adult cognition is the process of…
Acquiring
Storing
Sharing
Using information
components of adult cognition
- Language
- Thought
- Memory
- Executive function
- Organization (gather info)
- Regulation (evaluate and change behavior)
- Judgment
- Attention
- Perception
adult cognition in action
- Orientation
- Problem solving
- Psychomotor ability
- Reaction time
- Social intactness
cognition physiological changes with age
Neuron loss
- most pronounced in cerebral cortex
Brain atrophy
- decreased weight
Dendrites atrophy
- impaired synapse
- changed transmission of dopamine, serotonin, and acetylcholine
not consistent with deteriorating mental function
Slowing is NORMAL (not processing as quickly
- IMPAIRMENT IS NOT NORMAL (not being able to remember things at all)
cognitive reserve (CR)
Ability to compensate for age-related changes
“use it or lose it” - applied to cognitive function as well as physical health
- based on the concept of neuroplasticity (capacity of the brain to change in response to stimuli)
maximizes cognitive reserve
- Engage in cognitive, sensory, and motor activities
- Engage in meaningful social interaction regularly
fluid intelligence
Native intelligence or “street smarts”
Biologically determined skills INDEPENDENT of learning or experience
- thinking, inductive reasoning, abstract thinking, and integration
Ability to identify and draw conclusions
crystallized intelligence
“book smarts”
Knowledge and skills acquired during life
- verbal meaning, word association, social judgment, number skills
classic aging pattern
- Fluid intelligence decreases while crystallized intelligence remains stable
- Related to speed of cognitive processing and slower reaction time
learning late in life
basic intelligence remains unchanged with increasing years
cognitive assessment
- Evaluation of cognitive function requires formal focused assessment
- Complete assessment, including lab workup, should be performed to rule out any medical causes of medical impairment
myths about the aging brain
box 5.1, p 57
tips to improve memory
table 5.1, p 59
3 components to memory
- Immediate recall
- Short term memory
- Remote or long-term memory
memory retrieval
Recall of newly encountered information decreases with age
- Memory declines noted for complex tasks and strategies
age-associated memory impairment (AAMI)
- Considered normal memory loss (general slowness in processing, storing, and recalling new information and difficulty in remembering names and words)
- Offset with cognitive stimulation and memory training
mental health and aging
- Nearly 20% over 55 y/o experience mental health disorders that are not part of normal aging
- Underreported and not well researched
- Can be affected by cognitive and affective functioning earlier in life
common mental disorders later in life
- Depression
- Anxiety
- Mood disorders
- Alcohol abuse and dependence
stress overload
- Increased by changing environmental needs and reduced of biopsychosocial homeostatic resilience
- Diminishes ability to cope effectively
effects of stress
- Reduces coping ability
- Impairs neuroendocrine response that blunts immune function
- Research on psychoneuroimmunology explored relationship between stress and various health conditions, cancers, Alzheimer’s disease, frailty, an functional decline - pro inflammatory cytokines
flourishing despite adversity (tend to develop as you age)
Resilience
- successfully adapting to difficult and life challenging experiences
- positive interpersonal relationships
- high self-esteem and self-efficacy
- sense of purpose
- creativity and sense of humor
control, commitment, & challenge
Hardiness
- stress is a challenge and an opportunity for growth
- social connectedness
- confronting problems head-on
- extending oneself to others
- spiritual grounding
toolbox of self-control skills & belief that the tools may be used effectively
Resourcefulness
- self-control
- self-direction
- self-efficacy
Coping
- Coping may contribute more to health of older adults because they use it to optimize their resources
- Coping strategies are factors that help individuals maintain psychosocial balance during stressful periods
- Includes identifying stressor – good, bad, indifferent
- Using skills & resources
- Using past experiences as a resource
- Using these appropriately
