OBJECTIVE To investigate the effects of unilateral deep brain stimulation (DBS) in the right nucleus accumbens in patients with obsessive-compulsive disorder (OCD). Predominantly bilateral stimulation of the anterior limb of the internal capsule was utilized. METHODS The study was designed as a double-blind sham-controlled crossover study. Patients(More)
BACKGROUND A prospective study was conducted to assess the efficacy and side effects of linear accelerator (LINAC)-based radiosurgery (RS) performed with a reduced dose of therapeutic radiation for patients with surgically inaccessible pituitary macroadenomas. METHODS From August 1990 through January 2004, 175 patients with pituitary macroadenomas were(More)
OBJECTIVE To determine the surgery-related and hardware-related complications of deep-brain stimulation (DBS) at a single centre. METHODS 262 consecutive patients (472 electrodes) operated for DBS in our department from February 1996 to March 2003 were retrospectively analysed to document acute adverse events (30 days postoperatively). The data of 180 of(More)
Objective.  Deep brain stimulation (DBS) increasingly attracts attention as a potential treatment of mental disorders. Beside depression and obsessive-compulsive disorders, DBS has already been shown to be beneficial for Tourette syndrome (TS). Clinical Presentation/Method.  The authors report on the outcome of a patient with treatment-resistant TS who(More)
BACKGROUND Brain metastases represent the most common intracranial tumors and are associated with very poor prognosis. OBJECTIVE To investigate the feasibility, survival, and cerebral disease control of patients with singular brain metastases treated with stereotactic 125iodine brachytherapy (SBT), to identify prognostic factors, and to compare results(More)
To study the dynamical mechanism which generates Parkinsonian resting tremor, we apply coupling directionality analysis to local field potentials (LFP) and accelerometer signals recorded in an ensemble of 48 tremor epochs in four Parkinsonian patients with depth electrodes implanted in the ventro-intermediate nucleus of the thalamus (VIM) or the subthalmic(More)
BACKGROUND The optimal management of subtotally resected or recurrent malignant meningiomas remains controversial. We evaluated the efficacy of linear accelerator (LINAC) radiosurgery for atypical and anaplastic meningiomas after incomplete resection or treatment of recurrences. METHODS Between August 1990 and December 2003, 16 patients with 28(More)
BACKGROUND AND PURPOSE For patients with inoperable brain metastases, whole brain radiotherapy (WBRT) has been the standard treatment for decades. Radiosurgery is an effective alternative strategy, but has failed to show a substantial survival benefit so far. The prognostic factors derived from the RTOG recursive partitioning analysis (RPA) provide a(More)
OBJECTIVE To investigate in patients with essential tremor (ET) treated with thalamic/subthalamic deep brain stimulation (DBS) whether stimulation-induced dysarthria (SID) can be diminished by individualized current-shaping with interleaving stimulation (cs-ILS) while maintaining tremor suppression (TS). METHODS Of 26 patients screened, 10 reported SID(More)
Cholinergic neurons of the medial forebrain are considered important contributors to brain plasticity and neuromodulation. A reduction of cholinergic innervation can lead to pathophysiological changes of neurotransmission and is observed in Alzheimer's disease. Here we report on six patients with mild to moderate Alzheimer's disease (AD) treated with(More)
