The results of stroke vary widely depending on size and location of the lesion. Physical effects
Some of the physical disabilities that can result from stroke include muscle weakness, numbness, pressure sores, pneumonia, incontinence, apraxia (inability to perform learned movements), difficulties carrying out daily activities, appetite loss, speech loss, vision loss and pain. If the stroke is severe enough, or in a certain location such as parts of the brainstem, coma or death can result. Up to 10% of people following a stroke develop seizures, most commonly in the week subsequent to the event; the severity of the stroke increases the likelihood of a seizure. An estimated 15% of people experience urinary incontinence for more than a year following a stroke. 50% of people have a decline in sexual function (sexual dysfunction) following a stroke. Emotional and mental effects
Emotional and mental dysfunctions correspond to areas in the brain that have been damaged. Emotional problems following a stroke can be due to direct damage to emotional centers in the brain or from frustration and difficulty adapting to new limitations. Post-stroke emotional difficulties include anxiety, panic attacks, flat affect (failure to express emotions), mania, apathy and psychosis. Other difficulties may include a decreased ability to communicate emotions through facial expression, body language and voice.Disruption in self-identity, relationships with others, and emotional well-being can lead to social consequences after stroke due to the lack of ability to communicate.
The toxicity may also result from non-combustible sources such as the one released from anaerobic fermentation of food grains and anaerobic digestion of biodegradable waste.The World Health Organization (WHO) developed a global recommendation limiting exposures to less than 20 parts per billion for chronic exposure and value less 100 ppb for one hour for acute exposure, using nitrogen dioxide as a marker for other pollutants from fuel combustion. There is a significant association between indoor NO2 levels and increased respiratory symptoms such as wheeze, chest tightness and severity of infections among children with asthma. Historically, some cities in the United States including Chicago and Los Angeles have higher levels of nitrogen dioxide than the EPA maximum exposure limits of 100 ppb for a one-hour exposure and less than 53 ppb for chronic exposure. Signs and symptoms
Nitrogen dioxide poisoning is harmful to all forms of life just like chlorine gas poisoning and carbon monoxide poisoning. It is easily absorbed through the lungs and its inhalation can result in heart failure and sometimes death in severe cases. Individuals and races may differ in nitrogen dioxide tolerance level and individual tolerance level for the gas may be altered by several factors, such as metabolic rate, barometric pressure, and hematological disorders but significant exposure may result in fatal conditions that could lead to shorter lifespan due to heart failure. Acute poisoning
Exposure to high level of nitrogen dioxide may lead to inflammation of the mucous membrane and the lower and upper respiratory tracts.
