About Psychiatry

What is a Psychiatrist?

A psychiatrist is a doctor who treats problems with medication. Psychiatrists specialize in the treatment and prevention of mental health, including substance use disorders. Psychiatrists are qualified to assess both the mental and physical aspects of psychological disturbance. A psychiatrist has completed medical school (is an M.D. or D.O.) and residency training in psychiatry

Diagnosing patients

Because they are physicians, psychiatrists can order or perform a full range of medical laboratory and psychological tests which, combined with interviews/discussions with patients, help provide a picture of a patient's physical and mental state. Their education and years of clinical training and experience equip them to understand the complex relationship between emotional and other medical illnesses, to evaluate medical and psychological data, to make a diagnosis, and to work with a patient to develop a treatment plan.

Specific diagnoses are based on criteria established in the Diagnostic and Statistical Manual of Mental Disorders, which contains descriptions, symptoms and other criteria for diagnosing mental disorders.


Medications are used by psychiatrists in much the same way that medications are used to treat high blood pressure or diabetes. After medical and psychological evaluations, psychiatrists can prescribe medications to help treat mental disorders. Psychiatric medications can help correct imbalances in brain chemistry that are thought to be involved in some mental disorders. Psychiatrists often use medications in combination with psychotherapy. Patients on long-term medication treatment will need to meet with their psychiatrist periodically in order to monitor the effects of medications.

Other treatments are also sometimes used by psychiatrists. Electroconvulsive therapy (ECT), a medical treatment that involves applying electrical currents to the brain, is used most often to treat severe depression that has not responded to other treatments. Deep brain stimulation, vagus nerve stimulation, and repetitive transcranial magnetic stimulation are a few of the newer therapies being used to treat some mental disorders.

Psychiatric Training, Certification

To become a psychiatrist, a person must complete college, then medical school, and then a residency in psychiatry. Some psychiatrists also complete additional specialized fellowship training after their general psychiatry training (see below).

Newly graduated physicians must pass written and oral examinations for a state license to practice medicine. After graduation, doctors typically spend much of the first year of residency training in a hospital taking care of patients with a wide range of medical illnesses. The psychiatrist-in-training then spends at least three additional years in a psychiatric residency learning the diagnosis and treatment of mental health, gaining valuable skills in the use of psychiatric medicines.

After completing residency training, most psychiatrists take a voluntary written and oral examination given by the American Board of Psychiatry and Neurology to become a "board certified" psychiatrist. They must be re-certified every 10 years.

Where do psychiatrists work?

Psychiatrists work in a variety of settings, including private practices, clinics, general and psychiatric hospitals, university medical centers, community agencies, courts and prisons, nursing homes, industry, government, military settings, schools and universities, rehabilitation programs, emergency rooms, hospices, and many other places. About half of the psychiatrists in the U.S. maintain private practices and many psychiatrists work in multiple settings.

What is the Difference Between a Psychiatrist and Psychologist?

A psychiatrist is a medical doctor with special training in psychiatry who is able to prescribe medications and other medical treatments.

A psychologist usually has a PhD, most commonly in clinical psychology, and often has extensive training assessment, diagnosis, therapy, and research. Psychologists treat problems with psychotherapy, such as cognitive-behavioral therapy.

Psychotherapy, sometimes called talk therapy, is a treatment that involves a talking relationship between a therapist and patient. It can be used to treat a broad variety of mental disorders and emotional difficulties. The goal of psychotherapy is to eliminate or control disabling or troubling symptoms so the patient can function better. Depending on the extent of the problem, treatment may take just a few sessions over a week or two or may take many sessions over a period of years. There are many forms of psychotherapy and it can be done individually, with a family, or in a group. Some mental health require limited but ongoing treatment in order to manage chronic conditions.
