctors detect the disease before symptoms appear and improve diagnosis of the disease. They also would show if medications and other types of therapy have a positive or negative effect on the course of the disease. The National Disorders of Neurological Disorders and Stroke has developed an initiative, the Parkinsons Disease Biomarkers Identification Network (PD-BIN), designed specifically to address these questions and to discover and validate biomarkers for Parkinsons disease. Transcranial Therapies Researchers are conducting many studies of new or improved therapies for Parkinson's disease. Studies are testing whether transcranial electrical polarization (TEP) or transcranial magnetic stimulation (TMS) can reduce the symptoms of the disease. In TEP, electrodes placed on the scalp are used to generate an electrical current that modifies signals in the brain's cortex. In TMS, an insulated coil of wire on the scalp is used to generate a brief electrical current. Drug Discovery A variety of new drug treatments for Parkinson's disease are in clinical trials. Several MAO-B inhibitors including selegiline, lazabemide, and rasagiline, are being tested to determine if they have neuroprotective effects in people with Parkinsons disease. The National Institute of Neurological Disorders and Stroke has launched a broad effort to find drugs to slow the progression of Parkinson's disease, called NET-PD or NIH Exploratory Trials in Parkinson's Disease. The first studies tested several compounds; one of these, creatine, is now being evaluated in a larger clinical trial. The NET-PD investigators are testing a highly purified form of creatine, a nutritional supplement, to find out if it slows the decline seen in people with Parkinson's. Creatine is a widely used dietary supplement thought to improve exercise performance. Cellular energy is stored in a chemical bond between creatine and a phosphate. More recently, NET-PD has initiated pilot studies to test pioglitazone, a drug that has been shown to stimulate mitochondrial function. Because mitochondrial function may be less active in Parkinsons disease, this drug may protect vulnerable dopamine neurons by boosting mitochondrial function. Cell Implantation Another potential approach to treating Parkinson's disease is to implant cells to replace those lost in the disease. Starting in the 1990s, researchers conducting a controlled clinical trial of fetal tissue implants tried to replace lost dopamine-producing nerve cells with healthy ones from fetal tissue in order to improve movement and the response to medications. While many of the implanted cells survived in the brain and produced dopamine, this therapy was associated with only modest functional improvements, mostly in patients under the age of 60. Some of the people who received the transplants developed disabling dyskinesias that could not be relieved by reducing anti-parkinsonian medications. Stem Cells Another type of cell therapy involves stem cells. Some stem cells derived from embryos can develop into any kind of cell in the body, while others, called progenitor cells, are less flexible. Researchers are developing methods to improve the number of dopamine-producing cells that can be grown from embryonic stem cells in culture. Other researchers are also exploring whether stem cells from adult brains might be useful in treating Parkinson's disease. Recent studies suggest that some adult cells from skin can be reprogrammed to an embryonic-like state, resulting in induced pluripotent stem cells (iPSC) that may someday be used for treatment of Parkinsons. In addition, development and characterization of cells from people with sporadic or inherited Parkinsons may reveal information about cellular mechanisms of disease and identify targets for drug development. Gene Therapy A number of early clinical trials are now underway to test whether gene therapy can improve Parkinson's disease. Genes which are found to improve cellular function in models of Parkinson's are inserted into modified viruses. The genetically engineered viruses are then injected into the brains of people with Parkinson's disease. Clinical studies have focused on the therapeutic potential of neurotrophic factors, including GDNF and neurturin, and enzymes that produce dopamine. These trials will test whether the viruses, by lending to the production of the protective gene product, improve symptoms of Parkinson's over time. The National Institute of Neurological Disorders and Stroke also supports the Morris K. Udall Centers of Excellence for Parkinson's Disease Research program . These Centers, located across the USA, study cellular mechanisms underlying Parkinsons disease, identify and characterize disease-associated genes, and discover and develop potential therapeutic targets. The Centers' multidisciplinary research environment allows scientists to take advantage of new discoveries in the basic, translational and clinical sciences that could lead to clinical advances for Parkinsons disease. </s>


Input: What is (are) Parkinson's Disease ?

Output: Parkinson's disease is a brain disorder that leads to shaking, stiffness, and difficulty with walking, balance, and coordination. It currently affects about half a million people in the United States, although the numbers may be much higher. Parkinson's disease is both chronic, meaning it lasts for a long time, and progressive, meaning its symptoms grow worse over time. It is not contagious. </s>


Input: What are the symptoms of Parkinson's Disease ?

Output: Parkinson's belongs to a group of neurological conditions called movement disorders. The four main symptoms of Parkinson's disease are: - tremor, or trembling in hands, arms, legs, jaw, or head  - rigidity, or stiffness of the limbs and trunk  - bradykinesia, or slowness of movement  - postural instability, or impaired balance. tremor, or trembling in hands, arms, legs, jaw, or head rigidity, or stiffness of the limbs and trunk bradykinesia, or slowness of movement postural instability, or impaired balance. Other symptoms include depression, emotional changes, difficulty swallowing, speech changes, urinary problems, sleep problems, and dementia and other cognitive problems. Parkinson's symptoms usually begin gradually and get worse over time. As the symptoms become more severe, people with the disorder may have difficulty walking, talking, or completing other simple tasks. They also experience non-motor, or movement, symptoms including mental and behavioral changes, sleep problems, depression, memory difficulties, and fatigue. Parkinson's disease not only affects the brain, but the entire body. While the brain involvement is responsible for the core features, other affected locations contribute to the complicated picture of Parkinson's. </s>


Input: Who is at risk for Parkinson's Disease? ?

Output: About 60,000 Americans are diagnosed with Parkinson's disease each year. The disease strikes about 50 percent more men than women. The average age of onset is 60 years, and the risk of developing the disease increases with age. Parkinson's disease is also more common in developed countries, possibly because of increased exposure to pesticides or other environmental toxins. </s>


Input: What causes Parkinson's Disease ?

Output: Parkinson's disease occurs when nerve cells, or neurons, in an area of the brain that controls movement die or become impaired. Normally, these neurons produce an important brain chemical known as dopamine, but once the neurons become impaired, they produce less dopamine and eventually die. It is this shortage of dopamine that causes the movement problems of people with Parkinson's. </s>


Input: What is (are) Parkinson's Disease ?

Output: Dopamine is a brain chemical messenger, or neurotransmitter. It is responsible for transmitting signals between a brain region called the substantia nigra and multiple brain regions. The connection between the substantia nigra and the corpus striatum is critical to produce smooth, purposeful movement. Loss of dopamine results in abnormal nerve-firing patterns within the brain that cause impaired movement. </s>


Input: What is (are) Parkinson's Disease ?

Output: Lewy bodies are unusual deposits or clumps of the brain protein alpha-synuclein, along with other proteins, which are seen upon microscopic examination of the brain. Many brain cells of people with Parkinson's disease contain Lewy bodies. Researchers do not yet know why Lewy bodies form or what role they play in the development of Parkinson's disease. The clumps may prevent the cell from functioning normally, or they may actually be helpful, perhaps by keeping harmful proteins "locked up" so that the cells can function. </s>


Input: How to diagnose Parkinson's Disease ?

Output: There are currently no blood or laboratory tests to diagnose sporadic Parkinson's disease. Diagnosis is based on a person's medical history and a neurological examination, but the disease can be difficult to diagnose accurately. Doctors may sometimes request brain scans or laboratory tests in order to rule out other diseases. However, computed tomography (CT) and magnetic resonance imaging (MRI) brain scans of people with Parkinson's usually appear normal. Recently, the FDA (Food and Drug Administration) has approved an imaging technique called DaTscan, which may help to increase accuracy of the diagnosis of Parkinsons disease. Since many other diseases have similar features but require different treatments, it is very important to make an exact diagnosis as soon as possible to ensure proper treatment. </s>


Input: What is (are) Parkinson's Disease ?

Output: The main therapy for Parkinson's disease is the drug levodopa, also called L-dopa. It is a simple chemical found naturally in plants and animals. Nerve cells use levodopa to make dopamine to replenish the brain's supply. Levodopa helps to reduce tremors and other symptoms of Parkinson's disease during the early stages of the disease. It allows most people with Parkinson's to extend the period of time in which they can lead relatively normal, productive lives. </s>


Input: What is (are) Parkinson's Disease ?

Output: Carbidopa is a drug that is usually given along with levodopa. It delays the body's conversion of levodopa into dopamine until the levodopa reaches the brain. This prevents or reduces some of the side effects that often accompany levodopa therapy. Carbidopa also reduces the amount of levodopa needed. </s>


Input: What are the treatments for Parkinson's Disease ?

Output: Yes. Other medications available to treat some symptoms and stages of Parkinson's disease include direct dopamine agonists, MAO-B inhibitors, COMT inhibitors, an anti-viral drug, and anticholinergics. Direct dopamine agonists are drugs that mimic the role of dopamine in the brain. They can be used in the early stages of the disease, or later on to give a more prolonged and steady dopaminergic effect in people who experience "wearing off" or "on-off" effects from taking the drug. Dopamine agonists are generally less effective than levodopa in controlling rigidity and bradykinesia. They can cause confusion in older adults. MAO-B inhibitors are another class of drugs that can reduce the symptoms of Parkinson's by causing dopamine to build up in surviving nerve cells. COMT inhibitors prolong the effects of levodopa by preventing the breakdown of dopamine. COMT inhibitors can usually make it possible to reduce a person's dose of levodopa. Amantadine, an old antiviral drug, can help reduce Parkinson's symptoms in the early stages of the disease, and again in later stages to treat dyskinesias. Anticholinergics can help reduce tremors and muscle rigidity. </s>


Input: What are the symptoms of Parkinson's Disease ?

Output: Doctors may prescribe a variety of medications to treat the non-motor symptoms of Parkinson's disease, such as depression and anxiety. Hallucinations, delusions, and other psychotic symptoms may be caused by some drugs prescribed for Parkinson's. Therefore, reducing or stopping those Parkinson's medications may make these symptoms of psychosis go away. A variety of treatment options, including medications, also are available to treat orthostatic hypotension, the sudden drop in blood pressure that occurs upon standing. </s>


Input: What is (are) Parkinson's Disease ?

Output: Deep brain stimulation, or DBS, is a surgical procedure used to treat a variety of disabling disorders. It is most commonly used to treat the debilitating symptoms of Parkinsons disease. Deep brain stimulation uses an electrode surgically implanted into part of the brain. The electrodes are connected under the skin to a small electrical device called a pulse generator, implanted in the chest. The generator and electrodes painlessly stimulate the brain to help stop many Parkinson's symptoms such as tremor, bradykinesia, and rigidity. DBS is primarily used to stimulate one of three brain regions: the subthalamic nucleus, the globus pallidus, or the thalamus. Researchers are exploring optimal generator settings for DBS, whether DBS of other brain regions will also improve symptoms of Parkinsons disease, and also whether DBS may slow disease progression. Deep brain stimulation usually reduces the need for levodopa and related drugs, which in turn decreases dyskinesias and other side effects. It also helps to relieve "on-off" fluctuation of symptoms. People who respond well to treatment with levodopa, even if only for a short period, tend to respond well to DBS. </s>


Input: what research (or clinical trials) is being done for Parkinson's Disease ?

Output: Genetics is one of the most exciting areas of Parkinson's disease research. Studying the genes responsible for inherited cases can help researchers understand both inherited and sporadic cases of the disease. Sporadic means the disease occurs randomly and does not seem to run in families. Identifying gene defects can also help researchers - understand how the disease occurs   - develop animal models that accurately mimic the death of nerve cells in human Parkinson's disease  - identify new drug targets   - improve diagnosis. understand how the disease occurs develop animal models that accurately mimic the death of nerve cells in human Parkinson's disease identify new drug targets improve diagnosis. </s>

Input: What is (are) Problems with Smell ?

Output: Our sense of smell helps us enjoy life. We delight in the aromas of our favorite foods or the fragrance of flowers. Our sense of smell also is a warning system, alerting us to danger signals such as a gas leak, spoiled food, or a fire. Any loss in our sense of smell can have a negative effect on our quality of life. It also can be a sign of more serious health problems. Aging and Smell Loss Problems with smell increase as people get older, and they are more common in men than women. In one study, nearly one-quarter of men ages 6069 had a smell disorder, while about 11 percent of women in that age range reported a problem. Many older people are not even aware that they have a problem with their sense of smell because the changes occur gradually over several years. They may not even notice that they are experiencing a loss of smell until there is an incident in which they don't detect food that has spoiled or the presence of dangerous smoke. How Our Sense of Smell Works The sense of smell, or olfaction, is part of our chemical sensing system, along with the sense of taste. Normal smell occurs when odors around us, like the fragrance of flowers or the smell of baking bread, stimulate the specialized sensory cells, called olfactory sensory cells. Olfactory sensory cells are located in a small patch of tissue high inside the nose. Odors reach the olfactory sensory cells in two pathways. The first pathway is by inhaling, or sniffing, through your nose. When people think about smell, they generally think of this pathway. The second pathway is less familiar. It is a channel that connects the roof of the throat region to the nose. When we chew our food, aromas are released that access olfactory sensory cells through this channel. If you are congested due to a head cold or sinus infection, this channel is blocked, which temporarily affects your ability to appreciate the flavors of food. Types of Smell Disorders People who experience smell disorders either have a decrease in their ability to smell or changes in the way they perceive odors. Total smell loss is relatively rare, but a decrease in the sense of smell occurs more often, especially in older adults. A decreased sense of smell may be temporary and treatable with medication. There are several types of smell disorders depending on how the sense of smell is affected. -  Some people have hyposmia, which occurs when their ability to detect certain odors is reduced.   - Other people can't detect odor at all, which is called anosmia.   - Sometimes a loss of smell can be accompanied by a change in the perception of odors. This type of smell disorder is called dysosmia. Familiar odors may become distorted, or an odor that usually smells pleasant instead smells foul.   - Still others may perceive a smell that isn't present at all, which is called phantosmia.   - Smell loss due to aging is called presbyosmia.

Smell loss due to aging is called presbyosmia. Smell Loss May Signal Other Conditions Problems with our chemical senses may be a sign of other serious health conditions. A smell disorder can be an early sign of Parkinsons disease, Alzheimers disease, or multiple sclerosis. It can also be related to other medical conditions, such as obesity, diabetes, hypertension, and malnutrition. Getting a diagnosis early will help an individual deal better with the underlying condition or disease. Smell and Taste Smell and taste are closely linked in the brain, but are actually distinct sensory systems. True tastes are detected by taste buds on the tongue and the roof of the mouth, as well as in the throat region, and are limited to sweet, salty, sour, bitter, savory and perhaps a few other sensations. The loss of smell is much more common than the loss of taste, and many people mistakenly believe they have a problem with taste, when they are really experiencing a problem with their sense of smell. A loss in taste or smell is diagnosed by your doctor using special taste and smell tests. Smell Loss and Eating Habits When smell is impaired, people usually have problems appreciating the subtle flavors of food, and say that food is less enjoyable. Some people change their eating habits. Some may eat too little and lose weight while others may eat too much and gain weight. Either way, there may be a long-term impact on one's overall health. Loss of smell may also cause us to eat too much sugar or salt to make our food taste better. This can be a problem for people with certain medical conditions, such as diabetes or high blood pressure. In severe cases, loss of smell can lead to depression. Hazards of Smell Loss Research shows that people with a total or partial loss of smell are almost twice as likely as people with normal smell to have certain kinds of accidents. The most common types of accidents in order of frequency involve - cooking   - eating or drinking spoiled foods or toxic substances   - failing to detect gas leaks or fires  cooking eating or drinking spoiled foods or toxic substances failing to detect gas leaks or fires If you think you have a problem with your sense of smell, see your doctor. </s>


Input: What causes Problems with Smell ?

Output: Problems with smell happen for many reasons, some clearer than others. Loss of smell may be permanent or temporary, depending on the cause. Effects of Aging As with vision and hearing, people gradually lose their ability to smell as they get older. Smell that declines with age is called presbyosmia and is not preventable. Age is only one of the many reasons that problems with smell can occur. Most people who develop a problem with smell have recently had an illness or injury. Common Causes The common causes of smell disorders are -  sinus and upper respiratory infections   - aging   - smoking  - nasal polyps   - head injury   - allergies  - hormonal disturbances  - dental problems  - exposure to certain chemicals   - numerous medications   - radiation for treatment of head and neck cancers  - diseases of the nervous system. sinus and upper respiratory infections aging smoking nasal polyps head injury allergies hormonal disturbances dental problems exposure to certain chemicals numerous medications radiation for treatment of head and neck cancers diseases of the nervous system. Sinus and Upper Respiratory Infections. The most common causes of smell problems are the common cold and chronic nasal or sinus infection. Respiratory infections such as the flu can lead to smell disorders. Swollen sinuses and nasal passages often result in problems with smell because the odors in the air do not have good access to the olfactory sensory cells. These conditions may cause total or partial loss of smell. The problem usually diminishes or goes away when the underlying medical condition clears up. Aging. Problems with smell become more common as people get older. A person's sense of smell generally declines when he or she is over 60. Smoking. Tobacco smoking is the most concentrated form of pollution that most people are exposed to. It impairs the ability to identify and enjoy odors. Nasal Polyps. Loss of smell can be caused by nasal polyps, which are small, non-cancerous growths in the nose or sinuses that can block the ability of odors to reach olfactory sensory cells high up in the nose. In rare cases, benign non-malignant tumors grow on the olfactory nerves leading to the brain, causing a loss of smell. Previous surgery or trauma to the head can impair your sense of smell because the olfactory nerves may be cut, blocked, or physically damaged. Automobile accidents are among the most frequent causes of trauma to the face and head. Allergies. If your smell disorder is caused by allergies and seasonal nasal congestion, you should avoid allergens, such as ragweed, grasses, and pet dander. Exposure to Certain Chemicals. Sometimes exposure to certain chemicals, such as insecticides and solvents, can permanently damage the sense of smell. Medications.  If you are taking certain medicines, you may notice a change in your ability to smell. Certain medications, including some common antibiotics and antihistamines, can cause problems with smell. The sense of smell usually returns to normal when you stop taking the medicine. Radiation Treatment.  People with head and neck cancers who receive radiation treatment to the nose and mouth regions commonly experience problems with their sense of smell and taste as an unfortunate side effect. Older people who have lost their larynx or voice box commonly complain of poor ability to smell and taste. Diseases of the Nervous System. Sometimes a problem with smell can be a sign of a more serious health problem. This might include diseases of the nervous system, such as Parkinson's disease or Alzheimer's disease. Loss of smell may be the first sign that something is wrong. Check with your doctor if you've been experiencing a problem with your sense of smell for a while. You may be able to prevent or get early treatment for a more serious health problem. </s>


Input: What are the symptoms of Problems with Smell ?

Output: A Reduced Sense of Smell There are several types of smell disorders depending on how the sense of smell is affected. People who have smell disorders experience either a loss in their ability to smell or changes in the way they perceive odors. Some people have hyposmia, which occurs when their ability to detect certain odors is reduced. This smell disorder is common in people who have upper respiratory infections or nasal congestion. This is usually temporary and goes away when the infection clears up. If You Can't Detect Odor at All Other people can't detect odor at all, which is called anosmia. This type of smell disorder is sometimes the result of head trauma in the nose region, usually from an automobile accident or chronic nasal or sinus infections. It can sometimes be caused by aging. In rare cases, anosmia is inherited. If Your Sense of Smell Is Distorted Sometimes a loss of smell can be accompanied by a change in the perception of odors. This type of smell disorder is called dysosmia. Familiar odors may become distorted, or an odor that usually smells pleasant instead smells foul. Sometimes people with this type of smell disorder also experience headaches, dizziness, shortness of breath, or anxiety. Still others may perceive a smell that isn't present at all, which is called phantosmia. Questions To Ask Yourself If you think you have a problem with your sense of smell, try to identify and record the circumstances at the time you first noticed the problem. Ask yourself the following questions: - When did I first become aware of it?  - Did I have a cold or the flu?  - Did I have a head injury?  - Was I exposed to air pollutants, pollens, pet dander, or dust to which I might be allergic?   - Is this a recurring problem?   - Does it come at any special time, like during the hay fever season? When did I first become aware of it? Did I have a cold or the flu? Did I have a head injury? Was I exposed to air pollutants, pollens, pet dander, or dust to which I might be allergic? Is this a recurring problem? Does it come at any special time, like during the hay fever season? Bring this information with you when you visit your physician. Also, be prepared to tell him or her about your general health and any medications you are taking. Talking With Your Doctor Diagnosis by a doctor is important to identify and treat the underlying cause of a potential smell disorder. Your doctor may refer you to an otolaryngologist, a specialist in diseases of the ear, nose, and throat. An accurate assessment of a smell disorder will include, among other things, - a physical examination of the ears, nose, and throat   - a review of your health history, such as exposure to toxic chemicals or injury, and   - a smell test supervised by a health care professional. a physical examination of the ears, nose, and throat a review of your health history, such as exposure to toxic chemicals or injury, and a smell test supervised by a health care professional. Tests for Smell Disorders Some tests measure the smallest amount of odor you can detect. You also may receive a "scratch and sniff" test to determine how well you can identify various odors from a list of possibilities. In this test, the odor is embedded in a circular pad on a piece of paper and released when scratched. In this way, doctors can determine whether a person has a decreased ability to smell (hyposmia), the inability to detect any odors (anosmia), or another kind of smell disorder. In some cases, your doctor may need to perform a nasal examination with a nasal endoscope, an instrument that illuminates and magnifies the areas of the nose where the problem may exist. This test can help identify the area and extent of the problem and help your doctor select the right treatment. If your doctor suspects that upper regions of the nose and nasal sinuses that can't be seen by an endoscope are involved, he or she may order a specialized X-ray procedure, usually a CT scan, to look further into the nose and sinuses. When to See the Doctor If you think you have a smell disorder, see your doctor. Diagnosis of a smell disorder is important because once the cause is found, your doctor may be able to treat your smell disorder. Many types of smell problems are reversible, but if they are not, counseling and self-help techniques may help you cope. </s>


Input: What are the treatments for Problems with Smell ?

Output: Relief is Possible Although there is no treatment for presbyosmia -- loss of smell due to aging -- relief from smell disorders is possible for many older people. Depending on the cause of your problem with smell, your doctor may be able to treat it or suggest ways to cope with it. Recovering the Ability To Smell Some people recover their ability to smell when they recover from the illness causing their loss of smell. Some people recover their sense of smell spontaneously, for no obvious reason. Other common causes of smell loss, such as the common cold or seasonal allergies, are usually temporary. Smell is regained by waiting for the illness to run its course. In some cases, nasal obstructions, such as polyps, can be removed to restore airflow through the nasal passages and restore the sense of smell. If your smell disorder cant be successfully treated, you might want to seek counseling to help you adjust. Ask About Your Medications Sometimes a certain medication causes a smell disorder, and improvement occurs when the medicine causing the problem is stopped or changed. If you take medications, ask your doctor if they can affect your sense of smell. If so, ask if you could substitute other medications or reduce the dose. Your doctor will work with you to get the medicine you need while trying to reduce unwanted side effects. Medications That May Help Your doctor may suggest oral steroid medications such as prednisone, which is usually used for a short period of time, or topical steroid sprays, which can be used for longer periods of time. Antibiotics are also used to treat nasal infections. The effectiveness of both steroids and antibiotics depends greatly on the severity and duration of the nasal swelling or infection. Often relief is temporary. Occasionally, the sense of smell returns to normal on its own without any treatment. Steps You Can Take If you have a problem with smell, there are some things you can do. - Wait it out. If you have had a cold with a stuffy nose, chances are in a few days your sense of smell will return. However, you should not wait to see your doctor if you think something more serious has caused your loss of smell or you have had the problem for a while. Loss of smell can sometimes mean a more serious condition exists.  Wait it out. If you have had a cold with a stuffy nose, chances are in a few days your sense of smell will return.

If Your Smell Loss Is Permanent If you do not regain your sense of smell, there are things you should do to ensure your safety. Take extra precautions to avoid eating food that may have spoiled. If you live with other people, ask them to smell the food to make sure it is fresh. People who live alone should discard food if there is a chance it is spoiled. Other home safety measures include installing smoke alarms and gas detectors. For those who wish to have additional help, there may be support groups in your area. These are often associated with smell and taste clinics in medical school hospitals. Some online bulletin boards also allow people with smell disorders to share their experiences. Not all people with smell disorders will regain their sense of smell, but most can learn to live with it.

Input: What causes Problems with Smell ?

Output: In rare cases, certain medicines such as antibiotics or antihistamines may cause a change in your ability to smell. If you are taking these medications and notice a change in your sense of smell, talk to your doctor. You may be able to adjust or change your medicine to one that will not cause a problem with smell. </s>


Input: How to diagnose Problems with Smell ?

Output: Scientists have developed tests to determine the nature and extent of a person's smell disorder. Tests measure the smallest amount of odor patients can detect as well as how accurately a person can identify different smells. An easily administered "scratch and sniff" test allows a person to scratch pieces of paper treated to release different odors, sniff them, and try to identify each odor from a list of possibilities. In this way, doctors can determine whether a person has a decreased ability to smell (hyposmia), the inability to detect any odors (anosmia), or another kind of smell disorder. In some cases, your doctor may need to perform a nasal examination with a nasal endoscope, an instrument that illuminates and magnifies the areas of the nose where the problem may exist. This test can help identify the area and extent of the problem and help your doctor select the right treatment. If your doctor suspects that upper regions of the nose and nasal sinuses that can't be seen by an endoscope are involved, he or she may order a specialized X-ray procedure, usually a CT scan, to look further into the nose and sinuses. </s>


Input: What are the treatments for Problems with Smell ?

Output: Depending on the cause of your smell disorder, your doctor may be able to treat your problem or suggest ways to cope with it. If a certain medication is the cause of the disorder, ask your doctor if you could substitute other medications or reduce the dose. Your doctor will work with you to get the medicine you need while trying to reduce unwanted side effects. Some patients with respiratory infections or allergies regain their sense of smell when the illness or condition is over. Often, correcting a general medical problem also can restore the sense of smell. For patients with nasal obstructions, such as polyps, or other inflammatory conditions of the nose or sinuses, medical treatments or surgery can restore the sense of smell. Occasionally, the sense of smell returns to normal on its own, without any treatment. Your doctor may suggest oral steroid medications such as prednisone, which is usually used for a short period of time, or topical steroid sprays, which can be used for longer periods of time. Antibiotics are also used to treat nasal infections. The effectiveness of both steroids and antibiotics depends greatly on the severity and duration of the nasal swelling or infection. Often relief is temporary. </s>

Input: How to diagnose Alzheimer's Caregiving ?

Output: Now that your family member or friend has received a diagnosis of Alzheimers disease, its important to learn as much as you can about the disease and how to care for someone who has it. You may also want to know the right way to share the news with family and friends. Learning About Alzheimers Sometimes, you may feel that you don't know how to care for the person with Alzheimers. This is a common feeling among caregivers of people with Alzheimers because each day may bring different challenges. Learning about the disease can help you understand and cope with these challenges. Here is some information about Alzheimers and ways you can learn more about it. Alzheimers disease is an illness of the brain. It causes large numbers of nerve cells in the brain to die. This affects a persons ability to remember things and think clearly. People with Alzheimers become forgetful and easily confused and may have a hard time concentrating. They may have trouble taking care of themselves and doing basic things like making meals, bathing, and getting dressed. Alzheimers varies from person to person. It can progress faster in some people than in others, and not everyone will have the same symptoms. In general, though, Alzheimers takes many years to develop, becoming increasingly severe over time. As the disease gets worse, people need more help. Eventually, they require total care. Alzheimer's disease consists of three main stages: mild (sometimes called early-stage), moderate, and severe (sometimes called late-stage). Understanding these stages can help you care for your loved one and plan ahead. Mild Alzheimers Disease In the mild stage of Alzheimers, people often have some memory loss and small changes in personality. They may have trouble remembering recent events or the names of familiar people or things. They may no longer be able to solve simple math problems or balance a checkbook. People with mild Alzheimers also slowly lose the ability to plan and organize. For example, they may have trouble making a grocery list and finding items in the store. Moderate Alzheimers Disease In the moderate stage of Alzheimers, memory loss and confusion become more obvious. People have more trouble organizing, planning, and following instructions. They may need help getting dressed and may start having problems with bladder or bowel control. People with moderate Alzheimers may have trouble recognizing family members and friends. They may not know where they are or what day or year it is. They also may begin to wander, so they should not be left alone. Personality changes can become more serious. For example, people may make threats or accuse others of stealing. Severe Alzheimers Disease In the severe stage of Alzheimer's, people usually need help with all of their daily needs. They may not be able to walk or sit up without help. They may not be able to talk and often cannot recognize family members. They may have trouble swallowing and refuse to eat. For a short overview of Alzheimers, see  Understanding Alzheimers Disease: What You Need to Know. Learn More About Alzheimers Disease So far, there is no cure for Alzheimers, but there are treatments that can prevent some symptoms from getting worse for a limited time. Here are some ways you can learn more about Alzheimers disease. - Talk with a doctor or other healthcare provider who specializes in Alzheimers disease.   - Check out books or videos about Alzheimers from the library.   - Go to educational programs about the disease.   - Visit the website of the National Institute on Agings Alzheimers Disease Education and Referral (ADEAR) Center. The Institute has a guide, Caring for a Person with Alzheimers Disease,which can be viewed online and ordered in print.   - Read about  Alzheimers disease on NIHSeniorHealth.  - Find a support group for caregivers, ideally one in which members are taking care of someone who is in the same stage of Alzheimers as the person you are caring for.

Talking With Family and Friends When you learn that someone has Alzheimers disease, you may wonder when and how to tell your family and friends. You may be worried about how others will react to or treat the person. Others often sense that something is wrong before they are told. Alzheimers disease is hard to keep secret. When the time seems right, be honest with family, friends, and others. Use this as a chance to educate them about Alzheimers disease. You can share information to help them understand what you and the person with Alzheimers are going through. You can also tell them what they can do to help. You can help family and friends understand how to interact with the person who has Alzheimers. - Help them realize what the person can still do and how much he or she can still understand.  - Give them suggestions about how to start talking with the person. For example, "Hello George, I'm John. We used to work together."  - Help them avoid correcting the person with Alzheimers if he or she makes a mistake or forgets something.  - Help them plan fun activities with the person, such as going to family reunions or visiting old friends. Help them realize what the person can still do and how much he or she can still understand. Give them suggestions about how to start talking with the person. For example, "Hello George, I'm John. We used to work together." Help them avoid correcting the person with Alzheimers if he or she makes a mistake or forgets something. Help them plan fun activities with the person, such as going to family reunions or visiting old friends. Helping Children Understand Alzheimers If the person with Alzheimers has young children or grandchildren, you can help them understand what is happening. Answer their questions simply and honestly. For example, you might tell a young child, "Grandma has an illness that makes it hard for her to remember things." Know that their feelings of sadness and anger are normal. Comfort them. Tell them they didn't cause the disease. If the child lives with someone who has Alzheimers, don't expect him or her to "babysit" the person. Make sure the child has time for his or her own interests and needs, such as playing with friends and going to school activities. Spend time with the child, so he or she doesn't feel that all your attention is on the person with Alzheimers. Many younger children will look to you to see how to act around the person with Alzheimers disease. Show children they can still talk with the person and help them enjoy things. Doing fun things together, like arts and crafts or looking through photo albums, can help both the child and the person with Alzheimer's. Challenges for Teens A teenager might find it hard to accept how the person with Alzheimers has changed. He or she may find the changes upsetting or embarrassing and not want to be around the person. Talk with teenagers about their concerns and feelings. Don't force them to spend time with the person who has Alzheimers.
