What is a Psychiatrist?

A psychiatrist is a medical doctor who specializes in the diagnosis, treatment and prevention of mental illnesses, 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 an additional four or more years of residency training in psychiatry.

People seek psychiatric help for many reasons. The problems can be sudden, such as a panic attack, or frightening hallucinations, thoughts of suicide, or hearing “voices.” Or they may be more long-term, such as feelings of sadness and hopelessness or anxious feelings that never seem to lift, causing everyday life to feel distorted or out of control.

Many FM sufferers experience depression and anxiety.

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.


Psychiatrists use a variety of treatments:

  • 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 illnesses require limited but ongoing treatment in order to manage chronic conditions.
  • 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.  Light therapy used to treat seasonal depression.

What is the Difference Between a Psychiatrist and Psychologist?

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

A psychologist usually has an advanced degree, most commonly in clinical psychology, and often has extensive training in research.  Psychologists treat mental disorders with psychotherapy and some specialize in psychological testing and evaluation.
