Dementia is a loss of cognitive functioning which affects patient memory, thinking and social abilities severely enough to interfere with daily life.

Alzheimer's disease (AD) is the most common cause of a progressive dementia in older adults, but there are a number of other types of dementia which include vascular dementia, frontotemporal dementia and dementia with Lewy bodies.

Vascular dementia is the second most common type of dementia and is caused by a lack of blood flow to the brain. Dementia with Lewy bodies is caused by protein deposits in nerve cells which cause memory loss and disorientation. Frontotemporal dementia describes several types of dementia which affect the language and behaviour areas of the brain and can affect people as young as 45 years old.
