Filter by:This study will examine the effects of lithium aspartate 30-45mg/day on MRI biomarkers and blood-based therapeutic targets among 15 early-stage Parkinson's disease patients.
The overall goal of the proposed research is to evaluate the use of [11C]SY08 as a PET radiotracer for aggregated alpha synuclein (αS) in individuals with Parkinson's disease (PD), Multiple system atrophy (MSA), Dementia with Lewy Bodies (DLB) and healthy controls. The purpose of this study is to evaluate the use of [11C]SY08 as a PET radiotracer for αS fibrils in individuals with PD, MSA, DLB and healthy controls. The specific aims of the current study are: 1. To determine brain uptake, distribution, and kinetics of [11C]SY08 in healthy individuals. 2. To determine brain uptake, distribution, and kinetics of [11C]SY08 in patients with alpha synuclein aggregates in the brain, including PD, DLB and MSA. 3. To determine human dosimetry of [11C]SY08 in healthy individuals An intravenous bolus injection of [11C]SY08 will be administered per subject for brain PET imaging.
The research will evaluate possible clinical and individual brain topographic features affecting the outcome in subthalamic deep brain stimulation (DBS) with patients with Parkinson's disease (PD). The patient cohort consists 35 PD patients treated with subthalamic DBS in 2020-2022. The clinical features (such as age, disease duration, response to levodopa in the levodopa challenge test) will be evaluated retrospectively from the medical records and brain topographic features from the preoperative 3 Tesla brain imaging.
Freezing of gait is a symptom of Parkinson's disease (PD) that becomes more evident with the evolution of the disease, and which presents an important difference compared to the other signs and symptoms: does not respond adequately to dopaminergic therapy, which calls into question its pathophysiology. In this sense, and through empirical experience, it has been noted that freezing responds to cueing techniques (visual, sensory motor, auditory tricks, among others) which suggests a similarity with dystonic pathology. This similarity could be the basis of a common response to botulinum toxin (BT). Objectives: This study aims to understand whether BT is an effective therapy for freezing gait in patients with Parkinson's disease. Methodology: This is a prospective parallel study with therapeutic intervention, controlled by placebo, double blind. The randomization of groups will be stratified. The population will be recruited from from the CHLC movement disorders consultation, and that meets the following inclusion criteria: Parkinson's disease with freezing of gait, scoring > 1 at point 2.13 on the scale MDS-UPDRS and be responsive to cueing techniques, with severity of Parkinson's disease rated 3 or 4 on the Hoehn & Yahr scale. The BT injection will be performed by a doctor with experience in this therapy, with 100 Units (U) of type A BT, bilaterally, in the flexor muscle of the thigh, once, with replacement of the same ampoules with saline in controls. To the Patient assessments will take place over 4 months, weekly by telephone using a questionnaires on freezing and the notion of clinical improvement (FOGQ and SCGIC, respectively) and monthly in person with objective assessments using the MDS-UPDRS scales - part III motor assessment, Timed Up & Go and Two Minute Walk.
The research team aims to provide evidence of Parkinsonian (PD) Stutter management by addressing the primary neurological issue in this disorder using Deep Brain Stimulation (DBS). The team proposes to perform unilateral DBS on 3 patients with PD stutter refractory to intensive speech therapy, to determine a response in their PD stutter. The assessments will be double-blinded. The investigators will use the outcome of this case series to determine the feasibility and details of a larger randomized controlled trial.
The goal of this clinical trial is to learn about the application of domestic PET/MR in major brain diseases. The main questions it aims to answer are: - Overcome the bottleneck of early accurate diagnosis and treatment in major brain diseases clinical practice. - Promote the clinical application of domestic PET/MR, enhance international competitiveness. Participants will have a PET/MR scan of the brain.
OBJECTIVE: The aims of this study were to assess the incidence rate and risk factors for sialorrhea in the long-term follow-up in a cohort of 170 patients with advanced Parkinson's disease [84 with deep brain stimulation (DBS) and 86 on medical treatment]. Design, setting, and participants: This study was a multi-center prospective non-randomized concurrent clinical trial. A total of198 persons with Parkinson disease were referred for DBS between June 2019 and July 2021 and analyzed between June 2023 and July 2023.The primary outcome follow-up visit was conducted 36 months after DBS.
This study intends to apply structural and functional brain network neuroimaging techniques combined with image post-processing methods to explore the differences in brain network changes in PD patients with cognitive impairment after DBS or TMS.
Transcranial Ultrasound Stimulation (TUS) is an emerging non-invasive brain stimulation(NIBS) technique that can be used on both superficial and deep brain targets with a high spatial resolution as small as a few cubic millimeters. Functional Electrical stimulation is a peripheral stimulation technique researched and clinically used to restore motor function following conditions like stroke and Spinal cord injury. To date, there are no studies that have looked at the neuro modulatory effects of combining TUS and FES on motor symptoms in patients with Parkinson's disease. The current study aims to understand the neuromodulatory effects of combining tbFUS to bilateral primary motor cortex (M1) in Parkinsons's disease patients immediately followed by bilateral upper extremity FES of the hand muscles for improving motor symptoms.
Veterans with mid to later stage Parkinson's disease (PD) may not be able to work out as hard as they need to, to prevent brain cell loss. Maybe they could work out longer and more frequently to make up for this during their good times and good weeks and then rest during the bad weeks. The investigators will compare how effective working out a lot one week per month with a break of three weeks is to continuously exercising weekly with no breaks in people with mid stage PD. The investigators will look at how fast participants walk per minute, whether they become more physically active, the biochemicals in their blood, and at how stiff their blood vessels are before and after the exercise.
