What is the most common cause of dementia among people age 65 and older?

What is the root cause of dementia?

Dementia is usually caused by degeneration in the cerebral cortex, the part of the brain responsible for thoughts, memories, actions, and personality. Death of brain cells in this region leads to the cognitive impairments that characterise dementia.

What is the most significant risk factor for dementia?

The greatest known risk factor for Alzheimer’s and other dementias is increasing age, but these disorders are not a normal part of aging. While age increases risk, it is not a direct cause of Alzheimer’s. Most individuals with the disease are 65 and older. After age 65, the risk of Alzheimer’s doubles every five years.

What causes early dementia?

It is caused by genetic mutations (changes in genes) that run in families. Three genes have been found to have these rare mutations – PSEN1 (presenilin 1), PSEN2 (presenilin 2) and APP (amyloid precursor protein). There is a 50% risk of a parent passing on the familial Alzheimer’s disease mutation to their children.

What causes dementia to worsen?

Damage to small blood vessels deep in the brain can cause dementia that worsens gradually, like Alzheimer’s disease. When damage is due to a major stroke (potentially due to the blockage of a major blood vessel) or a series of small strokes, symptoms occur suddenly.
