Filter by:Many patients with Parkinson's disease suffer of gait disorder termed as "freezing of gait" (FOG). non-pharmacological approach such as applying external cues is effective in mitigating FOG events. The aim of this study is to test the feasibility and patients satisfaction from a first stage of technology development, designed to deliver automatically external cues to the patients in their homes.
The study will examine the reciprocal relationships between the community, healthcare system, and personal determinants of self-management behaviors in persons with Parkinson's disease and their association with the performance of these behaviors in persons with Parkinson's Disease. In the first part of the study, data will be extracted from electronic medical records of 2500. In the second part of the study, a sub-sample of 200 participants with Parkinson's disease will be asked to answer standardized questionnaires.
The current research protocol aims at studying preparatory inhibition in two populations of patients suffering from movement disorders. First, in PART 1, we will work with Parkinson's disease (PD) patients to investigate the contribution of the basal ganglia in preparatory inhibition (Project 1 [P1] and Project 2 [P2]). Then, in PART 2, we will consider patients with focal hand dystonia (FHD), to test the hypothesis that altered muscle selectivity in this pathological condition is, at least in part, due to a lack of preparatory inhibition.
This is a randomized, single-blinded, triple crossover study focused on determining the feasibility of using transcranial magnetic stimulation (TMS) for treatment of Parkinson's disease related autonomic dysfunction and depression. Participants will undergo TMS to three brain regions: medial prefrontal cortex (mPFC) (experimental site), dorsolateral prefrontal cortex (DLPFC) (alternative experimental site), or primary sensory cortex (S1) (control site) in a triple crossover design. Participants will complete symptom questionnaires, neurologic examination and cognitive assessments, and orthostatic vital signs recording before and after each brain stimulation session.
It is not known what causes Parkinson's disease and what makes it worsen over time. Research conducted in the past few years has highlighted the possible role of inflammation on this process but its actual mechanisms are still obscure. In this study, the investigators aim to gain understanding on how inflammation is increased in Parkinson's disease and what are its mechanisms, by performing two Positron Emission Tomography (PET) scans using the tracer [11C]PBR28, that takes pictures of the brain highlighting the areas of inflammation, before and after the administration of a compound called Lipopolysaccharide or LPS, that is known to cause a mild degree of inflammation. The investigators will couple this study with two venous blood draws to measure the levels of circulating molecules of inflammation.
This project is a 3-month prospective study assessing the immediate and long-term changes associated with aerobic exercise in quality-of-life measures, nonmotor scores, brief neuropsychological batteries, and local field potentials (LFPs) in those with Parkinson's Disease (PD) who have undergone deep brain stimulation (DBS) surgery for management of their symptoms. In this study, the investigators will assess the feasibility of an aerobic exercise regimen in those with advanced PD and DBS, characterize the immediate and long-term changes in neuronal activity with exercise in PD, and assess the nonmotor impact of exercise in individuals with advanced PD and DBS. The investigators will recruit individuals who are not regular exercisers and develop an individualized 3-month exercise plan with the assistance of physical therapists, using heart rate targets for moderate exercise. Outcomes will be measured at baseline and following 3-months of regular exercise. Field potentials will be noted at baseline, during exercise every 2 weeks, and then a final baseline at the end of 3 months in on-medication and on-stimulation states. This will allow for characterization of field potential changes over time both during exercise as efficiency improves as well as impact on baseline neuronal activity in the resting state. This study is novel in that most aerobic exercise studies target early PD subjects and rarely include those who have undergone DBS surgery. The study will specifically focus on the feasibility of developing an aerobic exercise regimen in those with more advanced disease as well as gathering preliminary data on the impact it will have on motor and nonmotor features in this cohort. In addition to the clinical outcomes, investigators are now able to capture neuronal activity with novel FDA-approved DBS technology, allowing us to non-invasively monitor real-time changes in the basal ganglia in those who have undergone DBS surgery. This study will also aim to characterize baseline neuronal activity in this cohort and monitor for changes that occur during exercise as well as determine if there is a change in baseline neuronal activity as exercise tolerance improves and with consistent, regular aerobic exercise.
The aim of the study is to assess impact of Fecal Microbiota Transfer (FMT) on clinical symptoms of Parkinson's disease. Assesment of tremor, slowness of movements and balance problems before and after FMT will be performed. The effect of FMT on frequency of constipations, which are common among Parkinson disease patients and have negative impact on quality of life and drug absorption will also be assessed. Detailed assessment of absorption of levodopa, which is the golden standard of treatment of Parkinson disease, is planned. It is planned to recruit 40 patients with diagnosis of Parkinson disease and indications for colonoscopy (constipations, age >50 years). Patients will be randomly assigned to the group receiving treatment with FMT or identically looking placebo. It will be administered to intestine during colonoscopy. Patients will be assessed by neurologist few times after the procedure. Psychological assessment and examination of gait and balance by physiotherapist is also planned. The last assessment will be performed after 12 months to see if the clinical effect can be observed for such a long time. The composition of the intestinal microbiota will be carefully assessed before and after the procedure in order to identify pathogens that may affect the course of the disease.
Patients suffering from parkinsonism have respiratory function abnormalities. This study compared the effects of incentive spirometer and inspiratory muscle trainer on pulmonary functions in patients with parkinsonism.
Postural instability is one of the cardinal signs in Parkinson's disease (PD). It represents one of the most disabling symptoms in the advanced stages of the disease. It is associated with frequent falls and loss of independence. The aim of the current study is to assess the long term efficacy of high frequency repetitive transcranial magnetic stimulation (rTMS) on improving postural instability in PD patients.
Postoperative delirium (POD) is a common complication, and the incidence of POD after deep brain stimulation(DBS) implementation ranges from 10% to 40%. Previous studies suggested that aging and existing non-motor symptom were independent risk factors for POD after supratentorial tumor resections. Therefore, patients undergoing DBS are high-risk populations for POD. A lot of trials show that dexmedetomidine might help to reduce the incidence of delirium in patients undergoing non-cardiac surgery. However, the impact of dexmedetomidine on POD for patients undergoing DBS was seldom reported. The purpose of this study was to investigate the effect of dexmedetomidine on POD in patients with Parkinson' Disease undergoing DBS.
