Gender difference in the prodromal symptoms of first-episode schizophrenia.
To investigate the gender difference of early symptoms appearing before the onset of the psychotic symptoms in patients with first-episode schizophrenia, we reviewed the medical records of 63 patients (38 males, 25 females), who were hospitalized for first-episode schizophrenia. The frequency and duration of prodromal and psychotic symptoms, Clinical Global Impression scale scores, Global Assessment of Functioning (GAF) scale scores at admission, and other clinical characteristics were recorded for all patients. Overall, the most common prodromal symptoms were attenuated positive symptoms (89%), followed by mood symptoms (86%). Negative symptoms were the most common in male patients (97.4%), whereas attenuated positive symptoms were the most common in female patients (84%). Male patients demonstrated more frequent negative, cognitive, and obsessive-compulsive symptoms than female patients did and also showed a tendency of having negative symptoms for the longer period. Correlational analysis showed a significant negative correlation between the duration of negative symptoms and GAF scores at admission in male patients. Our findings suggest that different patterns of prodromal symptoms between male and female begin before the onset of the psychosis. Further prospective studies should be needed.
