Dementia Flashcards
dementia
aquired syndrome of decline in memory and other cognitive functions in an alert patient that alters ADLS
basic ADL’s
basic biological and self-care tasks
instrumental ADL’s
allows for independent living in a community
four cognitive domains
recent memory
executive function
visuospatial ability
language
recent memory
ability to learn and recall new info
language
either comphrension or expression
visuospatial ability
comphrension and effective manipulation of nonverbal, graphic or geographic
executive function
ability to plan, preform abstract reasoning, solve problems, focus despite distractions and shift focus when appropriate
Mini-cog test
3-minute screening tool for cognitive impairment
- 3 item recall and clock draw
what must happen before diagnosing dementia
rule out metabolic causes
toxicology, ammonia level
when should brain imaging be considered?
- when normal pressure hydrocephalus is suspected
- recent fall or head trauma
- onset less than 65
- focal or asymetric symptoms
normal-pressure hydrocephalus
dilated brain ventricles with normal CSF pressure
-ataxia and urinary incontinece
mild cognitive impairment
- subjective complaint of decline in at least i cognitive domain
- noticeable and measurable
prognosis of mild cognitive impairment
50% remain stable or go back to normal in 3-5 years
50% with depression as well–> dementia within 5 years
distinguishing signs of delirium
- acute onset
- fluctuations in cognition over hours to days
- impaired consciousness and attention
- altered sleep cycles
insomnia is…
a result of dementia
a cause of delirium
distinguishing signs of depression
- low motivation during cognitive testing
- complaints exceed deficits
- maintain language and motor skills
onset and progression of Alzheimers disease
gradual and progressive
cognitive symptoms in Alzheimers disease
memory impairment is the earliest feature and core
when are motor and sensory symptoms seen in alzheimers disease
very late
- apraxia, aphasia, viso-spatial
risk factors for Alzheimers disease
age and family history
onset and progression of Vascular dementia
sudden or gradual
stepwise with further ischemia
abnormalities seen on imagining Alzheimers disease
global atrophy, small hippocampal volumes
abnormalities seen on imaging vascular dementia
cortical or subcortical ischmic changes/infarts on MRI
