Gerontology: The Complete 2024 Guide

Gerontology: Understanding and Improving Aging

What is Gerontology?

Gerontology is the interdisciplinary study of aging across:
✅ Biological processes
✅ Psychological changes
✅ Social impacts
✅ Technological solutions

💡 Did You Know? By 2050, 1 in 6 people worldwide will be over 65 (WHO).

 

Branches of Gerontology

 

1️⃣ Biological Gerontology

Studies cellular aging (telomeres, senescence)

Focuses on longevity interventions

2️⃣ Social Gerontology

Examines aging's impact on:

Family structures

Retirement systems

Ageism in society

3️⃣ Clinical Gerontology (Geriatrics)

Medical care for elderly patients

Manages multiple chronic conditions

4️⃣ Environmental Gerontology

Designs age-friendly cities

Smart home technologies for seniors

Key Theories of
Aging

Theory	Explanation	Implications
Wear-and-Tear	Cellular damage accumulates	Antioxidant research
Genetic Programming	Biological clocks (telomeres)	Gene therapy trials
Free Radical	Oxidative stress causes damage	NAD+ supplements

Emerging Theory: Senescence (Zombie cells) → Anti-aging drugs in trials
