Q

prefrontal cortex changes at a structural level

A

gray matter - reduction in the number of cells (due to cell death) or may be a sign of neuronal shrinkage
white matter - axonal abnormalities, slowed neurotransmission

Q

what is hemispheric asymmetry reduction

A

on tasks leading to unilateral prefrontal activity in young adults, older adults tend to show bilateral recruitment (might be compensatory activation or pathological changes such as hemispheric release from inhibition)

Q

domain-general theories of aging

18
Q

three domain general hypothesis of age-related declines

A

sensory deficits, inhibition, speed of processing

19
Q

sensory deficits theory

A

cognitive changes with aging may be attributed to changes in sensations, but possible that there is a common influence underlying both

20
Q

two lines of research in sensory deficit theory

A

older adult’s performance on cognitive tasks correlates strongly with their sensory abilities, in young adults cognitive impairments can arise when stimuli are degraded

21
Q

inhibition theory

A

cognitive deficits may relate to the inability to ignore irrelevant information in the environment while focusing attention on goal-relevant stimuli

22
Q

inhibition theory experiment

A

after reading “before going to bed, please turn off the stove”, older adults more likely to believe that the target word was light - garden path sentence

23
Q

speed of processing theory

A

older adults have a slower speed of processing - poorer encoding of information, reduced ability to store information

24
Q

domain specific theories of cognitive aging

A

propose that some age-related declines may not be explained by core deficits but by changes that have a larger impact on one area of cognition than on another

25
Q

word-finding difficulties manifestations

A

excessive use of pronouns, decreased accuracy and increased reaction time when naming, increased tip-of-the-tongue experience

26
Q

tip-of-the-tongue state

A

a person has access to a word’s meaning, but not to the phonological features of the word (accuracy of the phonological information also lower)

27
Q

summation of priming

A

good at generating words when there are lots of links converging - apple

28
Q

episodic memory

A

memory for the item perviously encountered and memory for contextual details in which the item was encountered

29
Q

what happens when older adults are given a strategy to use as they learn information

A

as good as younger adults - deficits in encoding

30
Q

cognitive aspects that don’t decline

A

creativity, language skills and capabilities, social skills

31
Q

how is emotional regulation after 60

A

better - lower rates of depression, good moods last longer, able to rebound more quickly from negative mood states, focus more on positive information, choose activities based on emotional fulfillment

32
Q

is memory for emotional information preserved

A

some aspects - more likely to remember contextual details if the event contains emotional relevance

33
Q

what improves with age

A

crystallized intelligence (defining words, answering questions related to general world knowledge, detecting spelling errors, carrying out skills related to jobs that they have held for many years) + pragmatic wisdom (what should be done in complex situations)

34
Q

what factors influence aging

A

nutrition and consumption patterns, physical exercise

35
Q

mild cognitive impairments what are

A

deficits don’t impair their ability to function in daily life but do exceed those that typically accompany healthy aging

36
Q

previous names for MCI

A

benign senescent forgetfulness, age-associated memory impairment

37
Q

criteria for MCI

A

subjective memory compliments, impairment in one area of cognition (1.5 sd below age norms), deficits aren’t severe enough

38
Q

autopsy for the first Alzheimer patient

A

intracellular neuritic plaques and extracellular neurofibrillary tangles

39
Q

how many cases of dementia are AD

A

2/3

40
Q

how is semantic memory with AD

A

relatively spared, deficits arise with progression of the disease - especially on word-finding tasks

41
Q

current research semantic memory AD

A

examining the extent to which the breakdown in semantic memory is due to changes in the structure of the memory networks or to difficulties retrieving the stored informaiton

42
Q

neural changes in AD

A

early - MTL most affected - hippocampus atrophy
amygdala - essential for enhancing individual’s memory for highly emotional events
the nucleus basalts - cell loss - acetylcholine transmission (isn’t just this - therapy with this hormone doesn’t solve it)
later - increased atrophy in the MTL, frontal lobe, temporal lobe
very late stages - most structures, sensory regions

43
Q

DSM IV for dementia

A

short term memory problems, cognitive problems in at least 1 other domain, serious enough so as to influence daily functioning, clear consciousness (no hallucinations)
