Troubles affectifs et troubles de la personnalité

Coexistence in an individual of an affective disorder and a personality disorder is very common and there is an abundant literature on it. Articles are numerous and heterogeneous ; the results are sometimes imprecise or discordant. Some data are, despite these reserves, shared by the scientific community. The main consensus is first on a bad prognosis, with a high rate of all DSM axes comorbidities, secondly on the trap of a same phenomenology for different underlying mechanisms. A review is presented.
