Late Adulthood/Death and Dying Flashcards
Gerontology
The study of social, biological and psychological aspects of aging
Geriatrics
Clinical physical issues related to aging
Geriatric psychiatry
Mental health and aging
- Differentiating changes of normal aging from symptoms of psychiatric disorders
- Modifiability of illness in late life
- Distinguishing between changes in early-onset psychiatric disorders who have now aged, and disorders that began in later life
- Modifiability of normal aging to improve functioning
Two groups of Geriatric Psychiatry
- Young-old (65-90)
2. Old-old (90 and beyond)
Fastest growing segment of US population
85 and older
- Projected 10 million by 2025
- Projected 20 million by 2050
Why is there an increase in the older population?
Baby boom
States with highest percentage of 65 and older population
North Dakota South Dakota Iowa Arkansas Florida West Virginia Pennsylvania Maine Connecticut Rhode Island
Projected population growth in Wisconsin (65 and older)
2000: .70 million
2030: 1.36 million
Ratio of men to women in 65 and over population
More women than men
- Ratio favors women as we age
Which racial group is the fastest growing in the 65+ population
Hispanic (White 65+ population is decreasing)
Marital Status of 90+ (Males vs Females)
Males: 42.9% Married; 49.3% Widowed
Females: 6.3% Married; 84.2% Widowed
Centenarians: Proportion of total population
Increasing between 1980 and 2000s
Centenarians (Male/Female ratio)
Percent males decreases as approaching 100 years old
Percent females increases as approaching 100 years old
Cognitive Changes of aging
1) Intellectual performance (peak in 30s, plateau through 60s, rapid decline in 70s)
2) Decrease in fine touch sensation
3) Decline in ability to rise from chair and preform ADLs
4) Mild Neuronal cell loss, blood flow decreases
5) Myelin decreases in white matter
6) Sensory losses (all senses)
7) Random cell loss except in hypothalamus, hippocampus, cerebellum, brainstem, and frontal lobes
Neurogenesis
1) Birth of new neurons (from neural stem cells)
2) New cells compete with old cells (losers die)
3) Occurs throughout life
4) Chronic Stress suppresses cell proliferation
5) Physical activity and exercise promote
Neurogenesis occurs in predominately what two regions of the brain?
Subventricular zone lining lateral ventricles
Subgranular zone - part of dentate gyrus of hippocampus
(May even occur in neocortex and cerebellum)
Fluid Intelligence
Decreases
- One’s ability to think and react quickly
- Mental flexibility and speed of information processing
- Learn new information
Crystallized Intelligence
Stable
- Knowledge or experience accumulated over time and verbal skills
Cognitive changes in Normal Aging
- Memory: Remote memory preserved; recent memory takes longer
- Attention: Simple focused attention is preserved; divided attention is more challenging
- Language: Verbal abilities preserved; word retrieval more difficult
- Executive function, Reasoning and Problem Solving: Maintained - use strategies developed in middle adulthood
Projected number of AD cases in Individuals above age 65
Currently: 5.3 million
By 2050: 13.5 million
What disease has had the highest percentage change in causes of death
Alzheimer’s Disease
What increases in the brain with Alzheimer’s
Neurofibrillary tangles and Amyloid plaques
First two structures to atrophy in Alzheimer’s
Hippocampus, then Frontal lobe
Erik Erikson Stage 8
Integrity vs. Despair
1) Integrity is a sense of satisfaction that life has been productive and worthwile
2) Despair is a loss of hope and a sense that life has no purpose or meaning
Common Life Changes in Aging
- Retirement
- Physical Changes: senses
- Health
- Mobility
- Memory
- Death of spouse, other family, and friends
- Home and personal possessions
- Income
Older Adult Responses to Loss or Changes
Denial Guilt Loneliness Overly-Critical Rigidity Stubbornness Selective Memory Anger Reminiscence Depression/Anxiety
How many people die in the US annually
2.5 million (60 million worldwide)
Bereavement
4 Bereaved people for each death
10 million bereaved people in US (3% pop.)
Complications to Bereavement (30%)
- 1-2 million individuals yearly
Major Depression (15-30%) PTSD (based on circumstances of death) Complicated Grief (10-20%)
Stages of Grief
1) Denial
2) Anger
3) Bargaining
4) Depression
5) Acceptance
