Common and severe mental illness

Mental health is a high public health priority area.

Common mental health disorders are conditions that cause marked emotional distress and interfere with daily function, but do not usually affect a person's cognition, insight and perception of reality. They comprise different types of depression and anxiety, and include obsessive compulsive disorders. Severe mental illness includes schizophrenia, bipolar affective disorder and other psychoses.
