Dysphoric states in the course of manic-depressive illness

The purpose of the present study is to investigate the relationship between dysphoric states (episodes in which irritable mood is prominent and relatively persistent) and manic-depressive illness. A further purpose is to clarify the probable causal influence of chemotherapy and the social consequences concerning dysphoria. The observations carried out on 14 patients are illustrated by 2 case reports. A strong tie seems to exist between dysphoric state and manic-depressive illness, especially with respect to typical biorhythmic disturbances. Although the origin of such states is generally unknown, there are indications that neuroleptics and lithium may play a major role. Social consequences are on the whole minor, if the disturbances in mood and drive occur acutely and markedly. On the other hand, mild to moderate mood changes (especially when unaccompanied by drive changes) may lead to severe social impairment. The reason for this may be that the latter-mentioned states are misinterpreted by the entourage as personality traits rather than as expressions of an illness.
