 Approximately 25 of people who are admitted to hospitals for depression suffer from psychotic depression. People with psychotic depression experience hallucinations,and, more commonly delusions, in addition to major depression. Psychotic experiences may be either congruent with the theme of depression or incongruent, without an apparent relationship to feeling depressed. This study will determine the effectiveness of combining a selective serotonin reuptake inhibitor SSRI with antipsychotic medication in the treatment of psychotic depression accompanied by at least one identifiable delusion. The study will also evaluate the difference in treatment response of young adults versus geriatric patients.
