Hand surgery is a field that helps patients with a variety of health issues involving the hands. This can include both surgical and non-surgical care. These doctors treat conditions that present not only in the hands but also the arms. These conditions may include infections, abrasions, injuries, and arthritis. Surgeons trained in orthopedic surgery, general surgery, and even plastic surgery are all qualified to perform surgeries on the hands or provide other treatment for this area.

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.
