...Takao Hashimoto; Jun Tanimura; Takehiro Yako Introduction: Functional thalamic surgery is known for alleviating isolated focal hand dystonia; however, the optimal target site in the thalamus is not determined. This study aimed to identify effective sites for thalamic deep brain stimulation (DBS...

... are ataxia, gait disturbance, paresthesias, dysgeusia, and hemiparesis. Here, we report the first case of thalamic hand dystonia rapidly occurring after MRgFUS thalamotomy of the ventral intermediate nucleus (V.im). Case Presentation: MRgFUS thalamotomy was performed in a 60-year-old left-handed patient...

... was conducted on use of FUS for non-FDA approved movement disorders. All movement disorders excluding FDA-approved uses for ET and PD were included. Results: A total of 25 studies on 172 patients were included. In patients with tremor plus dystonia syndromes ( n = 6), ventralis intermediate nucleus...

Blumenthal-Barby; Gabriel Lazáro-Muñoz Introduction: Pediatric deep brain stimulation (pDBS) is commonly used to manage treatment-resistant primary dystonias with favorable results...

...Anna Stroud; Stephen Tisch; Benjamin P. Jonker Background: Cerebral palsy (CP) is a common cause of acquired dystonia, which can lead to significant interference with quality of life and societal participation. In the last two decades, the surgical treatment of dystonia has primarily focused...

... leads. Here, we describe the case of a 29-year-old patient with generalized dystonia implanted with 4 DBS electrodes and 2 implantable pulse generators, who had an off-label spinal MRI without regard for manufacturer guidance yet suffered no adverse effects. This suggests that manufacturer guidelines...

...Dorian M. Kusyk; Gabriel Costa; Clemens M. Schirmer; Alexander C. Whiting; Joshua M. Rosenow Background: The US Food and Drug Administration (FDA) has granted deep brain stimulation (DBS) approval under the humanitarian device exemption (HDE) pathway for both dystonia and obsessive-compulsive...

Few...

...Veronica Tavares Aragão; Sara Carvalho Barbosa Casagrande; Clarice Listik; Manoel Jacobsen Teixeira; Egberto Reis Barbosa; Rubens Gisbert Cury Meige syndrome is a segmental form of dystonia. It is a disabling disease, especially when refractory to treatment with botulinum toxin. A well-established...

...Xi Bai; Peter Vajkoczy; Katharina Faust Objective: The pathophysiology of dystonia is poorly understood. As opposed to secondary forms of dystonia, primary dystonia has long been believed to lack any neuroanatomical substrate. During trajectory planning for DBS, however, conspicuous T2...

...Takashi Asahi; Kiyonobu Ikeda; Jiro Yamamoto; Hiroyuki Tsubono; Yuko Muro; Shuji Sato There have been limited studies regarding stereotactic and functional neurosurgery for lingual dystonia. Here, we report a patient with primary lingual dystonia who showed significant improvement after bilateral...

...Assel Saryyeva; Hans Holger Capelle; Thomas Mehari Kinfe; Christoph Schrader; Joachim K. Krauss Introduction: Deep brain stimulation (DBS) of the globus pallidus internus has become an accepted treatment for severe isolated idiopathic and inherited dystonia. Patients who had other forms of surgery...

... not been proven. Objective: To assess whether sedation or general anesthesia (GA) improve the quality of MR imaging (MRI). Methods: The records of DBS procedures for Parkinson’s disease (PD), dystonia, and essential tremor in our tertiary neurosurgical unit between January 2011 and June 2016 were reviewed...

...Richard Ågren; Jiri Bartek Jr.; Anders Johansson; Patric Blomstedt; Anders Fytagoridis Introduction: A wide range of pulse widths (PWs) has been used in globus pallidus internus (GPi) deep brain stimulation (DBS) for dystonia. However, no specific PW has demonstrated clinical superiority...

... symptoms. We present two exceptional cases of secondary focal dystonia induced by the mass effect on the basal ganglia caused by giant diencephalic PVSs. In both cases, we chose a surgical stereotactic drainage approach as a treatment strategy that allowed controlling the movement disorders. The beneficial...

... settings when switching from CV NRC to CC RC technology. Methods: We prospectively collected data from 11 consecutive patients (10 men, mean age at DBS implantation 52.6 ± 14.0 years) with chronic DBS for dystonia ( n = 7), Parkinson disease ( n = 3), and essential tremor ( n = 1) who underwent IPG...

... border [ 5 ]. FGATIR MR images were used to measure the distance from PUT-based target to PCB. This distance is reported to be related to DBS efficacy in patients with dystonia [ 3,4,9,19,24,28 ]. WIDTHc (width at the widest point in the GPi) was also measured in all patients. The PUT-based target...
