Study Notes
Forces of Natural Selection and Aging
- Hamilton's forces of natural selection suggest aging may plateau, implying that aging can halt.
- Physiology of adults undergoing aging differs significantly from that of younger life phases.
Active Aging
- Defined as optimizing health, participation, and security to enhance quality of life in older adults.
- Initiatives for Active Aging promote overall health as individuals age.
Exogenous Sources of Free Radicals
- Common sources include tobacco smoke, pesticides, organic solvents, radiation, ozone, and certain medications.
- Free radicals damage cellular components like DNA, proteins, and lipids, contributing to aging and diseases.
Biological Theories of Aging
- Focus on deleterious effects that reduce organism functionality over time.
- Errors in DNA and RNA synthesis accumulate, leading to cell death (Error/Orgel Theory).
- Environmental agents and events can introduce errors, exacerbating cellular change and aging.
Aging Dynamics
- Aging processes vary among organs in organisms; not all age simultaneously.
- A healthy aging concept should not focus on merely the absence of disease.
Health Systems and Aging
- Current health systems often struggle to cater to the growing needs of older populations.
- Investments in older individuals' health should be viewed as valuable resources, not merely costs.
Genetic Factors in Aging
- Approximately 25% of longevity diversity is attributable to genetics; environmental factors significantly affect aging.
- Aging requires an integrated system of long-term care, particularly as populations age.
Misconceptions about Aging
- Aging is diverse; older individuals can have physical and mental capacities comparable to younger individuals.
- The assumption that older populations are predominantly care-dependent is inaccurate.
Common Health Conditions in Older Age
- Frequent conditions include hearing loss, cataracts, osteoarthritis, and chronic diseases like diabetes and dementia.
- Older adults often face multiple simultaneous health conditions, termed geriatric syndromes.
Activities Promoting Healthy Aging
- Maintaining healthy behaviors such as balanced diets, regular physical activity, and sleep hygiene greatly influences healthy aging.
- Adequate sleep enhances mental clarity, energy, weight control, and immune function.
- Strength training and nutrition are vital for preserving muscle mass and cognitive function as one ages.
