Schizophrenia is considered a severe and persistent mental illness. Could you clarify the difference between this type of disorder and other types of mental illness such as anxiety disorders or SAD?

Answered by Raquel E. Gur, M.D., Ph.D.:
Schizophrenia is a distinct disorder both in symptoms and course, and the underlying biology. While high anxiety is common in people with schizophrenia, they have additional symptoms, including deficits in thought processes, functioning, interpersonal relations and impaired perceptions of reality.
