Historically, melancholia has given place to depression, to become a p
articular sub-type of the latter, characterized by pay chomotor retard
ation, symptomatic severity, importance of the somatic and vegetative
disorders, presence of psychotic symptoms, possible biological (mainly
neuro-endocrinian) abnormalities, and good response to the biological
treatment. A personal study on 30 patients considered as typical conf
irms the diagnostic stereotypes of the French clinicians. However, the
critiera selected by the DSM-III and -IV of the APA are more problema
tic (for the CIM-10 of the WHO, melancholia is a vestigial synonym of
''severe depression''). Accepting cases of medium severity, they turn
melancholia into a more frequent pathology (two-thirds of the patients
hospitalized for depression), synonym of ''endogenous'' or ''psychoti
c'' depression. This model of relatively severe, episodic pathology di
ffers from the psychodynamic conception of melancholia, which might co
rrespond to the inter-critical mental state, likely comparable to the
''typus melancholicus'' of the unipolar forms of depression. Here rema
ins the problem of the accessibility to the rather little documented p
sychotherapies, whether they are of psychoanalytical or cognitive insp
iration.
