The seasonality of mania: Preliminary findings.
The relationship between climatic variables and monthly manic admissions to a teaching hospital in Riyadh, Saudi Arabia was examined over a six-year period. The results indicate a weak but significant correlation between monthly admission rates of mania and day length, humidity, air pressure, and temperature. The correlation did not seem, however, to be strong enough to indicate a seasonal trend. Also, current month climatic variablesare better correlated than previous months. The prevalence of sunshine throughout the year may explain the low correlation with mania admissions unlike reports from other countries.
