what are subcortical dementias
dementia with lewy bodies or lewy body dementia
- lewy body proteins found in brainstem which depletes dopamine and causes parkinsonian symptoms
- also found in cortex
- 2nd most common type of progressive dementia after alzhemiers
- symptoms: hallucinations, impaired mobility, muscle rigitity, dementia
what is huntingtons disease
subcortical dementia
-hereditary disorder that causes degeneration in brain resulting in movement disorder and cog decline
what is alzhemiers
cortical dementia
- accounts for 60-80%
- neurofribrtillary tangles and neuritic plaques with amyloid

what is the prognosis
- patients with AD retain higher capacity in implicit memory than originally thought
- no cure exists
- major depression uncommon, but have periods of depression
- patients with late onset 40-60% expereince psychotic symptoms
what is level 1 of the global deteroriation scale
