The goal of this clinical trial is to investigate the feasibility if a remotely administered smartphone app can increase the volume and intensity of physical activity in daily life in patients with isolated Rapid Eye Movement (REM) sleep behaviour disorder over a long period of time (24 months). Participants will be tasked to achieve an incremental increase of daily steps (volume) and amount of minutes exercised at a certain heart rate (intensity) with respect to their own baseline level. Motivation with regards to physical activity will entirely be communicated through the study specific Slow Speed smartphone app. Primary outcomes will be compliance expressed as longitudinal change in digital measures of physical activity (step count) measured using a Fitbit smartwatch. Exploratory outcomes entail retention rate, completeness of remote digital biomarker assessments, digital prodromal motor and non-motor features of PD, blood biomarkers and brain imaging markers. Using these biomarkers, we aim to develop a composite score (prodromal load score) to estimate the total prodromal load. An international exercise study with fellow researchers in the United States and United Kingdom are currently in preparation (Slow-SPEED). Our intention is to analyse overlapping outcomes combined where possible through a meta-analysis plan, to obtain insight on (determinants of) heterogeneity in compliance and possible efficacy across subgroups
Determining the efficacy of the BIS monitor in monitoring deep hypnotic states as well as intra- and post-operative outcomes in neurosurgery patients
Neuralis is an innovative assistive technology designed for individuals with severe neuromuscular conditions, enabling wheelchair control through EEG signals. This study aims to assess the safety, feasibility, and efficacy of Neuralis in restoring mobility and independence. The device is a discreet EEG headset which specializes in decoding signals from visual cortex, allowing users to initiate precise wheelchair movements through focused attention. This research seeks to demonstrate Neuralis' potential in revolutionizing assistive technology by offering a non-invasive, user-friendly solution for individuals facing motor impairments, ultimately enhancing their quality of life.
Background: Immune system and nervous system have significant interaction so that People with immunity diseases can have complications that affect the nervous system and people with some neurological disease may have defects in their immune system.These complications can affect many body functions, including how they move, walk, think, and feel. Researchers do not fully understand how immune diseases affect the nervous system. By learning more, they hope to create more effective treatments. Objective: To learn more about the interaction between immune and nervous system and how immunity disease affect the nervous system. Eligibility: People aged 2 years and older with an immunity disease. Their healthy biological relatives and other healthy volunteers are also needed. Design: Participants will be screened. Blood will be drawn for research. They may have imaging scans. Adults may undergo lumbar puncture: A needle will be inserted into their back to collect fluid from the space around the spinal cord. The imaging scans and lumbar puncture will be optional for healthy relatives and volunteers. All participants will have 1 study visit per year for 5 years. They will be asked to donate samples of body fluids at each visit. Blood samples are required for the study. All other donations are optional. These may include saliva, urine, breast milk, stool, vaginal secretions, and wound drainage. Affected participants may be asked for a skin biopsy: A small sample of skin will be removed. They may also be photographed or videotaped to record the symptoms of their disease. Tests for each study visit may be spread over several days, if needed. Visits may be at the clinic. Participants may also collect their own samples at home and send them to the researchers....
Functional neurological disorders (FND) are motor, sensory or cognitive symptoms without an identified lesion. This is a very common reason for consultation in neurology. Transcranial magnetic stimulation (TMS) may be performed in these patients both for diagnostic purposes (in the context of motor evoked potentials) and for therapeutic purposes. The main objective of the study is to evaluate tolerability of TMS in patients with FND, in particular the pain caused by stimulation and the possible modification of painful or non-painful symptoms generated by this TMS. The secondary objectives are to assess chronic pain symptoms of these patients quantitatively and qualitatively, to assess expectations of these patients with regard to the performed examinations and to assess their expectations regarding magnetic stimulation performed for therapeutic purposes.
Individuals who come to the neurology clinic to undergo lumbar puncture, and meet the inclusion criteria, and agree to participate in the study will be given a stress ball during the procedure and will be asked to squeeze this ball.
Handheld optical coherence tomography (OCT) has become an important imaging modality to evaluate the pediatric retina. The objective of this pilot study is to compare a new contact OCT system (Theia Imaging) with an investigational noncontact OCT system (Duke Biomedical Engineering) to assess their ability to image the pediatric retina. The investigators hypothesize that the contact OCT system is superior in imaging larger areas of the retina (larger field-of-view), while it has similar resolution to image the retina substructures (non-inferior image quality).
The investigators recently identified Brain-derived tau (BD-tau) as a sensitive blood-based biomarker for brain injury in acute ischemic stroke: in patients with acute ischemic stroke, plasma BD-tau was associated with imaging-based metrics of brain injury upon admission, increased within the first 24 hours in correlation with infarct progression, and at 24 hours was superior to final infarct volume in predicting 90-day functional outcome. While informing on the relation of BD-tau with imaging-based metrics of brain injury, this cross-sectional study was restricted to BD-tau assessments upon admission and at day 2 and could not inform on key characteristics of the evolution of plasma BD-tau, including when exactly it starts to rise, how long it continues to rise, and how it is determined by infarct characteristics as well as comorbidities. Here, the investigators aim to assess plasma BD-tau every hour from admission to 48 hours after onset to evaluate the hypothesis that BD-tau rises immediately after onset and plateaus between three and 48 hours after onset.
Research purpose Using single-cell sequencing, 3D/4D genomics and multidimensional omics technologies to reveal the complex cellular and molecular regulatory networks of cardiovascular and nervous system diseases, unique phenotypic changes of specific cell types, and different gene expression patterns, identify cell types and cell subsets associated with cardiovascular and nervous system diseases, and discover disease-related genes. To reveal new pathological mechanisms of related diseases and develop new diagnosis and treatment methods. Research background Cardiovascular and nervous system diseases such as arrhythmias (atrial fibrillation, ventricular tachycardia, ventricular fibrillation, postoperative vascular stenosis injury, etc.), heart failure, atherosclerosis (coronary heart disease, stroke, peripheral vascular disease, carotid atherosclerosis, etc.), epilepsy, moyamoya disease, etc., are currently leading to the main diseases affecting the health and death of residents in China. The data integration method based on single-cell sequencing, multi-omics data, and machine learning to analyze molecular level changes in cardiovascular and nervous system-related diseases can help deepen the research on the pathogenesis of cardiovascular and nervous system-related diseases and provide new ideas for the prevention and treatment of related diseases.
