AbstractObjective.  Deep brain stimulation (DBS) increasingly attracts attention as a potential treatment of mental disorders. Beside depression and obsessive-compulsive disorders, DBS has already been shown to be beneficial for Tourette syndrome (TS). Clinical Presentation/Method.  The authors report on the outcome of a patient with treatment-resistant TS who underwent bilateral DBS of the nucleus accumbens and the internal capsule. Results.  Within the 10-month follow-up, a substantial reduction of tics has been observed. Yet, as a side-effect of DBS, the patient developed a transient manic-like episode when primarily stimulated by the most proximally contact in the internal capsule. Conclusions.  This case supports the hypothesis that DBS of the nucleus accumbens and the internal capsule represents an effective therapeutic alternative for otherwise treatment-resistant TS. Yet, future controlled studies are needed to determine optimal stimulation parameters and to reduce negative side-effects such as transient hypomanic episodes.© 2008 International Neuromodulation Society.
