What types of dementia are there?

Some dementia is reversible and can be cured partially or completely with treatment. The degree of reversibility often depends on how quickly the underlying cause is treated. Irreversible dementia is caused by an incurable condition (e.g., Alzheimer’s disease). Patients with irreversible dementia are eventually unable to care for themselves and may require

round-the-clock care.

Alzheimer's disease - Alzheimer's dementia is the most common type of dementia, and is caused by a loss of brain cells. It is at least partly a hereditary disease, in that it tends to run in families. (Just because a relative has Alzheimer disease, however, does not mean that another family member will have the disease.) In this disease, cells in the areas of the brain that control memory and mental functions are destroyed by abnormal protein deposits in the brain. People with Alzheimer disease also have lower-than-normal levels of brain chemicals called neurotransmitters that control important brain functions. Alzheimer disease is not reversible, and there is no known cure. There are, however, medications that can slow its progress.

Vascular dementias, including multi-infarct dementia - Vascular dementias is the next most common type of dementia, and is caused by poor circulation of blood to the brain. In multi-infarct dementia, lots of tiny strokes (or infarcts) occur which cut off the blood supply to part of the brain. The progression of vascular dementia can happen in recognised steps. With this type of dementia, good control of blood pressure, good diabetic control and avoiding cigarettes may help to slow the progress.

Parkinson disease - People with this disease typically have limb stiffness (which causes them to shuffle when they walk), speech problems, and tremor (shaking at rest). Dementia may develop late in the disease, but not everyone with Parkinson disease has dementia. Reasoning, memory, speech, and judgment are most likely to be affected.

Lewy body dementia - This is caused by abnormal microscopic deposits of protein in nerve cells, called Lewy bodies, which destroy the cells over time. These deposits can cause symptoms typical of Parkinson disease, such as tremor and muscle rigidity, as well as dementia similar to that of Alzheimer disease. Lewy body dementia is more likely, however, to affect thinking, attention, and concentration than memory and language. Like Alzheimer disease, Lewy body dementia is not reversible and has no known cure. The drugs used to treat Alzheimer disease also benefit some people with Lewy body disease.

Alcohol-related dementia - Brain damage can be caused by drinking too much alcohol. It is important that people with this type of dementia give up drinking alcohol completely to stop the disease progressing.

Pick disease (frontotemporal dementia) - Pick disease is another rare disorder that damages cells in the front part of the brain. Behavior and personality changes usually precede memory loss and language problems.

More information on dementia (Alzheimer's disease, vascular dementia, lewy body dementia, Pick's disease)

What is dementia? - Dementia is a deterioration of intellectual function and other cognitive skills. Dementia may involve progressive deterioration of thinking, memory, behavior, personality and motor function.
What types of dementia are there? - Types of dementia include Alzheimer's dementia, vascular dementias, Parkinson disease, Lewy body dementia, alcohol-related dementia, and Pick disease.
What're the risk factors for dementia? - The main risk factor for dementia is age. People who have sustained serious head injuries through boxing are prone to dementia pugilistica.
What causes dementia? - Dementia is caused by degeneration in the cerebral cortex including death of brain cells, conditions that impair the vascular or neurologic structures of the brain.
What're the symptoms of dementia? - The early symptom of dementia is diminished short-term memory. Patients with severe dementia cannot perform activities of daily living.
How is dementia diagnosed? - Diagnosis of dementia begins with a thorough physical exam and complete medical history, and followed by information-concentration-orientation test of Blessed et al. and the mini-mental state exam of Folstein et al.
What's the treatment for dementia? - The goal of treatment is to control the symptoms of dementia. Treatment of dementia begins with treatment of the underlying disease.
What's the long term dementia care? - Long-term dementia care may be needed for some patients with dementia. Possible options include in-home care, boarding homes, adult day care, and convalescent homes.
What's alcohol-related dementia? - Alcohol related dementia is a form of dementia related to the excessive drinking of alcohol. Alcohol abuse can lead to several forms of dementia.
What's frontal lobe dementia? - Frontal lobe dementia is a set of degenerative diseases producing many of the same symptoms as vascular dementia. The frontal lobe governs people's mood and behaviour.
What's senile dementia? - Senile dementia is the mental deterioration (loss of intellectual ability) that is associated with old age. Senile dementia is often used when referring to Alzheimer's disease.
What's early onset dementia? - Early onset dementia is a term that covers a range of diseases affecting memory and thinking in people under the age of 65.
What's AIDS related dementia? - HIV associated dementia (HAD) is comprised of a spectrum of conditions from the mild HIV-1 motor cognitive-motor disorder to severe and debilitating AIDS dementia.
What's Alzheimer's disease? - Alzheimer's disease is a form of degenerative brain disease resulting in progressive mental deterioration with disorientation, memory disturbance and confusion.
What types of Alzheimer's disease are there? - Types of Alzheimer's disease include early onset Alzheimer's, late-onset Alzheimer's, and familial Alzheimer's disease (FAD).
What're the stages of Alzheimer's disease? - Stages of Alzheimer's disease include no cognitive impairment, mild cognitive decline, moderate cognitive decline, moderately severe cognitive decline...
What causes Alzheimer's disease? - The ultimate cause or causes of Alzheimer's disease are still unknown, there are several risk factors that increase a person's likelihood of developing the disease.
What're the risk factors for Alzheimer's disease? - The risk for Alzheimer's disease increases with age. People with a family history of Alzheimer's have a greater risk.
What're the warning signs of Alzheimer's disease? - The warning signs of Alzheimer's disease include memory loss, difficulty performing familiar tasks, problems with language, poor or decreased judgment.
What're the symptoms of Alzheimer's disease? - The symptoms of Alzheimer's disease include memory lapses, perform routine tasks, loss of judgment, and personality or behavior changes.
How is Alzheimer's disease diagnosed? - Diagnosis of Alzheimer's disease is complex. Diagnosis of Alzheimer's disease begins with a thorough physical exam and complete medical history.
What's the treatment for Alzheimer's disease? - Some treatments for Alzheimer's disease that can be used to help manage and ease the symptoms. Medications help alleviate the symptoms of depression, anxiety, and delusions.
What medications treat Alzheimer's disease? - Four medications, tacrine, donepezil, rivastigmine tartrate and galantamine, are used to improve intellectual function in some patients with Alzheimer's disease.
What's the dietary therapy for Alzheimer's disease? - Dietary therapy for Alzheimer's disease involves appropriate intake of darkly colored fruits and vegetables, soy, alcohol, folate and vitamin B12.
What's the exercise therapy for Alzheimer's disease? - Aerobic exercise is very important for helping to protect against mental decline during aging due to Alzheimer's disease.
What's the prognosis of Alzheimer's disease? - A person with Alzheimer's disease lives an average of eight years and as many as 20 years or more from the onset of symptoms.
What's vascular dementia? - Vascular dementia is a common form of dementia in older persons that is due to cerebrovascular disease, usually with stepwise deterioration.
