A

Prevalence: 7.1% in 65+y/o

36
Q

DEMENTIA: Causes

A

Alzheimer’s (50-75%): Atrophy of cerebral cortex & formation of amyloid plaques & neurofibrillary tangles. Acetylcholine production in affected neurons is reduced.
Vascular (20%): Result of reduced blood supply to brain, caused by cerebrovascular disorders - eg infarcts
Lewy Bodies (10-15%): Cortical & subcortical Lewy bodies, similar features to Parkinson’s
