The morbidity risk for affective disorders was calculated among the relatives of subgroups of reactive-neurotic depressive patients. The patients were divided into reactive and neurotic depressives. The parents of the neurotic subgroup had a significantly lower morbidity risk of affective disorders in comparison with the parents of the reactive subgroup. The role of genetic and environmental factors in the etiology of reactive-neurotic depression was discussed.
