Se. Mouridsen et al., SEASON OF BIRTH IN INFANTILE-AUTISM AND OTHER TYPES OF CHILDHOOD PSYCHOSES, Child psychiatry and human development, 25(1), 1994, pp. 31-43
Season of birth in 328 children with infantile autism and other types
of childhood psychoses born between 1945 and 1980 was compared with th
at 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 aut
istic-like disorders, born in the same period a maximum occurred in No
vember, while no seasonality was observed for a borderline sample.
