Aktiv komparator: stimulation on
At first stage, electrodes will be implanted in all patients, who will be continuously stimulated for several months.
After this stage, the random-crossed part of the study will start, and patients who responded to DBS will be randomly distributed in two groups: on stimulation or off stimulation group, for the next three months.
Subsequently, patients will be allocated in the other group (on or off, crossed part) for three months

Surgical electrode implantation in the white matter adjacent to the Cg25 region and implantation of the DBS pulse generating device
