Psychiatric Disorders in Foster Home Reared Children of Schizophrenic Mothers

The place of genetic factors in the aetiology of schizophrenia remains disputed. Several surveys have demonstrated a significantly higher incidence of the disorder in relatives of schizophrenic persons as compared to the general population. Furthermore, the closer the relationship, the higher the incidence of schizophrenia. The studies of Kallmann (1938) and Slater (1953) are especially significant and the research in this area has been thoroughly reviewed by Alanen (1958).
