Mental Illness
Mental illnesses refer to disorders generally characterized by dysregulation of mood, thought, and/or behavior, as recognized by the Diagnostic and Statistical Manual, 4th edition, of the American Psychiatric Association (DSM-IV). Mood disorders are among the most pervasive of all mental disorders and include major depression, in which the individual commonly reports feeling, for a time period of two weeks or more, sad or blue, uninterested in things previously of interest, psychomotor retardation or agitation, and increased or decreased appetite since the depressive episode ensued.
