What does a Psychiatrist like Zrenner specialize in?

A Psychiatrist is a medical doctor (MD) who has completed specialized training in psychiatry, which is the branch of medicine focused on the diagnosis, treatment, and prevention of mental, emotional, and behavioral disorders.

What is the main difference between a Psychiatrist like Zrenner and a Psychologist?

The main difference is that a Psychiatrist, like Zrenner, is a medical doctor (MD) who has completed medical school and then specialized residency training in psychiatry. Because they are physicians, psychiatrists can diagnose mental health conditions, prescribe and manage psychotropic medications, and provide various forms of psychotherapy. They can also order medical tests to rule out physical causes of psychiatric symptoms. A Psychologist typically has a doctoral degree (PhD or PsyD) in psychology and is trained in psychological assessment, diagnosis, and providing psychotherapy (talk therapy). Psychologists generally cannot prescribe medication in Canada, though they often work closely with psychiatrists or family doctors who do.
