Filter by:To investigate multimodel MRI exploring the pathophysiology of multiple sclerosis and neuromyelitis optica spectrum disorders. The investigators use multimodel MRI to evaluate the extent of blood-brain barrier and white matter fiber tracts destruction , iron deposition and cerebral blood flow of associated regions in multiple sclerosis and neuromyelitis optica spectrum disorders using contrast-enhanced magnetic resonance imaging , quantitative susceptibility mapping, diffusion tension imaging, and arterial spin labeling with post labeling delay of 2.0 seconds. Transfer constant volume , magnetic susceptibility, cerebral blood flow and fractional anisotropy(FA) value were measured in lesion and normal appearing white matter.
The study will evaluate connectivity regardless whether patients present a clinical type that requires medical treatment. In this point, investigators will include patients with progressive evolution as well as initial forms of the disease (CIS) and properly established forms of multiple sclerosis (MS) in remittent-recidivant (RR) forms. The researches will not focus on medical treatment as some of these clinical forms have no indication for disease modifying drugs.
Background: Multiple sclerosis (MS) affects the brain, spinal cord, and optic nerves. MS lesions can appear on the MRI (magnetic resonance imaging) scans in many ways. Sometimes they light up from the outer edge and fill inward. This is called ring enhancement. Researchers think this type of lesion may not heal as well as others. Corticosteroids are the standard treatment to reduce symptoms of MS relapse. But there is no standard treatment for people with enhancing MS lesions without signs of MS relapse. Researchers want to see if a short-term high-dose course of corticosteroids helps heal those lesions. Objective: To study the effects of short-term high-dose corticosteroids on ring-enhancing MS. Eligibility: Adults ages 25 and older who: - Have MS and a rim-enhancing lesion on a prior brain MRI - Are enrolled in another NINDS protocol Design: Participants will be screened under another protocol Participants will be randomly assigned to get either no treatment or 3 days of treatment with a corticosteroid. Participants will have: - 1 baseline visit - 3 days of high-dose steroids, intravenous or oral. If IV, participants will receive methylprednisolone by IV each day. Participants will also be prescribed medicine to protect their stomach. - Follow-up visits will be at week 13 and week 25 after randomization to treatment or no treatment. Visits include medical history and physical exam. Participants will have blood and urine tests. Participants will also have neurological exams and MRIs. Participants lie on a table that slides into a cylinder. They are in the scanner 1.5-2 hours. They get a dye through a catheter: A needle guides a thin plastic tube into an arm vein.
Explore the benefit of the game-based virtual reality system in improving lower extremity kinematics and balance in patients suffering from disease/disorders including Diabetes, Cancer, Multiple Sclerosis, Arthritis, Parkinson's disease, Cognitive Disorders, Brain Injury, Stroke or Frailty. A four to six weeks of training with 2 training session/week will be provided.
Progressive multifocal leukoencephalopathy (PML) is the most feared complication when natalizumab (NTZ) is used in the treatment of relapsing multiple sclerosis (MS). The risk of PML increases after 18 months of treatment. When switching from NTZ to another disease modifying treatment (DMT) in these MS patients with an active disease, there is a high risk of inflammatory reactivation. Nonetheless, a washout period of several weeks is necessary before initiating a new DMT. The primary purpose of this protocol is to investigate the impact of high dose of oral methylprednisolone, given once a month during the washout period between NTZ and Fingolimod (FTY).
The study will based on qualitative methods investigate motivational factors among patients diagnosed with multiple sclerosis for registering nutrition, environmental factors, stress provoking factors and physical activity (NESPA). The aim is to gain knowledge on motivational factors for using a digital tool for collecting data on NESPA and incorporate this knowledge into a form which can be used in requirement specifications for such a digital tool.
There have been no published studies to date on the effects of backwards walking in persons with MS. Thus it is important that the investigators explore different methods for treatment to help improve balance and gait and prevent injury in persons with MS with gait disturbances and balance impairments.The overall goal of this research is to collect pilot data on the effectiveness of backwards walking as a therapy for improving spatiotemporal, clinical gait and balance assessments in persons with Multiple Sclerosis compared to forward walking.
Objectives: Dimethyl fumarate (DMF) therapy may cause a measureable change in bacterial species of the gut. The primary objectives of this study are: 1. Determine whether a measureable change in bacterial species representation follows the institution of DMF. 2. Determine whether a specific pattern of change in the microbiota phylotype with DMF therapy correlates to onset and severity of gastrointestinal disturbances (heartburn, nausea, flatulence, and diarrhea). 3. Determine whether any instability of microbiota phylotype representation persists following the institution of DMF or whether stabilization relates to resolution of gastrointestinal disturbances. 4. Determine whether there is a correlation between a pre-existing functional bowel disorder and development or severity of gastrointestinal disturbances and of peripheral eosinophilia. Design: Double-blinded, prospective, single-center pilot study. Patient Population: Individuals 18 years or older, with a confirmed diagnosis of a relapsing form of multiple sclerosis. Treatment Groups: This study will be an open-label prospective study design with respect to MS immunomodulatory therapy choice. Study group will be defined as subjects with a relapsing form of multiple sclerosis, as defined by the McDonald criteria, choosing to begin DMF therapy.
This 12 week randomized placebo-controlled study will compare the effects of 10 mg and 20 mg of a mixed amphetamine salt, extended release medication (trade name Adderall XR) to placebo on objective measures of processing speed and memory, as well as on self-reported measures of cognition and quality of life. To be enrolled in the study, MS subjects must demonstrate impaired processing speed on the Symbol Digit Modalities Test (SDMT).
Background: Multiple sclerosis (MS) is a disease that damages the central nervous system (brain and spinal cord). This leads to increased physical disability over time. The disease is lifelong once it begins. Researchers want to learn more about MS s stages and follow them until a person s death. Objective: To understand how the physical and clinical signs of MS relate to its changes over time. Eligibility: Adults age 18 or older with MS or a disease of the brain and spinal cord that may act like MS. Design: Participants will have a medical history and a complete neurological exam. They may have timed tests of neurological function, such as a 25-foot walk and a 9-hole peg test. Participants will have multi-day visits about once a year. Participants will have blood drawn. Participants may have a brain magnetic resonance imaging (MRI) scan. They may also have an MRI of the spinal cord. They may get a contrast agent (dye) injected into a tube in an arm vein. During the MRI, participants will lie on a table that slides in and out of a metal cylinder. Participants will have the thickness of their retina measured using optical coherence tomography. A camera on top of a table uses lasers. Participants will look through a lens and follow instructions. Eye drops may be used to dilate the pupils. Participants will chew on a piece of sterile cotton for 1 minute to collect saliva. Participants agree to have an autopsy at the time of their death and to donate some of their organs to research, such as the brain and spinal cord.
