Longevity relationships between the mentally abnormal and their parents

Abstract

Schizophrenic and manic-depressive patients were found to die at an earlier age than their parents. Correlations between the ages of death indicate that there is a closer relationship between the age of death of schizophrenics and their parents than between manic-depressives and their parents. The correlations between the ages of death of the patients and their mothers were significantly higher than those between the patients and their fathers.
