Dementia is a condition characterized by the gradual decline of brain functions, including memory, thinking, and reasoning abilities. It is caused by various diseases and conditions that damage brain cells, such as Alzheimer's disease. Occupational therapists play an important role in helping dementia patients maintain their functional abilities and independence for as long as possible through various approaches, including health promotion, remediation, maintenance, and environmental modification. While there is no cure for dementia currently, occupational therapy aims to improve patients' well-being and delay institutionalization by supporting caregivers and providing customized care.
