Filter by:The aim of this project is to improve biological collections of patients presenting rare neurological disorders with known or suspected autoimmune origin. This collection will provide appropriate biological samples to identify new biomarkers and to be accessible to the medical, scientific and industrial communities for the identification of new therapeutic strategies.
Parkinson's disease (PD) is the second most common neurodegenerative disease. The cardinal symptoms of PD are tremor, rigidity, bradykinesia and postural instability. Gait disturbance is also one of the key features of PD. At present, the mainstream treatment of PD is the dopaminergic supplement. However, the response to the medical treatment varies between symptoms. Rigidity and bradykinesia respond to the medical treatment the best, and tremor respond partially. Gait disorders do not usually respond to the dopaminergic medication. Freezing of gait (FOG) is one of the most notorious and devastating presentation of gait disorders in PD. Currently, there is no available treatment for FOG, even the invasive deep brain stimulation does not work on it. Repetitive transcortical magnetic stimulation (rTMS) is a novel non-invasive intervention. Through the magnetic stimulation, brain neurons could be activated by the electrical current. The application of rTMS had been approved by US FDA for the treatment of depression. The possible effect of rTMS may result from the stimulation-related neuronal plasticity. Regarding PD, rTMS also had been found to had some effect on different motor symptoms, mainly on the bradykinesia and rigidity but not gait. The present study would like to test the accumulative effect of rTMS on gait disorders of PD, especially the phenomenon of FOG. All the study subjects will receive rTMS under intermittent theta burst stimulation (iTBS) mode at supplementary motor area (SMA). Gait analysis and other motor performance will be assessed before and after the intervention.
The pilot study was performed to evaluate the usability, credibility and expectancy of an intelligent, activity-based client-centred training system (i-ACT), and the motivation towards its use in neurological rehabilitation over a short period of time.
This multi-arm, multi-site study investigates the safety, tolerability, and efficacy of stem cell therapy for the treatment of various acute and chronic conditions. Clinically observed initial findings and an extensive body of research indicate regenerative treatments are both safe and effective for the treatment of multiple conditions.
Our project is based on the fundamental hypothesis that epidural spinal cord stimulation (SCS) improves Freezing of gait (FOG) in patients with Parkinson's disease. In eight patients implantation of electrodes for SCS at the epidural thoracic level will be performed under general anaesthesia. Evaluation of gait and motor symptoms will be performed with and without stimulation, after a 3-month period for each of the stimulation conditions.This is a pilot, single centre, prospective, randomized, double blinded, cross-over study.
Background: Recent reports increasingly recognize neurological manifestations in COVID-19 patients. However, the full spectrum of the disease and risk factors are not well understood. Aim: To describe the full spectrum of neurological manifestations in COVID-19 and assess the clinical characteristics, risks and prognostic factors. Outcomes: Identification of COVID-19 associated neurological disease is the primary outcome while requirement for admission to critical care unit, mortality, length of hospital stay, quality of life, and neurological disability are the secondary outcomes. Participants: Patients above Age more than 18 years enrolled based on new-onset acute neurological disease and COVID19 positive will serve as cases while patient with confirmed COVID-19 without neurological manifestation will serve as controls. Design and Procedures: The study is prospective case control in design and is divided into three phases in India, Brazil and Malawi ; the first phase will address role of hypoxia in causation of neurological diseases, the second phase will compare characteristics of patients hospitalized with COVID-19 with and without neurological disease and the third phase will assess the long-term follow up (at 3 months and 9 months) of cases.
Functional neurological disorders are an important subgroup of patients with stroke mimics admitted to stroke unit.Their clinical profile and outcome are poorly known. The goal of this study is to describe the cognitive and behavioral profile of stroke mimics patients, without evidence of neurological disease.
The main goals of this study are to further determine whether the study drug donanemab is safe and effective in participants with Alzheimer's disease and to validate video scale assessments.
To investigate the potential antiseizure effects of adjunctive XEN496 (ezogabine) compared with placebo in children with KCNQ2 Developmental and Epileptic Encephalopathy (KCNQ2-DEE).
The purpose of this study is to determine the feasibility of producing artificial vision in persons with blindness. Study participants will have wireless electrical stimulators implanted into the cortical vision processing areas of their brains. The ability of the participants to perceive artificial vision in response to electrical stimulation will be assessed.
