The Pathological Basis of MRI Signal Changes in Multiple Sclerosis: A Longitudinal In Vivo-to-Postmortem Study
National Institute of Neurological Disorders and Stroke (NINDS)
Summary
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.
Description
Objective. The goal of this protocol is to understand how the pathology of multiple sclerosis (MS) relates to its evolution over time as observed through neuroradiological, clinical, and biological data collection in vivo. Study population. This study will enroll up to 200 individuals with MS, targeting 100 study completers, across various ages and stages of the disease, as well as up to 50 appropriate disease and non-neurological control participants, for a total of 250 participants. Design. This is a longitudinal cohort study in which participants will be seen approximately annually at…

* INCLUSION CRITERIA: * Diagnosis of MS according to consensus criteria at the time of enrollment OR diagnosis of a disease that shares clinical, imaging, or biological features with MS OR individuals without known CNS disease. * Age greater than or equal to 18. * Able to participate in study procedures and provide high-quality clinical research data (for example, prior MRI scans show ability to tolerate the MRI scan with minimal motion artifact). * Willing to return to NIH for follow-up visits approximately annually (or every 5 years for non-CNS controls) until the time of autopsy.
