Filter by:The purpose of this study is to evaluate the added value of PET-CT with [18F]FDOPA tracer for Assessment of the Myocardial Sympathetic Denervation in patients with or suspected with Parkinson's disease. The investigators expect to see normal values of uptake ratio of [18F]FDOPA , in patients with no synuclein underline pathology or previously known cardiovascular disease (no history of high blood pressure or take medications that influence the sympathetic system- exclusion criteria). Low values of uptake ratio is presumed to be found in patients diagnosed with Parkinson's disease or other synuclein pathology. The expected normal ratio of Heart/liver uptake values will be determined from scans of patients refered to [18F]FDOPA scan and were found to have normal [18F]FDOPA scan of the basal ganglia and no cardiovascular diseases.
The scientific aim of this study is to investigate the efficacy and safety of incobotulinumtoxinA (Xeomin-Merz Pharmaceuticals) in the tremor of Parkinson‟s disease. Our hypothesis is that injection of Xeomin into the muscles of arm, forearm and hand decreases the tremor amplitude and frequency leading to improvement of the patient‟s function.
Subjects diagnosed with Idiopathic Parkinson's Disease, between ages of 40-85 inclusive, who have been referred for gait training. Since there can be subtle differences in the brain organization of left- and right-handed people that may influence some of the measurements, right handed participants are preferred. However, a left handed participant may be considered. Participants will be randomly assigned to one of two groups to undergo two weeks of twice-daily sessions. Group A receiving goggles fitted with lenses that distort vision and Group B patients receiving sham goggles
Single-centre, open-label, randomised, three-part, two-way crossover study in 84 healthy volunteers. In each part, the study consisted of two consecutive single-dose treatment periods separated by a washout period of at least 14 days.
- To characterize physiological biomarkers of positive response to rDTMS using EEG and functional MRI (fMRI) in patients with PD. - To develop a set-up and algorithm for neurophysiological monitoring for PD patients using EEG and fMRI in patients treated by rDTMS. - To integrate rDTMS stimulation with monitoring techniques with the ultimate goal of providing closed-loop feedback where monitoring informs the stimulation
This study is designed to evaluate the high-frequency range deep brain oscillations (HFO) as pathologic markers in patients undergoing deep brain stimulation for epilepsy or Parkinson disease. Newly developed technology allows for the chronic recording of these brain signals at the same time as clinical stimulation is occuring. We will learn both whether these HFO correlate with disease activity and whether the HFO change in response to ongoing stimulation (potentially giving insight into the underlying mechanism of action of DBS).
The objectives of this study were to characterize the effects of food on the pharmacokinetics (PK) and tolerability of BIA 9-1067 in healthy male subjects.
The investigators conducted an intervention based in proprioceptive exercises and balance tasks. The investigators also carried out a brief intervention in manual dexterity. The study hypothesis is that a brief intervention in upper extremities and a exercise program can increase functionality in Parkinson.
The proposed randomized controlled trial will evaluate the effects of treadmill training augmented with virtual reality on fall risk. 300 older adults with a history of falls will be recruited to participate in this study. This will include older adults (n=100), patients with mild cognitive impairment (MCI) (n=100), and patients with Parkinson's disease (PD)(n=100). Subjects will be randomly assigned to the intervention group (treadmill training with virtual reality) or to the active-control group (treadmill training without virtual reality). Each person will participate in a training program set in an outpatient setting 3 times per week for 6 weeks. Assessments will take place before, after, and 1 month and 6 months after the completion of the training.
The role of the basal ganglia in the processing of information with emotional or motivational content has been demonstrated by several lesion and functional imaging studies in humans and animals. Deep brain stimulation surgery provides an opportunity to study these structures in humans in electrophysiological terms. The aim of this study is to investigate modifications in the electrophysiological activity of the subthalamic nucleus (STN) during the perception of auditory and visual stimuli with emotional or motivational connotations in patients with Parkinson's disease who have just undergone implantation of a deep brain stimulator in the STN.
