[Differential diagnostic assessment of IV glucose tolerance in affective disorders (author's transl)]

Glucose intolerance should be regarded as an unspecific, though obligatory phenomenon in endogenous-involutional phases and as an unspecific adaptive finding in somatically based depression. Therefore, it is without differential diagnostic meaning in classifying depressive disorders. On the other hand, normal values of glucose tolerance found in depressive syndromes clinically diagnosed as endogenous-involutional represent a likelihood of underlying organicity.
