Deep brain stimulation of the thalamus (thalamic DBS) is an established therapy for medically intractable essential tremor and tremor caused by multiple sclerosis. In both disorders, motor disability results from complex interaction between kinetic tremor and accompanying ataxia with voluntary movements. In clinical studies, the efficacy of thalamic DBS has(More)
We recorded resting-state neuronal activity from the human subthalamic nucleus (STN) during functional stereotactic surgeries. By inserting up to five parallel microelectrodes for single- or multiunit recordings and applying statistical spike-sorting methods, we were able to isolate a total of 351 single units in 65 patients with Parkinson's disease (PD)(More)
In addition to motor symptoms, patients with Parkinson's disease (PD) show deficits in sensory processing. These deficits are thought to result from deficient gating of sensory information due to basal ganglia dysfunction in PD. Deep brain stimulation of the subthalamic nucleus (STN-DBS) has been shown to improve sensory deficits in PD, e.g. STN-DBS(More)
Deep brain stimulation (DBS) of the posterior hypothalamus was found to be effective in the treatment of drug-resistant chronic cluster headache. We report the results of a multicentre case series of six patients with chronic cluster headache in whom a DBS in the posterior hypothalamus was performed. Electrodes were implanted stereotactically in the(More)
BACKGROUND The ventro-lateral thalamus is the stereotactic target of choice for severe intention tremor. Nevertheless, the optimal target area has remained controversial, and targeting of the subthalamic area has been suggested to be superior. PATIENTS AND METHODS Eleven patients with disabling intention tremor of different etiology (essential tremor (n =(More)
OFF-period dyskinesias have been reported as a consequence of fetal nigral transplantation for Parkinson's disease. This type of dyskinesias may appear in patients even in the prolonged absence of antiparkinson medication and be aggravated by levodopa. Therefore, pharmacological therapeutic approaches in these patients are limited. Here we report two(More)
Rarely, the postoperative management of patients with subthalamic deep brain stimulation (STN-DBS) is complicated by pharmacologically intractable dyskinesias. Here we report that in three of these patients additional stimulation of a proximal contact located within the subthalamic white matter may lead to a significant reduction of dyskinesias associated(More)
OBJECTIVE Deep brain stimulation (DBS) of the globus pallidus internus (GPi) is an effective treatment for medically refractory primary dystonia. We present our technique for direct preoperative visualization of the target using a fast spin-echo inversion-recovery (FSE-IR) sequence. METHODS Twenty-three consecutive patients (mean age 41 years, range 9-68(More)
BACKGROUND Thalamotomy was formerly used to treat different tremor syndromes. Nowadays, deep brain stimulation has become an established technique to treat -different movement disorders. The combination of these two stereotactic interventions is rare. CLINICAL PRESENTATION We present a patient in which a right-sided tremor -syndrome with an underlying(More)
