[Illness duration and age-repartition of depressive patients without treatment (author's transl)]

The authors have studied the histories of some depressed patients during the period between the World Wars who didn't receive any treatment; they classified them by using modern criteria. They found out that the cases of unipolar depression had spent relatively short time at the hospital. There was no evidence for a difference between the periods before and after the introduction of shocks and thymoleptic drugs.
