Filter by:The aim of this study is to assess the safety and the potential efficacy of personalized Local Field Potential (LFP)-based adaptive Deep Brain Stimulation (aDBS), using the implantable pulse generator (IPG) of the "AlphaDBS" System, in Parkinson's Disease patients, chronically implanted in subthalamic nucleus (STN) for DBS, at the time of IPG replacement.
Single site observational study focused on elucidating the genes and biochemical pathways involved in causing Parkinson disease.
The aim of the project is to evaluate disease progression of patients with Parkinsonian syndrome of various severity through regular home-based gait parameters analysis. We identified several steps in this project: 1. Acquisition of gait data in 120 patients with Parkinsonism at different stages in hospital and ecological condition (during 10 days at home), in a repetitive manner: 1. 30 Early PD patients, before 3 years of disease duration (MDS criteria, 2018) 2. 30 PD patients with motor fluctuations (5 to 8 years of disease duration) (MDS criteria, 2018) 3. 30 PD patients with FoG (10 years of disease duration) (MDS criteria, 2018) 4. 30 patients with MSA (less than 5 years after the first symptom) 2. Control groups will be composed by 30 healthy volunteers Correlation analysis with clinical measurements and biomarkers, namely blood biomarkers for neurodegeneration (4HN, NFLT …) and multimodal MRI repeated assessments (Iron overload, inflammation and degeneration) and genetic panel for common haplotypes involved in Parkinsonism.
The study is designed to assess the effects of cardiovascular (aerobic) exercise on motor skill learning in Parkinson patients. Specifically, the investigators examine whether moderate-intense aerobic exercise, performed immediately following motor skill practice over the course of a six week intervention period, facilitates motor memory consolidation. In this experimental trial, participants will be randomly allocated to either an intervention group (motor skill practice + aerobic exercise) or control group (motor skill practice + seated rest).
Deep brain stimulation (DBS) in the dorsal region of the subthalamic nucleus (STN) is very effective for reducing motor symptoms of Parkinson's disease (PD). Modeling studies suggest that this therapy may result in current spread into the ventral STN, causing altered cognitive processes. As a result, current stimulation parameters often lead to worsening in verbal fluency, executive function, and, particularly, cognitive control. There is evidence suggesting that low frequency oscillatory activity occurs across brain circuits important in integrating information for cognition. Preclinical studies and human recording studies indicate these low frequency theta oscillations drive cognitive control during cognitive tasks. Thus, the purpose of this study is to determine the safety, tolerability, and efficacy of low frequency stimulation (LFS) of the ventral STN alongside standard high frequency stimulation (HFS) of the dorsal STN in patients with PD.
The present study is a proof-of-concept clinical trial to test the efficacy of low doses of a repurposed anti-epileptic drug (levetiracetam) in treating memory problems in Parkinson's disease (PD). Neuroimaging techniques will be used to determine the effect of the drug on specific brain regions (hippocampal subfields). Finally, baseline brain activity of PD patients with memory problems will be compared to PD patients without memory problems and healthy older adults to determine if activity in specific brain regions (hippocampal subfields) can be used to predict memory problems in PD. This information will be useful for future clinical trials to target drugs to these brain regions.
Walking on a split-belt treadmill (each of the two belts running at a different speed) imposes an asymmetrical gait, mimicking limping that has been observed in various pathologic conditions. This walking modality has been proposed as an experimental paradigm to investigate the flexibility of the neural control of gait and as a form of therapeutic exercise for hemi-paretic patients. However, the scarcity of dynamic investigations both for segmental aspects and for the entire body system, represented by the centre of mass, challenges the validity of the available findings on split gait. Compared with overground gait in hemiplegia, split gait entails an opposite spatial and dynamic asymmetry. The faster leg mimics the paretic limb temporally, but the unimpaired limb from the spatial and dynamic point of view. These differences suggest that a partial shift in perspective may help to clarify the potential of the split gait as a rehabilitation tool. The aim of the present study is to investigate the dynamic asymmetries of lower limbs in adults with unilateral motor impairments (e.g. hemiplegia post-stroke, Parkinson's disease, multiple sclerosis, unilateral amputation, surgical orthopedic interventions) during adaptation to gait on a split-belt treadmill. The sagittal power provided by the ankle and the total mechanical energy of the centre of mass will be thoroughly studied. The time course of phenomena both during gait when the belts are running at different speed and when the belts are set back to the same speed (i.e. the after-effect) will be investigated. A greater dynamic symmetry between the lower limbs is expected after split gait. The question whether this symmetry will occur when the pathological limb is on the faster or the lower belt will be disclosed. Some alterations of the motion of the centre of mass during split gait are also expected.
The project intends to assess the polygenic burden of rare disruptive mutations in Parkinson's disease (PD) and how they influence the phenotype/pathological heterogeneity of disease.
The purpose of this study is to learn more about the effects of abdominal compression and the medication midodrine, two interventions used for the treatment of orthostatic hypotension (low blood pressure on standing), on hemodynamic markers of cardiovascular risk. The study will be conducted at the Vanderbilt University Medical Center and consists of a screening and 2 testing days, one with abdominal compression and one with midodrine. The total length of the study will be about 5 days.
In this study, it is aimed to investigate the effect of Pilates application on abdominal muscle function, core stability, musculoskeletal pain, quality of life, anxiety and depression in Parkinson's Patients.
