Tourette syndrome (TS) is a childhood-onset neuropsychiatric disorder that affects
neural circuits involved in sensory and motor processing as well as cognitive control.
Tics consist of repetitive, unwanted, non–goal-directed muscle contractions involving
discrete muscle groups, which are associated with preceding sensory phenomena (urges)
and are variably suppressible by volition (

). Most individuals with TS experience improvement of their tics in late adolescence
or early adulthood. However, a few individuals have severe and self-injurious tics
that are refractory to currently available behavioral and pharmacologic interventions.
Untreated, severe tics can lead to permanent disability and injury (e.g., severe head
snapping tics leading to permanent injury to the cervical spinal cord or persistent
eye-poking tics leading to blindness).To read this article in full you will need to make a payment

- PreviewSince its first application in 1999, the potential benefit of deep brain stimulation (DBS) in reducing symptoms of otherwise treatment-refractory Tourette syndrome (TS) has been documented in several publications. However, uncertainty regarding the ideal neural targets remains, and the eventuality of so far undocumented but possible negative long-term effects on personality fuels the debate about the ethical implications of DBS.
