What is a Psychiatrist?

A psychiatrist is a medical doctor who specializes in the prevention, diagnosis, and treatment of mental and emotional problems. Many people do not realize that serious physical diseases, such as hormone problems or neurological diseases can produce symptoms that resemble mental illness. As a physician who has learned about physical and psychological illness, the psychiatrist is the only mental health professional who is able to tell the difference between physical and emotional diseases, order laboratory tests, and prescribe medications. A fully trained psychiatrist with two additional years of training in the study of childhood development, evaluation and treatment of children’s emotional illnesses may take an examination to be certified in child and adolescent psychiatry. Similarly, one additional year of training and/or examination may lead to certification in geriatric psychiatry or forensic psychiatry.
