Bilateral globus pallidus stimulation for Huntington's disease
Annals of Neurology: Official Journal of the American Neurological …, 2004•Wiley Online Library
Bilateral globus pallidus internus (GPi) deep brain stimulation (DBS) was performed in a
patient with Huntington's disease (HD) with severe chorea. Stimulation at 40 and 130Hz
improved chorea. Stimulation at 130Hz slightly worsened bradykinesia overall, whereas
40Hz had little effect. A [15O] H2O positron emission tomography showed increased
regional cerebral blood flow in motor decision making and execution areas more evident at
40Hz. Adjustment of stimulation parameters in GPi DBS may have the potential to optimize …

Abstract
Bilateral globus pallidus internus (GPi) deep brain stimulation (DBS) was performed in a patient with Huntington's disease (HD) with severe chorea. Stimulation at 40 and 130Hz improved chorea. Stimulation at 130Hz slightly worsened bradykinesia overall, whereas 40Hz had little effect. A [15O] H2O positron emission tomography showed increased regional cerebral blood flow in motor decision making and execution areas more evident at 40Hz. Adjustment of stimulation parameters in GPi DBS may have the potential to optimize the motor response in HD, improving chorea without aggravating bradykinesia. Ann Neurol 2004
