OBJECT Deep brain stimulation (DBS) of the globus pallidus internus (GPI) is a promising new procedure for the treatment of dystonia. The authors describe their technical approach for placing electrodes into the GPI in awake patients with dystonia, including methodology for electrophysiological mapping of the GPI in the dystonic state, clinical outcomes and(More)
The following experiments investigated the behavioral response to local microinfusion of dopamine (DA) and selective DA agonists into the core and shell subregions of the nucleus accumbens. Rats were implanted with chronic indwelling cannulae aimed at these subregions. Two experiments were conducted. In experiment 1, the response to DA (0, 2, 5, 10(More)
Idiopathic cranial-cervical dystonia (ICCD) is an adult-onset dystonia syndrome affecting orbicularis oculi, facial, oromandibular, and cervical musculature. ICCD is frequently difficult to treat medically. Deep brain stimulation (DBS) of the globus pallidus internus (GPi) is a highly effective treatment for idiopathic generalized dystonia, however less is(More)
BACKGROUND The results from thalamic deep brain stimulation (DBS) for atypical tremor syndromes including tremor from multiple sclerosis (MS) and stroke are often disappointing. Three recent case reports have suggested that simultaneous stimulation of multiple thalamic targets can result in sustained improvement in such cases. METHODS We analyzed the(More)
OBJECTIVES The globus pallidus internus (GPi) has been the primary target for deep brain stimulation (DBS) to treat severe medication-refractory dystonia. Some patients with primary cervical or segmental dystonia develop subtle bradykinesia occurring in previously nondystonic body regions during GPi DBS. Subthalamic nucleus (STN) DBS may provide an(More)
BACKGROUND Deep brain stimulator (DBS) implantation has been shown to be effective in the treatment of various movement disorders including Parkinson's disease, essential tremor and dystonia. However, there is limited information regarding the potential use of DBS in Huntington's disease (HD). In this study, the authors present their findings on the(More)
Chorea is the predominant motor manifestation in the early symptomatic phase of adult onset Huntington's disease (HD). Pathologically, this stage is marked by differential loss of striatal neurons contributing to the indirect pathway. This pattern of neuronal loss predicts decreased neuronal firing rates in GPi and increased firing rates in GPe, the(More)
This paper presents a discrete-event simulation model used to explore various possibilities for improving the training continuum at the Marine Corps Communication-Electronics School. The goal of the analysis is to reduce the average waiting time experienced by Marines as they wait for their formal training to commence. Results show that the implementation(More)
BACKGROUND Subthalamic nucleus deep brain stimulation (DBS) is an alternative target choice for treating primary dystonia, but little is known about the most effective programming parameters. OBJECTIVE Here we prospectively evaluate the effect of low versus high frequency subthalamic nucleus DBS in patients with predominantly cervical or upper extremity(More)
Deep brain stimulation (DBS) has developed into an important therapy for Parkinson disease, essential tremor, and dystonia with more nurses in varied settings often preparing patients and families for this type of surgery. This exploratory study sought to obtain patient and caregiver perspectives of the current DBS teaching for Parkinson disease, essential(More)
