Study Notes
Ageism and Aging
- Ageism: prejudice or discrimination against a person based on age
- The Graying of the Population: gradual increase in the proportion of older people in the population
Stages of Aging
- Young old: people aged 65-74, healthy and active majority of older adults
- Old old: people aged 75-84, frail, infirm, and in the minority of older people
- Oldest old: people aged 85 and above
- Primary aging: gradual, inevitable process of bodily deterioration throughout the life span
- Secondary aging: aging processes resulting from disease and bodily abuse and disuse, often preventable
Functional Age and ADLs
- Functional age: measure of a person's ability to function effectively in their physical and social environment
- Activities of Daily Living (ADLs): essential activities that support survival, such as eating, dressing, bathing, and getting around the house
Gerontology and Geriatrics
- Gerontology: study of the aged and the process of aging
- Geriatrics: branch of medicine concerned with processes of aging and age-related medical conditions
Physical Development
- Longevity: length of an individual's life
- Life expectancy: age to which a person is statistically likely to live, based on average longevity of a population
- Life span: longest period for which members of a species can live
Theories of Aging
- Senescence: period of life span marked by changes in physical functioning associated with aging
- Genetic-programming theories: theories that explain biological aging as resulting from a genetically determined developmental timetable
- Programmed senescence: theory of aging in which specific genes "switch off" before age-related losses become evident
- Mitochondria: minute organisms that generate energy for cell processes, whose fragmentation is hypothesized to be a cause of aging
Variable-Rate Theories
- Variable-rate theories: theories explaining biological aging as a result of processes that vary from person to person and are influenced by both internal and external environment
- Metabolism: conversion of food and oxygen into energy
- Wear-and-tear theory: theory that the body ages as a result of accumulated damage to the system beyond the body's ability to repair it
- Free-radical theory: theory that attributes aging to the harmful effects of free radicals
- Rate-of-living theory: theory of aging that suggests that the body can do just so much work, and the faster it works, the faster it wears out
- Autoimmune theory: theory of aging that suggests that an aging immune system can become "confused" and release antibodies that attack the body's own cells
Life Span Extension
- Survival curves: curves showing percentages of a population that survive at each age level
- Hayflick limit: genetically controlled limit, proposed by H...
