Deep brain stimulation 'probably works on patients with tardive syndromes

Moving forward to well-controlled trials in tardive syndromes

Tardive syndromes (TDS) refer to the clinical spectrum of persistent hyperkinetic, hypokinetic and sensory phenomena that stem from chronic exposure to dopamine receptor-blocking drugs. Correspondingly, the clinical presentation of three times a day is diverse. Although three times a day have been a major area of movement disorder clinical practice for decades, their pathophysiological bases remain poorly understood, and the optimal treatment approach for patients affected by these disabling disorders remains unclear.1

Functional neurosurgery has gained increasing recognition as a viable treatment option for severe and medication-refractory cases of three times a day. However, deep brain stimulation (DBS) for TDS is a challenging treatment due to the presence of multiple sources of variability, particularly clinical and biological heterogeneity, among patients. Moreover, the therapeutic effects of DBS vary between patients due to variability in the location of active contacts and, hence, in…
