PET Imaging of Cyclooxygenase-2 in Multiple Sclerosis
Multiple SclerosisBackground: Multiple sclerosis (MS) is an autoimmune disease that has no cure. MRI is the main tool used in the study and treatment of people with MS. A tracer has been developed for cyclooxygenase-2 (COX-2), an enzyme found in the brain during inflammation. Researchers want to explore the role inflammation plays in MS and see if COX-2 is measurable in the brains of people with the disease. Objective: To see if COX-2 is detectable in the brains of individuals with MS. Eligibility: People ages 18 and older with MS who are otherwise healthy. Design: Participants will be screened with their medical history and a physical exam. They will have an EKG to check the electrical activity of the heart. Participants study involvement requires 2 to 3 visits and will last between 1 week and 4 months. Participants will have 2 PET scans of the brain. These might occur on the same day or on separate days. A small amount of a radioactive chemical will be injected through an intravenous catheter. A needle will be used to guide a thin plastic tube into an arm vein. The needle will be removed. Only the catheter will be left in the vein. The PET scanner is shaped like a doughnut. Participants will lie on a bed that slides in and out of the scanner. They will wear a plastic mask molded to fit the head. The scan will last about 90 minutes. Participants will receive the medication celecoxib orally about 2 hours before the second scan. Participants will have blood tests. Participants must avoid certain medications a month prior to the PET scans. ...

Emotions in Multiple Sclerosis
Multiple SclerosisThrough this study, a group composed of multiple sclerosis patients will be compared to a healthy volunteers group to determine if the positive emotions recognitions is preserved in the first group.

A Closed Loop, Doctor to Patient, Mobile Application for Depression in People With Multiple Sclerosis...
Multiple SclerosisMS1 moreThe researchers want to find out if an electronic application called MS CATCH can enhance patients' and doctors' experiences during and in between clinical visits. MS CATCH is a smartphone-based tool which allows patients to enter their mood related symptoms at regular intervals, which is then available to their Neurologist in their electronic medical record. The neurologist is also able to view additional information from their medical record, and receives alerts for changes reported by the patient that raise concern for the patient's mental health.

Optic Neuritis Differential Diagnosis Study
Optic NeuritisNeuromyelitis Optica1 moreBackground: Optic neuritis is a frequent cause of vision loss encountered by ophthalmologists in the Caribbean. The diagnosis is made on clinical grounds. Optic neuritis can occur either in an isolated manner or, most often, as the first symptom of multiple sclerosis (MS) or neuromyelitisoptica (NMO). These 2 demyelinating disorders differ by many means, including treatment and prognosis. MS can cause severe long-term disability while NMO is a short-term sight- and life-threatening condition causing potential relapses, which may require plasma exchanges. Furthermore, disease-modifying therapies used in NMO are different from those used in MS, which can worsen the natural history of NMO. Early differential diagnosis of these diseases is thus crucial for preventing severe visual loss and disability.

Can Fatigability Neuromuscular Explain Chronic Fatigue in People With Multiple Sclerosis?
SclerosisMultipleChronic fatigue is the most common and debilitating symptom in multiple sclerosis patients. This chronic fatigue affects their quality of life by decreasing their capacity to perform simple tasks of daily life. The aim of the present project is to determine whether deteriorated neuromuscular function (i.e. increased fatigability) is involved in this feeling of chronic fatigue. Because the causes of this feeling are multi-dimensional, a large battery of tests will allow us to better understand the origin of chronic fatigue. A better knowledge of chronic fatigue etiology will allow to optimize rehabilitation treatments to decrease the apparition/persistence of chronic fatigue and in fine improve quality of life.

Computerized Cognitive Training in MS
Multiple SclerosisCognitive DeclineWHO: 40 participants with a confirmed diagnosis of Multiple Sclerosis (MS) able to engage in moderate physical activity. WHY: The purpose of this study is to evaluate two computerized brain training tools, which include light physical activity, to see if they can help improve cognitive functions, such as memory and attention, for patients with MS. WHAT: Complete a set of tests (physical and cognitive) at baseline, wear a Fitbit Flex device at home for the duration of the study, 3 supervised sessions for 4 weeks at UCSF, one visit for physical and cognitive tests at one week after the final supervised session, and one final visit 6 months after the final supervised session. WHERE: 20 participants at the UCSF Weill Institute for Neurosciences (675 Nelson Rising Lane, San Francisco, CA); 20 participants at Lausanne University Hospital (Rue du Bugnon 46, 1005 Lausanne, Switzerland)

TRAIN-BW: Backward Walking Training in Multiple Sclerosis
Multiple SclerosisGait Disorders2 moreIndividuals with multiple sclerosis (MS) experience in impairments in mobility and cognition that increase the risk for accidental falls. More than 50% of individuals with MS experience injurious falls within a 6-month period. Current interventions to improve fall risk have focused on forward walking (FW) and balance training, resulting in small declines in the relative risk for falls with a large degree of variability. Interestingly, motor differences between MS and healthy controls are more pronounced in backward walking (BW), yet no studies have investigated BW training as an intervention to reduce fall risk in persons with MS. This study will investigate the feasibility, acceptability and impact of BW training compared to forward walking training on motor function and fall risk in persons with MS.

Immune Profiles in Multiple Sclerosis (MS) Patients and Healthy Volunteers Through Thoracic Duct...
Multiple SclerosisHealthyIn this study, lymph fluid will be collected by cannulation of the thoracic duct, a minimally invasive procedure performed by interventional radiologists. Single time point and serial collection through an indwelling cannula will allow for comparisons between immune cells in the periphery and deep lymphatic system in MS and healthy controls and in MS, changes in responses to a FDA approved therapy ofatumumab.

Gait Analysis in Multiple Sclerosis Patients
Multiple Sclerosis3D Gait Analysis1 moreIn the literature, the results of vestibular rehabilitation treatment applied in patients with Multiple Sclerosis (MS) have been investigated in detail under the headings such as fatigue, physical activity level, and quality of life, and its effects on walking have also been tried to be examined. However, in the studies conducted, gait assessments were made through questionnaires and timed tests, and devices that provide more objective data such as 3-dimensional gait analysis were not used. Again, the effects of vestibular rehabilitation programs on dual-task were not examined in previous studies. Therefore, the aims of our study are: To determine the effect of individually designed vestibular rehabilitation exercises on the kinetic and kinematic components of walking; To determine the effect of vestibular rehabilitation exercises specially designed for the person on gait parameters during cognitive and motor tasks.
