A report from the deep brain stimulation (DBS) group in the Netherlands called attention to side effects over the course of treatment in TS patients with thalamic DBS \citep{28102636}.
Michael Okun and colleagues show proof of principle that triggered rather than continuous DBS may be helpful \citep{28960154}. A patient was treated with DBS in the centromedian-parafascicular (CmPf) thalamus region bilaterally, and DBS was controlled by a 5- to 15-Hz signal there. Response was similar to that obtained with continuous DBS, and the battery usage was over 60% lower.
