The authors examined psychiatric emergency cases (n=1219, male 850, female 369) admitted to a psychiatric hospital in Tokyo over a 53-month period (from December 1978 to April 1983), to examine the correlation between monthly numbers of psychiatric admissions and meteorological factors.
The results were as follows: 1) Psychiatric emergency admissions of male patients made a peak in spring, whereas female patients showed no obvious seasonal fluctuations. 2) Monthly frequency of admissions was positively correlated with the difference between maximum and minimum temperatures among male non-schizophrenic patients, who consisted mainly of cases of alcohol psychosis including alcohol dependency. 3) Neither of female schizophrenic and non-schizophrenic patients showed any significant correlations with meteorological factors in contrast to male patients.
