The general term for a disorder that disrupts thoughts, feelings, moods, and behavior to the extent that it impairs functioning in daily life is mental illness. Mental illnesses are nervous system disorders that result in problems with thinking, mood, or relating with other people. They are severe enough to affect a person's quality of life and make it difficult to perform routine tasks.

These disorders are described in the Diagnostic and Statistical Manual of Mental Disorders (DSM) published by the American Psychiatric Association.
