We systematically evaluated the efficacy of both unilateral and bilateral stereotactic pallidotomy in eight patients with generalized dystonia. Six patients had a marked improvement in dystonic movements and motor function; the other two patients also benefited from the procedure but to a lesser extent. The severity of dystonia was assessed before and after(More)
The authors report the postoperative magnetic resonance (MR) imaging findings in 36 patients with advanced Parkinson's disease who underwent unilateral microelectrode-guided posteroventral pallidotomy. The lesions were placed within 1 mm of the ventral border of the globus pallidus internus (GPi) to include pallidothalamic outflow pathways. Sequential MR(More)
OBJECT The treatment of solitary vestibular schwannomas by performing Gamma Knife surgery is well established. It has been reported that decreasing the surface dose reduces patient morbidity, especially facial weakness and numbness. The authors of this retrospective study examine patient data from a single center to determine if low-dose (< or = 14 Gy) GKS(More)
Parkinson's disease (PD) is a debilitating neurodegenerative disorder affecting more than 1.2 million people in the United States. Genetic and environmental toxins are believed to be risk factors in acquiring the disease. PD is characterized by tremors, rigidity, bradykinesia, poor gait, and postural instability. These cardinal symptoms improve with(More)
OBJECT The goal of this study was to investigate the impact of mild or moderate degrees of degenerative or ischemic encephalopathy on predicting clinical outcome following unilateral posteroventral medial pallidotomy for treatment of advanced Parkinson's disease (PD). METHODS Thirty-five patients with PD were studied prospectively. The presence and degree(More)
High-frequency stimulation of the subthalamic nucleus is a neurosurgical procedure for the alleviation of motor symptoms of Parkinson's disease and debilitating medication-induced dyskinesias. Stimulation is achieved with electrodes implanted stereotactically in the subthalamic nucleus by a neurosurgeon specializing in stereotactic surgery and a team(More)
