Filter by:The purpose of this registry is to compile characteristics of world-wide outcomes for the use of Boston Scientific's commercially available Vercise DBS System in the treatment of Parkinson's disease. The utilization of Image Guided Programming (IGP), and other commercially available programming features, used as planning tools for the programming of patients with Boston Scientific's Vercise DBS System are also evaluated. Additionally, the utilization of the DBS Illumina 3D feature that may be used for the programming of patients with Boston Scientific's Vercise DBS Systems is also evaluated.
The overall aim of this observational study is to investigate the impact of COMT inhibition on homocysteine metabolism, vascular physiology and correlates of neurodegeneration in PD patients with certain COMT genotype. It is designed to evaluate effect size of Hcy lowering to secondary outcome parameters. Assessment of outcome parameters will be rater-blinded or computer-based.
Since droxidopa has been approved in Japan for treating freezing of gait in Parkinson's disease patients, this is to confirm and further investigate the safety and efficacy using a similar dose. The possible beneficial effects on cognition in mildly cognitively impaired Parkinson's disease patients will also be tested, since this problem in Parkinson's disease may be associated with decreased brain synthesis of norepinephrine (a neurotransmitter associated with multiple brain functions). During this 11 week study, droxidopa will be slowly titrated up to 600 mg daily. Walking and freezing of gait will be evaluated and rated. Cognitive functions will be evaluated by a computer-based program.
This study will compare the brain uptake of 18F- DTBZ in 20 patients with PD, 20 patients with MSA, 20 patients with PSP, 20 patients with CBS, and 20 patients with VaP, 20 patients with ET, and 10 patients with DT.
The purpose of this study is to characterize the pharmacokinetics (PK) of LY03003 following multiple escalating intramuscular injections, as compared to Neupro patch and to evaluate the safety and tolerability and preliminary efficacy of multiple ascending dose (MAD) of LY03003 following intramuscular injections.
The appearance of postural instability and gait disorders is a major turning point in the evolution of Parkinson's disease (PD). These axial symptoms are usually unresponsive to L-Dopa and represent a severe impairment for the patients due to frequent falls and reduced outside mobility. There is no effective pharmacological treatment available for these symptoms, and their pathophysiology is not well known : it is currently assumed that non-dopaminergic brainstem lesions participate to axial symptoms in PD. Surgically, these patients cannot benefit from high frequency deep brain stimulation (DBS) of the subthalamic nucleus (STN) since this operation tends to even aggravate axial symptoms unresponsive to L-Dopa in some patients. A dysfunction of the pedunculopontine nucleus (PPN) might be at the origin of these axial symptoms, since the PPN participates in the maintenance of posture and motion in primates. In PD patients, recent reports have suggested that low frequency stimulation of the PPN may equally improve gait and posture. However, these results are debatable due to methodological limitations, insufficient clinical evaluation and uncertain anatomical targeting. Thus, our aim is to propose a low frequency PPN stimulation to six advanced PD patients according to the usual criteria for STN DBS who are, however, unsuitable for this operation due to gait and posture disorders. We will perform a randomized, double-blind and cross over design (two months periods with and without DBS randomly assigned to each patient). The targeting will be allowed by a a three-dimensional and deformable atlas of the basal ganglia fusioned with the stereotaxic magnetic resonance imaging (MRI) of each patient. Evaluations will comprise 1 month before surgery and in "Off" and "On" stimulation condition: - clinical motor assessment in both "Off" and "On" drug state, including cardinal parkinsonian signs, gait and balance - gait initiation physiological evaluation - cognitive and behavioral testing If our hypothesis is confirmed, low frequency PPN stimulation may well represent a substantial improvement of our therapeutic options for advanced PD patients suffering from debilitating gait and posture disorders unresponsive to L-Dopa.
Freezing of gait (FOG) is a disabling episodic gait disturbance that is common among patients with Parkinson's disease (PD). The symptoms of PD generally show an asymmetric onset and progression. In particular, impairments in rhythmicity, symmetry, and bilateral coordination have been reported to be associated with FOG episodes. As the maintenance of gait depends on the precise alternating movements of both legs, irregularities in rhythm, symmetry, and bilateral coordination may impair gait sequence, potentially causing freezing. Results of recent studies strongly suggest that bilateral uncoordinated gait and marked gait asymmetry are associated with FOG. Moreover, it has recently been hypothesized that this may lead to a degree of asymmetric motor function, and that FOG in parkinsonian patients is triggered by a breakdown in the bilateral co-ordination underlying the normal timing of gait. Aim of the study was to evaluate how the modulation of asymmetry through physical therapy might improve gait and FOG.
Patients with Parkinson's disease (PD) will be trained using a cognitive behavioral group-training-program to reduce stress and augment quality of life. An unspecific group with the same amount and frequency of meetings is used as a control group. For the evaluation of the training effects, scales to assess quality of life, analyses of psychopathological variations as well as neurocognitive tests will be used. Protocol amendment in 1-2017: addition of FU year 3 and year 5.
The clinical utility of deep brain stimulation (DBS) for the treatment of movement disorders such as Parkinson's disease has been well established; however, there is a great disparity in outcomes among DBS recipients due to varied postoperative management, particularly concerning the choosing of an optimal set of programming parameters from the thousands of possible combinations. This study will evaluate the use of motion sensor based assessments to develop a functional map and algorithms to automatically determine a set of programming parameters that maximize symptomatic benefits while minimizing side effects and battery consumption.
This is a Phase I clinical trial of the FDA approved drug Glycerol Phenylbutyrate to see if phenylbutyrate can increase the removal of alpha-synuclein from the brain into the bloodstream. Alpha-synuclein forms abnormal protein deposits in dopamine neurons and is believed to cause the death of brain cells, leading to Parkinson's Disease.
