Sex differences in schizophrenia.

Demographic and clinical characteristics of 275 schizophrenics consecutively admitted to seven hospitals were examined. Males were younger than females when first hospitalized, diagnosed and treated. Psychiatrists rated on two rating scales by using a structured interview to compare the symptomatology. Female schizophrenics were more agitated, inappropriate, silly, irrelevant, over-talkative, and exhibiting more flight of ideas, while male schizophrenics were more slowed, hypoactive, grandiose, withdrawn, and showing more blocking, auditory hallucinations and poor communications. Katz Adjustment Scales were rated by the patients and their relatives. Female schizophrenics were perceived by relatives to be more helpless and withdrawn-depressed than male schizophrenics.
