Read the passage about psychologists and psychiatrists. Many people think psychologists and psychiatrists are the same kind of doctors, but while both are concerned with mental health, their training and practices are different.

A psychiatrist is a medical doctor. Psychiatrists work with severe cases of mental illness and focus on managing medication for their patients. Psychologists, on the other hand, usually have a doctoral degree in psychology. They are trained to diagnose types of mental illness and work in therapy with patients to modify their behaviors.
