There are many measures that can improve the quality of life of people with dementia and their caregivers. Cognitive and behavioral interventions may be appropriate for treating associated symptoms of depression. Signs and symptoms
The signs and symptoms of dementia are termed as the neuropsychiatric symptoms, also known as the behavioral and psychological symptoms of dementia. Behavioral symptoms can include agitation, restlessness, inappropriate behavior, sexual disinhibition, and aggression, which can be verbal or physical. These symptoms may result from impairments in cognitive inhibition. Psychological symptoms can include depression, psychotic hallucinations and delusions, apathy, and anxiety. The most commonly affected areas include memory, visuospatial function affecting perception and orientation, language, attention and problem solving. The rate at which symptoms progress occurs on a continuum over several stages, and they vary across the dementia subtypes. Most types of dementia are slowly progressive with some deterioration of the brain well established before signs of the disorder become apparent. Often there are other conditions present such as high blood pressure, or diabetes, and there can sometimes be as many as four of these comorbidities.People with dementia are also more likely to have problems with incontinence: they are three times more likely to have urinary and four times more likely to have fecal incontinence compared to people of similar ages.Dementia symptoms can vary widely from person to person. It affects memory, attention span, communication, reasoning, judgement, problem solving and visual perception, etc.
This is mainly a problem with producing speech. They have trouble finding the right words, but mostly they have a difficulty coordinating the muscles they need to speak. Eventually, someone with NFA-PPA only uses one-syllable words or may become totally mute. A frontotemporal dementia associated with amyotrophic lateral sclerosis (ALS) known as (FTD-ALS) includes the symptoms of FTD (behavior, language and movement problems) co-occurring with amyotrophic lateral sclerosis (loss of motor neurons). Two FTD-related disorders are progressive supranuclear palsy (also classed as a Parkinson-plus syndrome), and corticobasal degeneration. These disorders are tau-associated. Huntingtons disease
Huntingtons disease is a neurodegenerative disease caused by mutations in a single gene HTT, that encodes for huntingtin protein. Symptoms include cognitive impairment and this usually declines further into dementia.The first main symptoms of Huntingtons disease often include:

difficulty concentrating
memory lapses
depression - this can include low mood, lack of interest in things, or just abnormal feelings of hopelessness
stumbling and clumsiness that is out of the ordinary
mood swings, such as irritability or aggressive behavior to insignificant things

HIV
HIV-associated dementia results as a late stage from HIV infection, and mostly affects younger people. The essential features of HIV-associated dementia are disabling cognitive impairment accompanied by motor dysfunction, speech problems and behavioral change. Cognitive impairment is characterised by mental slowness, trouble with memory and poor concentration. Motor symptoms include a loss of fine motor control leading to clumsiness, poor balance and tremors. Behavioral changes may include apathy, lethargy and diminished emotional responses and spontaneity.
