BACKGROUND Patients with advanced Parkinson's disease often have rapid swings between mobility and immobility, and many respond unsatisfactorily to adjustments in pharmacological treatment. We assessed whether globus pallidus pars interna (GPi) deep brain stimulation (DBS) gives greater functional improvement than does subthalamic nucleus (STN) DBS. (More)
OBJECTIVE To assess the neuropsychological outcome 12 months after bilateral deep brain stimulation (DBS) of the globus pallidus pars interna (GPi) or subthalamic nucleus (STN) for advanced Parkinson disease. METHODS We randomly assigned patients to receive either GPi DBS or STN DBS. Standardized neuropsychological tests were performed at baseline and(More)
OBJECTIVE To compare motor symptoms, cognition, mood, and behavior 3 years after deep brain stimulation (DBS) of the globus pallidus pars interna (GPi) and subthalamic nucleus (STN) in advanced Parkinson disease (PD). METHODS Patients with PD eligible for DBS were randomized to bilateral GPi DBS and bilateral STN DBS (1:1). The primary outcome measures(More)
Parkinson's disease (PD) is a neurodegenerative disorder characterised by tremor, rigidity and bradykinesia. The current treatment, for example with levodopa or dopamine-agonists, is complicated by response fluctuations, dyskinesias and gastro-intestinal side-effects. These, and various other reasons including fear of levodopa toxicity, have led to(More)
BACKGROUND The aim of this study was to assess psychiatric and social outcome 12 months after bilateral deep brain stimulation (DBS) of the globus pallidus pars interna (GPi) and subthalamic nucleus (STN) for advanced Parkinson's disease (PD). METHODS We randomly assigned patients to receive GPi DBS (n = 65) or STN DBS (n = 63). Standardized psychiatric(More)
In 2 unrelated patients with axial hypotonia, developmental delay and a hyperkinetic movement disorder, a missense mutation was found in codon 209 of the GNAO1 gene. From the still scarce literature on GNAO1 mutations, a clear genotype-phenotype correlation emerged. From the 26 patients reported thus far, 12 patients had epileptic encephalopathy, and 14 had(More)
Orthostatic tremor (OT) is characterized by progressive unsteadiness during stance, due to fine-amplitude leg tremor with a 13e18 Hz frequency, leading to limited ability to stand or walk and impaired functioning. Medication is often ineffective. Bilateral deep brain stimulation (DBS) of the thalamic nucleus ventralis intermedius medialis (Vim) has been(More)
OBJECTIVE Deep brain stimulation (DBS) is effective in the management of patients with advanced Parkinson's disease (PD). While both the globus pallidus pars interna (GPi) and the subthalamic nucleus (STN) are accepted targets, their relative efficacy in randomized controlled trials (RCTs) has not been established beyond 12 months. The objective of this(More)
BACKGROUND Effects on non-motor symptoms, mainly cognitive and psychiatric side effects, could influence the decision for either globus pallidus pars interna (GPi) or subthalamic nucleus (STN) deep brain stimulation (DBS) for patients with Parkinson's disease (PD). OBJECTIVE 1) To compare cognitive and psychiatric outcomes 3 years after GPi DBS versus STN(More)
