Filter by:Background: - Magnetic resonance imaging (MRI) has been used for decades to help diagnose and monitor neurological disorders like multiple sclerosis (MS). Researchers want to improve how MRI pictures are taken. They also want to learn more about using newer MRIs with stronger magnets to get better pictures than standard MRIs provide. Objectives: - To collect data that will help researchers better understand MS and related diseases. Eligibility: - Adults 18 and older with MS or MRI findings that appear similar to MS, or with other neurological diseases that may look or act like MS. - Healthy adult volunteers. Design: - Participants will be screened with a review of their medical records. - Participants will have a baseline visit. It will include a physical exam, medical history, and neurological exam. They may have blood tests. - The study will last indefinitely. - Participants may have MRIs. Some MRIs may include a contrast dye. For this, a needle will be used to guide a thin plastic tube into an arm vein. - Participants may have up to 2 lumbar punctures per year. Skin will be numbed and a needle inserted between back bones will remove fluid. - Participants may give saliva samples and have an eye exam. - Participants may have evoked potential tests. These measure how the nervous system responds to different types of stimulation. Participants may sit in front of a TV and watch pictures on the screen. Or they may wear earphones that make a clicking noise or static. Or they may get a small electrical shock that may tingle and cause a hand or foot twitch. - Participants may have tests of strength, spasticity, sensations, balance, and/or walking.
Background: - Information and samples collected from participants in medical research studies can be useful even after the original study is complete. Researchers can use the information and samples to learn more about multiple sclerosis or other immune system disorders. They can also be used for research into other disorders. Researchers would like to get permission to use samples collected from older studies to launch new lines of research. Objectives: - To look at information and samples from earlier National Institutes of Health Neuroimmunology Branch studies. Eligibility: - People who provided samples and medical information for earlier studies. Design: - Researchers will contact people who took part in earlier studies. Researchers will ask if they can study previously collected data and samples. - Data and samples may include physical exam data and psychological test results. Imaging study results are included. Preserved samples of body fluids and tissues may be studied. These include blood and urine samples. - No new treatment will be provided as part of this research study.
