The study consists of a 2 hour oral glucose tolerance test, patient reported outcomes, a series of cognitive functioning tests, and outpatient physical assessment using a pedometer.', 'detailedDescription': 'Investigators plan to recruit 100 compliant patients with relapsing-remitting MS who are willing to come fasting for an oral glucose tolerance test to determine the relationship between glucose tolerance and cognition in MS patients.\n\nEligible study subjects expressing interest will be given a copy of the consent to review and will have the opportunity to ask questions. If the subject passes screening, they will be invited for their research visit. Signed consent form at the visit will be obtained before any study related procedures take place.\n\nBaseline Measurements: Measurements for all subjects will include age, race/ethnicity, sex, weight, height, waist circumference, blood pressure. Relevant medical history, current medications, and family history diabetes will be reviewed and documented by both subject report and medical records. If the subject is a woman of child-bearing ability, urine pregnancy test will be done in order to exclude pregnant subjects. All subjects will then have an IV placed and have blood drawn to measure their fasting blood glucose level. Fasting blood glucose above 126 ug/dl would be a screen failure for this study.\n\nLabs: The following labs will be drawn for all subjects.\n\n* Blood glucose management (hemoglobin A1C, insulin-like growth factor, insulin) - these tests show how your body manages sugar\n* Lipids \\& Metabolic Markers (fasting lipid profile, leptin, adiponectin) - these measure signal proteins in your blood for metabolism\n* Cytokine profile - to assess impact of blood sugar and inflammatory factors (molecules that may indicate how well your immune system works) on recovery from your MS relapse\n* Sodium level - to assess how your body uses water\n* Vitamin D25 - measures amount of vitamin D in your body\n* Neuro-filament light measurement - marker of neurodegeneration\n\nOral Glucose Tolerance Test: After baseline measurements and labs are obtained, subjects will drink a 75g glucose drink. Labs (blood glucose and insulin levels) will be drawn every 30 minutes for a total of 2 hours.\n\nIn between blood draws, the subjects will undergo functional testing and complete questionnaires. A neurological exam will also be done that includes 8 functional systems: pyramidal, cerebellar, sensory, brainstem, vision, bowel and bladder, mental, and ambulation.\n\nCognitive testing will include the single Digit Modalities Test (SDMT) which is a timed test measuring thinking speed associating numbers and symbols as well as the cogstate which is a computer based assessment that tests cognitive levels.In addition, all subjects will undergo the sloan Low Contrast Vision testing (LCVA) which assesses your ability to see letters at different contrast levels.\n\nSubjects will complete questionnaires that will ask about their fatigue level, daily activities, sleep habits, and how they are feeling physically, emotionally, and mentally.\n\nAt the end of the visit subjects will be discharged to home with an ActiGraph GT3X+ accelerometer, a waist-worn device, to measure community-based ambulation (a measure of physical activity). Subjects will complete 7 days of wear-time and will return accelerometers by mail.\n\nThis study only requires one visit to the University of Virginia and will take approximately 3 hours.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT'], 'maximumAge': '59 Years', 'minimumAge': '18 Years', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'Persons with RRMS or CIS between the ages of 18-59 who are not diabetic or on glucose regulating medications.', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Ability to provide informed consent\n* Diagnosis of Clinically Isolated Syndrome (CIS) or Relapsing Remitting Multiple Sclerosis (RRMS) confirmed by McDonald 2010 criteria\n* EDSS \\< 6.5 at time of visit\n\nExclusion Criteria:\n\n* Diabetes type I or II\n* use of glucose regulating medications\n* fasting blood glucose of \\> 126 mg/dl\n* known cardiac or respiratory disease\n* morbid obesity (BMI \\>40)\n* steroid exposure within 4 weeks of enrollment\n* pregnancy or current use of hormone replacement therapy'}, 'identificationModule': {'nctId': 'NCT04748302', 'briefTitle': 'Impaired Glucose Tolerance and Cognition in MS', 'organization': {'class': 'OTHER', 'fullName': 'University of Virginia'}, 'officialTitle': 'Impaired Glucose Tolerance and Cognition in MS', 'orgStudyIdInfo': {'id': '21791'}}, 'contactsLocationsModule': {'locations': [{'zip': '22903', 'city': 'Charlottesville', 'state': 'Virginia', 'country': 'United States', 'facility': 'University of Virginia', 'geoPoint': {'lat': 38.02931, 'lon': -78.47668}}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'University of Virginia', 'class': 'OTHER'}, 'responsibleParty': {'type': 'PRINCIPAL_INVESTIGATOR', 'investigatorTitle': 'Principal Investigator', 'investigatorFullName': 'J.
