Multicenter Comparative Study of the Activity of the Medial Prefrontal Cortex in Vulnerability to Depression (CORVAD)

October 5, 2015 updated by: Assistance Publique - Hôpitaux de Paris

Medial Prefrontal Cortex and Vulnerability for Depression

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
BOLD signal in the medial prefrontal cortex
Time Frame: 18 month
Each subject will have a standardized psychometric assessment (BDI-21, MADRS, STAI, RRS) in a Siemens 3T Trio for collecting voxel BOLD signal (Blood-Oxygen-Level Dependent). For each subject and each voxel, a coefficient beta relative activation will be obtained with a general linear model using the timing of presentation of stimuli and the expected signal to model the measured hemodynamic BOLD response. A main effect of condition (personal versus general) will be sought to determine the peak activation within the dorsal CMPF (defined region of interest using the Pickatlas software). The primary endpoint will be the beta coefficient on the level of activation of a sphere 10 mm in diameter centered on the peak.
18 month

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
depression relapse
Time Frame: 1 year
The presence (MINI) and intensity (BDI) for possible depressive relapse will be sought from the attending psychiatrist and during telephone interviews at 6 and 12 months.
