Gerontology is the scientific study of aging and the processes related to aging. This interdisciplinary field encompasses various aspects of aging, including physiological, psychological, and social changes that occur as people grow older. Researchers in gerontology study topics such as age-related diseases, health and wellness in older adults, changes in cognitive function, caregiving, and end-of-life issues. The goal of gerontology research is to better understand the aging process and to improve the quality of life for older adults.
