This study was designed to determine the seasonality of serotonin functions among adolescents who attempt suicide. Platelet 3Himipramine binding was assessed over 18 months in 98 adolescent attempters & a comparison group of 23 never-suicidal youths with conduct disorder. 3Himipramne (Bmax) was uncorrelated with age, but showed considerable seasonal variability over time in those who had attempted suicide, reaching a nadir in late winter/early spring.
