Study Notes
Geriatrics and Gerontology
- Geriatrics is a medical specialty focused on healthcare for elderly individuals.
- Gerontology studies the aging process and the challenges associated with aging.
Life Span and Life Expectancy
- Life span refers to the maximum number of years an individual can live.
- Life expectancy is the average number of years a person is expected to live based on statistical averages.
Geriatric Physical Therapy
- Geriatric physical therapy focuses on improving mobility, strength, and function in elderly patients.
- It aims to enhance the quality of life through tailored rehabilitation programs.
Aging Population Statistics
- By 2030, it is projected that approximately 20% of the population will be over 65 years old.
Leading Causes of Mortality in Elderly
- The leading causes of death in individuals over 65 include heart disease, cancer, Alzheimer’s disease, and stroke, listed in order of frequency.
Activity and Life Satisfaction
- The activity theory of aging suggests that the more active elderly individuals are, the more satisfied they feel with life.
Hormonal Theory of Aging
- According to the hormonal theory, the pituitary gland is the primary regulator and timekeeper of aging processes.
Free Radical Theory of Aging
- The free radical theory proposes that reactive and toxic forms of oxygen, called free radicals, are produced by cell mitochondria, contributing to aging.
Elderly Population Demographics
- Individuals aged 75 and older constitute about 60% of the elderly population.
Immunity Theory of Aging
- The immunity theory suggests that decreases in thymus size and function lead to reduced immune system efficacy as people age.
- There is a steady decrease in immune responses during adulthood, contributing to age-related health issues.
Atchley’s Theory
- Atchley’s theory posits that older adults adapt to maintain a sense of continuity between their past experiences and present life.
Aging Pigments and Wrinkles
- According to the free radical theory, aging pigments known as lipofuscins accumulate due to oxidative stress.
- Wrinkles and reduced skin elasticity are caused by the loss of collagen and elastin over time.
Understanding Older Adults in Physical Therapy
- Physical therapy in geriatrics is designed to enhance understanding of the unique needs of older adults and address their specific health concerns.
Sensitivity to Cold and Bedsores
- Aging leads to decreased thermoregulation, making individuals more susceptible to cold (hypothermia) and increasing the risk of bedsores.
