Treating a Case of First-Episode Psychosis to Uncover Undiagnosed Obsessive Compulsive Disorder: A Case Report.

Obsessive-compulsive disorder (OCD) is a chronic psychiatric condition characterized by the presence of obsessions, compulsions, or both. Historically OCD was associated with good insight. However, there are more categories to the degrees of insight in OCD patients, namely good, fair, poor, absent, or delusional beliefs. It is also important to note that insight can fluctuate circumstantially. We describe a rare case of first-episode psychosis of undetermined cause presenting with suicidal ideation. After continued treatment, it was discovered to be previously undiagnosed OCD with poor insight.
