Geriatric psychiatry is a medical specialty focused on the mental health of older adults. It addresses conditions such as dementia, depression, anxiety, and late-life psychosis, which often occur alongside physical illnesses and cognitive decline. Specialists provide diagnosis, treatment, and supportive care tailored to the elderly, considering biological, psychological, and social factors. Through therapy, medication, and family support, geriatric psychiatry enhances quality of life, independence, and emotional well-being in aging populations.
