Cognition, dementia, end-of-life care, and death & dying Flashcards
What are Amyloid plaques and tau tangles more prevalent in?
Individuals with dementia
What happens as we age to your brains?
Decreased gray and white matter structure & volume
Especially in frontal lobe
Decreased dopamine concentration, transported availability, and receptor density
Aging brain more susceptible to pathology
Synapses age
What aspects of memory remain relatively stable with age?
Some aspects of memory (especially implicit memory), language, and social cognition remain relatively stable with age
What types of cognitive processes show gradual and declines?
Processing speed, encoding of information into episodic memory, short-term memory, and executive function show gradual and linear declines with aging
What are some typical normal cognitive aging features?
Need increased time for processing
Require more rehearsal to encode information into long-term memory
Have decreased ability to multi-task
Have difficulty with problem-solving
True or false,Some older adults will exhibit no observable slowing of cognition, while others may display noticeable changes that are considered “within normal limits”
True
What is delirium?
Abrupt change in mental status and behavior with impairment in cognitive processes and attention deficits2
Clinical syndrome characterized by disturbed consciousness, cognitive function impairment, and perception1
What is link to delirium?
Linked to increased LOS, morbidity, mortality, discharge to SNF, re-admission1
What group of people are at higher risk of delirium?
Hospitalized older adults are at increased risk, especially in ICU settings
What is dementia?
A clinical syndrome of cognitive and functional decline
Usually chronic or progressive
What are some common subtypes of dementia?
Alzheimer dementia (41%)
Vascular dementia (32%)
Dementia with Lewy bodies (8%)
Frontotemporal dementia (3%)
How do you distinguish delirium from dementia?
What is sundowning?
Syndrome characterized by restlessness, excitement, increased confusion, hallucinations, agitation
Can occur in patients with AD or other types of dementia
Seen in late afternoon or early evening
What is mild cognitive impairment (MCI)?
Still able to carry out normal daily functions & do not experience personality changes
People with MCI have more memory problems than what is considered normal for others of the same age, but symptoms are not as severe as those with Alzheimer’s
A mild neuro-cognitive disorder
Prevalence in individuals 65+ is 15-20%
What are some common signs of MCI?
Losing things
Forgetting appointments
Trouble with word-finding
Forgetting conversations
May be easily distracted
Difficulty managing finances or medications
What is Alzheimer’s disease?
Alzheimer disease: brain disease characterized by amyloid plaques, neurofibrillary tangles, and neuronal loss;4 leading cause of dementia in late adult life2
