Cognitive Functioning in Older Adults
Work & Retirement
Mental Health
Religion and Spirituality
COGNITIVE FUNCTION IN OLDER ADULTS
Cognitive mechanics
Cognitive pragmatics
Speed of processing
Considerable individual variation in
this ability
ATTENTION
•

•
•
Selective attention
Divided attention
Sustained attention
Executive attention
MEMORY
Episodic memory - Younger adults
have better episodic memory
Semantic memory - Does not decline
as drastically as episodic memory
Explicit and implicit memory - The
latter is less likely to be adversely
affected with aging than the former
Working memory and perceptual
speed - Decline during the late
adulthood years
MEMORY
Source memory - Ability to remember where one learned
something
Prospective memory - Involves remembering to do
something in the future
Executive functioning
Aspects of working memory that especially decline in
older adults involve:
Updating memory representations that are relevant for
the task at hand
Replacing old, no longer relevant information
Decision making - Preserved rather well in older adults
USE IT OR LOSE IT
Use it or lose it
Certain mental activities can
benefit the maintenance of
cognitive skills
Research suggests that:
Mental exercise may
reduce cognitive decline
Lower the likelihood of
developing Alzheimer’s
disease
TRAINING COGNITIVE SKILLS
Improve the cognitive skills
of many older adults
Some loss in plasticity in
late adulthood, especially in
the oldest-old
Cognitive vitality of older
adults can be improved
through cognitive and
physical fitness training
TRAINING COGNITIVE SKILLS
Objective: To determine the effects of cognitive training on daily function and
durability of training on cognitive abilities.
Design: N= 2832 persons, 5 year follow-up of a randomized controlled with
4 treatment groups.

WORK & RETIREMENT
Work
Cognitive ability is one of the
best predictors of job
performance in older adults

RETIREMENT
In the US:
On average, workers will spend
10%-15% of their lives in
retirement
Life paths for individuals in their
60s are less clear today
7 million retired Americans
return to work after they retire
Different reasons to work after
retirement
ADJUSTMENT TO RETIREMENT
Older adults who adjust best to
retirement are:
Healthy
Active and have adequate income
Are better educated
Have extended social networks and
family
Satisfied with their lives before
retiring
Flexible and plan key factors
MENTAL HEALTH
Depression
Gender differences
Common predictors
Earlier depressive symptoms
Poor health or disability
Loss events
Low social support
DEPRESSION
Treatable by combination of medications
and psychotherapy.
Cognitive Behavior therapy
Interpersonal therapy
25% of individuals who commit suicide in
the U.S. are 65 years of age or older
DEMENTIA & ALZHEIMER’S
Dementia: Involve a deterioration of mental functioning
20% of individuals over the age of 80 have dementia
Alzheimer disease:
Gradual deterioration of memory, reasoning, language,
and eventually, physical function
Women are likely to develop Alzheimer disease
Causes:
Deterioration of the brain
Formation of amyloid plaques and neurofibrillary
tangles
Lifestyle

Early detection & drug treatment
Mild Cognitive Impairment
fMRI shows smaller brain regions involved in memory for
individuals with MCI
Drug treatment of Alzheimer disease
Cholinerase inhibitors and other drugs slow the
downward progression of the disease
Caring for individuals with Alzheimer disease
Support is often emotionally and physically draining for
the family

Respite care services
PARKINSON DISEASE
Parkinson disease: A chronic,
progressive disease
characterized by muscle
tremors, slowing of movement,
and facial paralysis
Causes
Several treatments are available
FEAR OF VICTIMIZATION, CRIME, & ELDER
MISTREATMENT
Fear of crime
Institutional abuse

Older adults receive disproportionately
fewer mental health services
RELIGION & SPIRITUALITY
• Older adults are spiritual
leaders in many societies
around the world
• Older adults have higher
levels of life satisfaction,
self-esteem, and optimism
• Religion provides important
psychological needs
