Geropsychology is the study of aging and provision of clinical services for older adults. As researchers, geropsychologists expand knowledge of aging and design interventions to address common problems. As practitioners, they help older persons and families overcome issues to enhance well-being. Common problems for the elderly include physical/cognitive decline, loneliness, poverty, health issues, and discrimination. Depression and anxiety are also prevalent, sometimes triggered by life changes. Psychotherapies like relaxation techniques, cognitive behavioral therapy, reminiscence therapy, and family therapy can help address mental health issues facing the elderly.
