Active clinical trials for "Parkinson Disease"

In certain neurosurgical procedures, the use of a stereotaxic frame is required. It is then possible to set a precise target (depending of the type of the surgery) to be reached by the surgeon. The fixation of the stereotactic frame on the awake patient's head is done under local anesthesia by screwing the frame directly into the skull. This procedure is reported as "painful" to "extremely painful" by patients. The objective of this study is to determine whether the hypnosis is effective in decreasing the pain perceived by the patient during the disposal of the stereotactic frame.

Balance and gait impairment increases the risk of falls and contributes to a reduced quality of life and shorter survival in Parkinson disease (PD) and atypical Parkinsonism patients. In preliminary case studies, electrical epidural spinal cord stimulation (SCS) has been shown to significantly improve gait, postural instability, rigidity, and tremor. Controlled studies for optimizing which stimulation settings produce the best clinical response for mobility and gait, and achieving these results chronically are all significant unmet needs. Using quantitative laboratory and mobile technologies to test a range of stimulation settings, this research study aims to determine which SCS parameters or combination of parameters is best suited to effectively alleviate disabling symptoms experienced by each patient.

Different conditions of gait ignition freezing, spontaneous freezing during walking and turning freezing on encountering obstacle will be investigated in fMRI study to examine whether different regions of brain will be involved under different conditions of freezing. We hypothesize that anterior cortical regions will engage in gait ignition failure, deep locomotion regions will be responsible for spontaneous freezing and schema regions will be involved in the generation of turning freezing on seeing the barrier. In the third part of the project, we will deliver a 5-day session of transcranial direct current stimulation (tDCS) to the motor cortex of the FOG patients to examine whether the intervention will benefit the patients. Based on the signal source findings, we will investigate whether the possible tDCS beneficial effect will be different or similar in patients with different electric sources. In addition, how long the possible beneficial effect of tDCS can be consolidated after the 5-day course of stimulation is crucial and requires to be elucidated under the research project. We aim to peep the myth of FOG in PD by the multi-modality approach and hope the study will benefit the long suffering patients.

Evaluation of the effectiveness of three different approaches for the rehabilitation of gait in patients with PD within a multidisciplinary, intensive rehabilitation treatment (MIRT).

The purpose of this study is to see the study drug, Mirabegron, is safe and effective in treating symptoms of Overactive Bladder in patients with Parkinson's disease.

The purpose of this study is to evaluate the impact of a non-invasive brain stimulation technique called transcranial magnetic stimulation (TMS) on voice/speech treatment in people with Parkinson's Disease (PD), through the use of speech and voice analysis, examination of voice box, and brain imaging methods.

This is a pilot study to evaluate the safety and efficacy of unilateral gamma knife subthalamotomy for Parkinson's disease in patients deemed poor candidates for deep brain stimulation.

The aims of the present study was to analyze the effect of consecutive sessions of Transcranial direct current stimulation associated to kinesiotherapy about gait performance of Parkinson' s disease. For this, the primary outcome was evaluation of gait performance by means of space and temporal parameters as speed (meter/second ), stride frequency (steps/min) and stride length (m). The secondary outcome is motor cortex excitability which is analyzed by means of single pulse transcranial magnetic stimulation (TMS) intends to determine: motor evoked potential amplitude (MEP) and rest motor threshold (rMT).

The purpose of this observational study is the long term follow-up of Parkinson's patients who participated in a clinical trial in which they received AAV-GAD gene transfer into the subthalamic nucleus (STN) region of the brain. Patients will be followed once a year for up to five (5) years. The study will monitor and evaluate the long term effects of AAV-GAD and provide long term safety information.

Among the psychiatric symptoms observed in the premotor phase of Parkinson's disease (PD) and/or in "de novo" patients, apathy is relatively frequent (estimated to 23%). However, the neuropathological bases of apathy are still unknown. However, recent data suggests that apathy could be linked to a more specific dopaminergic denervation in the ventral striatum. Rasagiline increases the bioavailability of striatal endogenous dopamine by blocking the MAO-B. Some recent data suggest rasagiline could be effective to improve apathy in Parkinson's disease. The primary outcome is to demonstrate a significant reduction of apathy using the Lille apathy rating scale (LARS) in drug naive patients with early diagnosed Parkinson's disease, using a treatment by rasagiline.
