Abstract

Season of birth in 328 children with infantile autism and other types of childhood psychoses born between 1945 and 1980 was compared with that of a control population born in the same period. For some parts of the period (the years 1951–56, 1963–68 and 1975–80 combined) an excess of March born boys with infantile autism was found. For boys with autistic-like disorders, born in the same period a maximum occurred in November, while no seasonality was observed for a borderline sample.
