As global populations age, the demand for specialized mental health services targeting older adults continues to grow. Geriatric psychiatry: aging and cognitive disorders focuses on conditions such as depression, anxiety, late-life psychosis, and dementia. Age-related changes in brain function, medication metabolism, and social circumstances necessitate tailored assessment and treatment approaches. Loneliness, bereavement, and functional decline are common triggers for psychiatric distress in seniors, often complicating medical comorbidities. Interdisciplinary teams that include psychiatrists, neurologists, gerontologists, and caregivers are essential in providing comprehensive care. Preventive strategies, cognitive stimulation therapies, and caregiver support systems are key elements in improving quality of life and preserving dignity in later life.
