Overview of Dementia

Dementia is the progressive decline in cognitive function beyond what can be expected from normal aging. There are various different types of dementia, and they affect a substantial portion of the elderly population.

Alzheimer's Disease is the most common form of dementia. Other common types include Vascular Dementia, Parkinson's Disease Dementia and Lewy-Body Dementia. There is considerable overlap between these various conditions.

Frontotemporal Dementia is a more rare condition that tends to develop earlier in life.

Mild Cognitive Impairment is the term given to early signs of dementia, usually of the Alzheimer's type, before the full syndrome has set in.
