Abstract: Deep brain stimulation (DBS) is an emerging therapeutic option for
severe resistant Tourette syndrome (TS). To date, about 100~cases have been
reported in the scientific literature. Different clinical guidelines have been
proposed for this procedure from both USA and European centres. A number of
issues remain unresolved, mainly in relation to eligibility criteria of
patients with TS. We highlight the need for a comprehensive assessment of
associated co-morbidities, which are not considered integral part of the
syndrome and are not sufficiently evaluated in relation to DBS. The concept of
refractoriness, the minimum age of candidates, and the optimal targets for DBS
are also controversial.
