What this Trial Is About

This is a single-center study about patients with severe resistant OCD. Main assumption is that performing 10 tDCS sessions with the anode positioned at the level of the right orbitofrontal cortex, and the cathode at the level of the supplementary motor area, associated with the provocation of symptoms before each session is effective in the reduction in obsessive-compulsive symptoms. After the inclusion visit, the treatment period is provided from D1 to D12 (one session per day from Monday to Friday, for two consecutive weeks, i.e. a total of ten sessions). Each tDCS session lasts 30 minutes at an intensity of 2 mA and is preceded by symptom provocation using a standardized procedure performed by trained personnel. The patients are then assessed on D42 and D102 (i.e. 1 month and 3 months after the end of the tDCS sessions).
