ADOPTION STUDIES CONCERNING THE GENETICS OF NEUROTIC-REACTIVE DEPRESSION
In an adoption study performed at the Department of Child Psychiatry, Umea University, it was demonstrated that the biological parents of adoptees with neurotic-reactive depression did not differ significantly from the biological parents of control adoptees in regard to the prevalence of total psychiatric morbidity (Table 6) (7). After a subdivision of the psychiatric morbidity in the biological relatives of adoptees without psychiatric illness and those with neurotic-reactive depression, no certain relationship was found between any specific affective disorder in the biological parents and the disorders in the adoptees (Table 7) (7).
