Geriatric psychiatry is a subfield of psychiatry that focuses on the mental health needs of elderly patients. As people age, they face a variety of newfound problems, and this often takes a toll on their mental health. In addition, chronic illnesses can have a negative effect on mental processes and emotional processing. With the help of a geriatric psychiatrist, older people can live longer, healthier, and more fulfilling lives as they go through the aging process.

Medical professionals who specialize in neuropsychiatry work to help patients who have mental illnesses that can be directly attributed to neurological disorders or problems. This field has grown in recent years as it has become clearer that many mental illnesses are the result of physical problems of the brain. It is a more specialized field than their neurology or psychiatry, and therefore, patients must seek out this specific type of care if their mental illness is related to a brain disorder.
