The well-being of older adults is a major social and health concern in Canada. Geriatric mental health (GMH) refers to the multidisciplinary practice in the assessment and treatment of mental illness or impairment of older adults, from the bio-psycho-social perspective. Older adults often receive inadequate or inappropriate mental health services. Provision of appropriate and effective care is a challenge because of the complexity of determining the differential diagnosis of health problems in elders. A GMH team consists of health professionals such as geriatric psychiatrists, clinical nurse specialists, psychiatric nurses, occupational therapists, and social workers.
