  1. Clinical Trial: Gut bacteria and MS

    The Yale-Griffin Prevention Research Center, the Multiple Sclerosis Treatment Center at Griffin Hospital, and Yale University are teaming up to study whether changing the bacteria in the gut can affect the process that leads to the development of multiple sclerosis (MS). This ...
  2. Clinical Trial: Virtual Reality to Improve Quality of Life

    Participants with MS and other neurological disorders will be recruited to complete sessions of virtual reality (VR) viewing and game playing. VR has been shown to have therapeutic benefit in certain patient populations and requires further clinical study to determine the exte...
  3. Research Study: MS Biomarkers

    The Sutter Health MS genetic study is recruiting people with MS from ten sites across its healthcare system to participate in a DNA sequencing study. The main objectives are to identify biomarkers of disease subtype, progression, and treatment response. The study is open to cu...
  4. Clinical Trial: Pathological Basis of MRI Signal Changes in Multiple Sclerosis

    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 the stages of multiple sclerosis and follow...
  5. Research Study: Seeking first degree relatives of people with MS for study of risk factors

    The goal of this study is to learn more about the causes of and risk factors for MS by studying first-degree relatives of people with MS and comparing them to people who are not first-degree relatives of someone with MS. We will use the data collected to develop a risk algorit...
  6. Clinical Trial: Computerized Cognitive Training

    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 people with MS. Participants would complete a set of tests (physical an...
  7. Clinical Trial: Ocrelizumab in Adults With Primary Progressive Multiple Sclerosis

    This study will evaluate the effectiveness and safety of ocrelizumab ( Ocrevus®) compared with placebo in participants with primary progressive multiple sclerosis (PPMS), including participants later in their disease course. This study focuses on upper limit disability progres...
  8. Research Study: International MS Microbiome Study

    This study aims to understand the role of gut bacteria in MS, and by extension allows us to look at the effects of diet and environment on the gut microbiome and MS disease susceptibility and progression. For this study, we are asking that participants donate blood and stool ...
  9. Research Study: health behavior and wellness outcomes with wheelchair use

    Very little is known about health behaviors and the impact on symptoms in adults with MS who use wheelchairs. The Exercise Neuroscience Research Laboratory at the University of Alabama, Birmingham invites you to participate in a voluntary study of health behaviors in adults wi...
  10. Research Study: Pediatric RRMS

    Researchers are asking teens with MS and their siblings without MS between the ages of 12-18 to participate in an observational study.  With an MRI using a stronger magnet, a specialized picture of the brain, researchers at UTSW might predict an if an individual may have diffi...
