摘要: Little is known about the results of pallidal deep brain stimulation (DBS) in DYT6 dystonia. This will be first report dystonia treated with DBS from Iran. A 21 years old male patient underwent bilateral stimulation. The target was sensorimotor region posteroventral globus pallidus internus (GPi). parameters included an amplitude 2.7 V, frequency 160 Hz, and pulse width 90 μs which were adjusted according to patient's response 12 months after surgery. Treatment outcome measured by patient’s Burke-Fahn-Marsden Dystonia Rating Scale (BFMDRS) score. Before surgery, BFMDRS score 32. However, reduced 7 at one year follow up surgery (78% improvement total score). Dystonic symptoms extremities mouth completely resolved. Also speech swallowing function significantly improved. Although previous observations reported a poor moderate speech, we found as effective treatment not only for dystonic features, but also
