They also investigate age-related diseases and conditions, such as dementia, osteoporosis, and cardiovascular disease, and develop interventions to prevent or manage these health problems in older adults. Overall, the goal of research in healthy aging is to help older individuals maintain their quality of life and independence as they grow older.
