dementia Flashcards
define dementia
results from an acquired brain disease; characterized by a progressive decline in memory and other cognitive domains that interferes with daily living and independent functioning
what are some symptoms associated with dementia?
- memory loss
- behavioral
- personality changes
- problems w/ executive functioning
- attention and processing speed impairment
- disorientation
- perceptual changes
- language
dementia is also known as…
major cognitive disorder
what are the requirements for dementia?
significant decline from previous levels of performance in one or more of the cognitive domains
what are the requirements for dementia? pt. 2

cognitive deficits do not occur exclusively in the context of delirium
cognitive deficits are not better explained by other mental disorders

eating
toileting
transferring

true or false: dementia is an umbrella term used to describe a range of symptoms associated with cognitive impairment
true
what are the 3 levels of dementia characterization
- clinical: the symptoms
- neuroanatomical: the location in the brain
- neuropathological: the disease
what are symptoms of Alzheimer’s
early stage deficits in episodic and working memory
later stage impairments in semantic memory
relatively spared procedural memory in early to middle stages of disease
what are symptoms of vascular dementia
cognitive symptoms are heterogenous depending on the lesion distribution
cortical lesions are associated with amnesia, visuospatial deficits, and aphasia
subcortical lesions are associated w/ impairments of memory, executive functions, attention, and motor function
what are symptoms of Lewy body?
fluctuating presentation of cognitive symptoms
procedural memory and learning deficits may occur with subcortical pathology
declarative memory systems may be impaired w/ cortical pathology
frequently overlaps w/ Parkinson’s
what are symptoms of frontotemporal dementia
extreme changes in behavior
some subtypes have…
-language problems and motor disorders
usually at a younger age than Alzheimer’s
