What is the diagnostic criteria for dementia?
Acquired, persistent and progressive impairment of intellectual function with compromise of memory and at least 1 other cognitive domain
What are examples of cognitive domain required to dx a pt with dementia?
- Aphasia
- Apraxia
- Agnosia

Is dementia rapid or insidious onset and is it progressive or no?
Insidious and progressive deterioration
Does dementia cause impairment in autonomic arousal and impairment in mentation?
- No impairment in autonomic arousal
- Consistently impaired mentation
Is alertness retained or lost in dementia and is agitation present?
- Alertness is retained in early stages
- Agitation is less prominent
Does dementia vary with stress? and if pt is psychotic what usually occurs in a pt with dementia?
- Varies with stress

What is a common concomitant of early dementia?
Depression
What is dementia w/ lewy bodies?

What medication lessens delirium in a pt with dementia w/ lewy body?
Cholinesterase inhibitors
Is delirium a rapid or progressive onset? And what is the duration?
