“…This is concordant with findings of Pasamanick & Knobloch (1961), who demonstrated a connection between perinatal complications and later development of schizophrenia. It is still another possibility that the material of schizophrenics includes some cases of symptomatic schizophrenia or schizophrenia-like psychoses based on focal brain lesions (Slater & Beard (1963), Herrington (1969), West (1973)), but the frequency of these psychoses in our material is unknown. We have no estimate of the impact of perinatal complications on the cohort of schizophrenic patients.…”

From a register comprising all psychiatric in‐patients in Denmark, a sample was selected consisting of all schizophrenic and manic‐depressive patients admitted in the period 1969–1973, a total of 7,427 schizophrenic and 8,212 manic‐depressive patients. A comparison was carried out between the distribution of month of birth in the patient group and in the background population of live births from the corresponding years. A surplus of schizophrenic patients born in the first trimester was found, whereas the pattern of the manic‐depressive patients did not deviate from that of the background population. The monthly birth indices for the schizophrenic and manic‐depressive patients were compared with the monthly birth indices found for still‐births. A positive correlation was found between schizophrenia and still‐birth. This is compatible with the theory which ascribes a role to obstetric complications in the genesis of schizophrenia. No evidence of such influence was found in manic‐depressive psychosis.

There is overwhelming empirical evidence for the influence of genetic factors in the etiology of schizophrenic psychoses. An appreciable and still increasing number of exogenous factors have been known for decades that are capable of inducing psychoses that present as "schizophrenia" or are more or less similar to it. In this article, genetic disorders--chromosomal abnormalities and Mendelian diseases--are summarized that may be associated with such psychoses. These disorders frequently but not necessarily exhibit additional physical symptoms. Although the majority of schizophrenic psychoses can so far not be explained by exogenous factors or well-defined genetic disorders, the proportion of these etiologies among all cases may be higher than presumed so far, because they evade detection. Data from the literature are discussed in the light of Karl Bonhoeffer's early concept of exogenous reaction types and modern medical genetics.
