Experimental
Sham Comparator
DBS
SHAM
The medical device includes: Either a pacemaker ACTIVA PC (Ref 37601) two-channel (Medtronic USA) or two pacemakers Activa SC (Ref 37603) to a channel (Medtronic USA) Two DBS electrodes with four contacts (type Medtronic DBS 3389). Patients will be operated with the usual stereotactic surgical procedure. The target is the Accumbens nucleus. The two electrodes are implanted in a single session under local anaesthesia or intermittent sedation (propofol parenteral without intubation early intervention). Day 0 is defined by the surgery. The DBS is "on" during 6 months (between Month 1 and Month 7). Stimulation will also be on after Month 7.
