P0091 - Sex differences in the outcome of first episode psychosis

Abstract

Objective:

Evaluate the sex differences in first episode psychosis.

Methods and material:

We present an open prospective and muti – center study with a follow – up of 2 years in patients with a first psychoses episode. The patients were treated with risperidone and assessments were made in the first month and then every three months for 2 year. Therefore, we used a protocol including the following scales: PANSS, Global Assessment of Functioning scale (GAF-EEAG), CGI, Young mania rating scale, Hamilton scale for the depression, UKU, OCS, Premorbid Adjustment scale (Cannon-Spoor), the Information Subtest (WAIS) and Psychosocial Stress Global Assessment (DSM III R).

Results:

231 patients were included (32.5% women). Males have consistently an earlier onset even after controlling the cofounding factors and poorer premorbid functioning. Women have a shorter DUP, and they are more likely to be married than men and to live with their couples or children. Women have also better adherence to treatment than men. Males don't show differences in negative, positive symptoms or cognitive deficits. There was no difference between the sexes in the dose of the prescribed antipsychotic. There are no clear sex differences in family history and obstetric complications. Sex doesn't have influence on the course of illness in middle-term (2 years).

Conclusion:

This paper supports the presence of significant differences between schizophrenic males and women, but there aren't differences in the outcome of the disease.
