Investigations into the Significance of the Endocrines in Involutional Melancholia

Abstract
The question whether involutional melancholia in females can be regarded as distinct form of mental illness representing a reaction to bodily changes following the menopause has been amply discussed. It has been held by some that such a melancholia is no more than one phase of the manic-depressive psychosis (1, 2). Others hold the opposite view and justify it on statistical and clinical grounds (3).
