[The hypothesis of season of birth as a risk factor in schizophrenia. Recapitulation and critical review]. / L'ipotesi della stagione di nascita come fattore di rischio nella schizofrenia. Rassegna e revisione critica.

ABSTRACT

The literature on the relationship between season of birth and schizophrenia is reviewed. Analysis of the available data suggests that various factors may be involved in causing the phenomenon. The hypotheses that have been formulated on this epidemiological discovery are analysed and a possible interaction between relational and environmental factors presumably implicated in the explanation of the connection in question is suggested.
