, Abstract : Objectives : The occurrence of depression in people with epilepsy is almost twice as common as in the general population. Furthermore, depression is the first cause of lower quality of life among those patients. That's why the main goal of this study was to assess the epidemiology of depression and its associated factors among the patients from the tertiary department of epileptology in Rennes. Methods/Results : The subjects were included prospectively and consecutively at the moment of their consultation or hospitalisation in the department. Personnel data about the socio-economic status and the type of epilepsy was collected. The subjects filled validated selfassessment of depression (NDDIE), anxiety (GAD-7) and quality of life (QOLIE-10). Thanks to the NDDIE, the patients were divided in : "depressed" and "not depressed, Objectifs : La survenue d'un syndrome dépressif chez les patients souffrant d'épilepsie est deux fois plus fréquente qu'au sein de la population générale. Cette étude avait pour objectif d'évaluer l'épidémiologie et les facteurs associés à cette comorbidité parmi les patients du centre d'épileptologie de Rennes. Méthodes et Résultats : Les sujets ont été inclus prospectivement et de manière consécutive dans l'étude. Les informations concernant le statut socio-économique, les caractéristiques de l'épilepsie, l'autoévaluation par échelles validées de dépression (NDDI-E), anxiété (GAD-7) et qualité de vie, p.-

, Conclusions : In the tertiary epileptic department of Rennes, more than 20% of patients with epilepsy in our department suffered from depression during the inclusion period according to the NDDIE. Among those "depressed" subjects, less than one out of five seemed to receive a proper psychiatric care, anticonvulsant benzodiazepine medication
