Decreasing Tendency of Seasonality in Suicide may Indicate Lowering Rate of Depressive Suicides in the Population

148 suicide events on Gotland, Sweden, between 1981 and 1996 confirmed the seasonality of suicide with a spring and summer peak between 1981 and 1989. This seasonality disappeared between 1990 and 1996, when prescription antidepressants increased dramatically, indicating that more and more depressed patients were pharmacologically treated.
