Abstract

Objective: To report on patients with comorbid Obsessive-Compulsive Disorder (OCD) and a psychotic disorder, and to discuss the relationship between OCD and psychosis. Method: Case histories of seven patients seen at a rural mental health clinic in New Zealand are presented. Six of them were treated with selective serotonin uptake inhibitors (SSRIs). Results: Four patients had sexual obsessions and two reported aggressive obsessions. One patient had obsessive doubts and checking compulsions. Six patients improved with the addition of an SSRI to their ongoing neuroleptic medication. Conclusions: 1) OCD and psychosis may coexist by chance and may be unrelated. 2) An obsession may become a delusion or vice versa. 3) A reactive delusion of guilt or persecution may develop. 4) An obsession may trigger a psychotic episode or vice versa. 5) Obsessions may be misdiagnosed as delusions or hallucinations. 6) Recognition and treatment of OCD may improve the outcome of psychosis.
