First episode psychosis in an adult area mental health service-a closer look at early and late-onset first episode psychosis.

OBJECTIVES: To review the characteristics of all patients presenting with a first episode of psychosis between the ages of 16 and 65 years to an adult area mental health service.
METHODS: The early psychosis programme at St Vincent's Hospital Melbourne treats all patients presenting in the early stages of psychosis between the ages of 16 and 65 years. A database was developed to capture the demographic and diagnostic characteristics of the group. The characteristics of those with an onset under 26 years were compared with those with a later onset.
RESULTS: A large proportion (55%) of those presenting with first episode psychosis presented after the age of 25 years. There were a higher number of cases of depression with psychotic features in the older onset patients (notably so for those over 40) and a trend towards greater metabolic morbidity. DISCUSSION: Older patients presenting with a first episode of psychosis are relatively understudied but appear to have certain distinguishing qualities. Understanding the needs of these patients is important in tailoring optimal treatment packages and service responses. © The Royal Australian and New Zealand College of Psychiatrists 2014.
