Study Notes
Oxidative Free Radical Theory
- Aging attributed to oxidative metabolism and free radicals as by-products.
- Free radicals damage DNA, proteins, and cell membranes, leading to malignancy and accelerated aging.
- Key figure: Hayflick (1985) emphasized oxygen usage and cellular aging.
Stochastic Theories
- Propose that aging results from random damage over time.
- Free radicals generated through oxygen use, especially during physical exertion.
Connective Tissue Theory
- Also known as cross-linking or glycosylation theory, proposed by Johan Bjorksten in 1942.
- Accumulation of cross-linked proteins damages cells, affecting metabolism and increasing aging effects.
- Glucose binding to proteins disrupts molecular structures, leading to various health issues.
Neuroendocrine Theory
- Hypothalamus orchestrates hormonal responses via the pituitary gland, impacting overall health.
- Disruption in hormonal synchronization increases disease susceptibility.
- Aging linked to decreased immune function and altered responses to infections and cancers.
Programmed Theory
- Suggests aging is a genetically programmed aspect of life, not merely biological wear and tear.
- Cells have a finite number of divisions, setting a limit on lifespan.
- Older individuals experience a less effective immune response, mistaking regular cells for foreign entities.
Psychological Theory
- Emphasizes emotional and cognitive aspects of aging, including how societal roles and perceptions shape aging experiences.
Age Stratification Theory
- Highlights how aging affects and is affected by societal structures, categorizing individuals into age-specific groups.
- Observes reciprocal changes among individuals and society, focusing on resource acquisition and roles.
Human Needs Theory
- Developed by Maslow, identifying five tiers of human needs crucial for motivation:
- Physiologic
- Safety and security
- Love and belonging
- Self-esteem
- Self-actualization
- Emphasizes the importance of meeting these needs for older adults to avoid feelings of failure and depression.
Subculture Theory
- Older adults create a distinct subculture to maintain identity against societal rejection.
- This subculture possesses unique norms, interests, and beliefs separating them from younger generations.
Continuity Theory
- Suggests that personality influences behavior and roles, impacting overall happiness in later life.
- Individuals tend to maintain their established habits and values as they age.
Person-Environment-Fit Theory
- Introduced by Lawton; emphasizes the relationship between an older adult's functional competence and their environment.
- Each developmental stage presents crises that must be resolved for healthy aging.
Gerotranscendence Theory
- Developed from Erickson's stages of development, extends to seven stages in late adulthood.
- Focuses on achieving ego integrity and finding meaning through life experiences.
Conclusion
- Various theories offer insights into the aging process, emphasizing biological, psychological, and sociological factors.
- Understanding these theories aids in improving care and enhancing quality of life for older adults.
