[Investigations of fasting blood glucose in endogenous depressive, schizophrenic, and neurotic patients (author's transl)].

Fasting blood glucose was estimated in endogenous depressive, schizophrenic, and neurotic patients. Mean fasting blood glucose levels were found to be significantly increased in endogenous depressive patients as compared with schizophrenics and neurotics. This finding is thought to be a sensitive symptom for a decrease in glucose tolerance in endogenous depression. No correlation could be detected to sex, body weight: body height ratio or age. Several hypothetical explanations of the finding are discussed.
