Pathological Basis of MRI Signal Changes in Multiple Sclerosis
What this study is about
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.

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.
Primary outcome measures
Correlation among in vivo imaging, postmortem imaging, and pathological characteristics of individual areas of tissue damage ("lesions") in the brain, spinal cord, and retinas.
Time frame: annual visits
Correlation among in vivo imaging, postmortem imaging, and pathological characteristics of individual areas of tissue damage ( lesions ) in the brain, spinal cord, and retinas. Priority will be given to measures of myelination, axonal preservation, inflammation, and astrogliosis, as judged primarily by histological stains and immunohistochemistry.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
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. Note: participants who become too sick to return to NIH will not be removed from the study.
- Willing to undergo autopsy with donation of at least the brain, spinal cord, and retinas.
- Able to provide informed consent at the time of initial study enrollment and willing to appoint a Durable Power of Attorney (DPA) if an advanced directive is not already in place.
- Except for non-CNS controls, simultaneously participating in another screening or natural history protocol within the NINDS Neuroimmunology Clinic at the time of study entry.
- Eligible NIH employees and staff may participate.
Exclusion criteria
- Unwilling to allow sharing and/or use in future studies of coded samples and data that are collected for this study.
Where
- Bethesda, Maryland

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
