London: A clinical psychologist is a mental health professional with highly specialized training in the diagnosis and psychological treatment of mental, behavioral, and emotional illnesses.
Clinical psychologists do not prescribe medications to treat mental illness, except in a handful of states where they do have that authority. Rather, they use psychological techniques, such as cognitive-behavioral therapy (CBT) and psychoanalytic therapy.

Psychologist vs. Psychiatrist:
The biggest difference between a psychologist and a psychiatrist is that a psychiatrist is a medical doctor (MD) who can prescribe medications, while most psychologists are not medical doctors and typically cannot prescribe medication.
While psychologists may also have a doctorate, it is not a medical degree. Psychiatrists go through a year of medical internship followed by three years of residency in treating and diagnosing mental illnesses. Psychologists usually do one to two years of internship after completing their degrees.
