Causes include genetic abnormalities such as Down syndrome, premature birth, exposure to toxins, and others. Symptoms include developmental delay, behavioral issues, or difficulties in school. There is no specific treatment, but some may benefit from dietary changes, medications, and therapies. -
Dementia Due to HIV Infection
Dementia and general cognitive decline is a hallmark of later-stage HIV infections, and is known as AIDS dementia complex (ADC). Thinking, memory, judgement, concentration, and motor function may all suffer as a result of this condition. While HIV/AIDS is incurable, antiretroviral therapy can not only prevent, but also reduce the severity of symptoms in people who have it already. -
Dementia in ALS (Lou Gehrig's Disease)
Amyotrophic lateral sclerosis (ALS) affects the voluntary nervous system that causes muscles to weaken, leading progressively to paralysis and death, usually within five years of the first symptoms. ALS, or Lou Gehrig's disease, usually doesn't cause cognitive impairment, but is sometimes accompanied by dementia due to destruction of cells in the frontal lobe of the brain. -
Dementia in Head Injury

With some serious or repeated brain trauma, dementia can result. Symptoms include memory loss, problems thinking clearly, insomnia, and many others. -
Dementia Medication Overview
There is no good way to treat the progressive condition of dementia, but several different classes of medications can improve the symptoms and slow the patient's decline, especially if paired with diet and lifestyle changes. Drug classes include acetylcholinesterase inhibitors, N-methyl-D-aspartate blockers, and experimental amyloid deposit inhibitors. Antidepressant and antipsychotic drugs can help with problematic behavioral changes. -
Encephalitis
Encephalitis is an acute infection and inflammation of the brain itself. This is in contrast to meningitis, which is an inflammation of the layers covering the brain. Encephalitis symptoms and signs include headache, fever, fatigue, seizures, and photophobia. Treatment depends upon the cause of the encephalitis. -

Dementia With Lewy Bodies
Dementia with Lewy bodies or Lewy body dementia is the name for a group of in which dementia is caused by the presence of Lewy bodies in the brain. The cause of formations of Lewy bodies in the brain is not known. Symptoms of dementia with lewy bodies include recent loss of memory, difficulty conentrating or paying attention, misperceptions of space and time, the inability to think or reason, anbnormal movements of Parkinson's disease, depression, delusions, agitation, and unexplained fainting. Treatment of dementia with Lewy bodies is focused on lifestyle changes, care for the individual with dementia with Lewy bodies, and medicaiton to manage symptoms. -

Meningitis is an infection of the layers around the spinal cord called meninges. This potentially life-threatening condition can be caused by bacteria, viruses, fungus, or reactions to medications or environmental toxins. -
Possible Early Dementia
Dementia is marked decline in brain function that affects memory, thought processes and speech. Alzheimer's disease is a major cause, but many other different factors can cause permanent or reversible dementia. Dementia should be distinguished from the benign age-related forgetfulness many experience, which only superficially affects daily life. Mild cognitive impairment is a memory-loss state more significant than age-related senescence describe above, but less severe than Alzheimer's. -
Normal Pressure Hydrocephalus
Normal pressure hydrocephalus is a brain disorder that develops in older adults. Hydrocephalus happens when the drainage of the cerebro-spinal fluid that surrounds the brain and spinal cord is blocked. The fluid builds up in the hollow ventricals inside the brain, and the excess pressure can cause dementia, and physical symptoms similar to Parkinson disease. Treatment includes implanting a shunt with a valve that drains the excess fluid when the pressure reaches a certain point. -
Parkinson Disease Dementia
Parkinson's Disease (PD) is a degenerative disorder of the brain. It mainly affects movements of the body. Severe cognitive impairments associated with PD are a form of dementia. Symptoms of Parkinson's Disease Dementia include various types of cognitive impairment, such as loss of decision-making ability, disorientation in familiar surroundings, inflexibility to adapting changes, and more. The condition is diagnosed via neuropsychological testing. Various classes of prescription medications are used to treat the condition. -
Pick Disease
Pick disease is a form of dementia characterized by a slow decline of mental abilities caused by damaged brain cells. The disease is similar to Alzheimer's. It is a terminal disease, but some drugs such as antidepressants, antipsychotics, and others can slow the progression. -
Progressive Supranuclear Palsy
Progressive supranuclear palsy (PSP) is a disease that causes the brain to degenerate, leading to problems with movement and balance, loss of cognitive function, memory, speech, and attention. This loss ultimately leads to dementia, and PSP usually affects those over 60. There is no treatment for this disease, the symptoms of which are sometimes similar to Parkinson Disease. -
Stroke-Related Dementia
Dementia is a blanket term to describe significant cognitive and memory decay that could be caused by a number of different conditions. A stroke is a bleed or blockage in the blood vessels that may starve parts of the brain of oxygen. Thought and memory impairment due to a stroke is called vascular dementia. Medications and behavioral therapy may prevent further strokes and slow cognitive decline, but stroke damage cannot be repaired after more than a few hours after the event.
