New MRI Finds Energy Problems in MS White Matter

Key Takeaway

A new safe MRI method shows that people with relapsing-remitting MS have weaker energy production in white matter, which links to more disability and more lesions.

What They Found

Researchers used a special MRI technique called Deuterium Metabolic Imaging (DMI) after giving a harmless labeled sugar to people. DMI lets doctors see how the brain turns sugar into energy-related chemicals (like glutamate/glutamine, called Glx) and into lactate. In white matter (the brain wiring), people with relapsing-remitting MS showed lower signs of oxidative metabolism — that means their brain cells were making less energy in the usual oxygen-powered way. The lower oxidative metabolism was tied to higher disability scores, so worse energy production matched more problems in daily function. Also, lower glucose use and oxidative metabolism matched more MRI lesions, suggesting the energy problem is linked to areas of tissue damage.

Who Should Care and Why

People with MS and their caregivers should care because the study points to an energy problem in brain wiring that connects to symptoms and MRI damage — thinking of brain cells like light bulbs, MS may make some bulbs dim because they can’t get enough power. Neurologists and therapists may use this idea to monitor disease or test treatments that try to boost brain energy or protect axons (the wires). Caregivers can understand that some changes in thinking, fatigue, or movement may come from how well brain cells make energy, not just from visible inflammation. Researchers and clinicians might use DMI as a new tool to see these energy changes over time or after treatments, similar to how an electrician might use a meter to check wiring health. This could affect daily care by supporting treatments or lifestyle steps that protect brain energy (for example, managing sleep, nutrition, or exercise) under medical guidance.

Important Considerations

The study was small — only eight people with MS and eight matched healthy people — so results need testing in larger groups before changing care. DMI is a newer technique and not yet widely available, so it’s mainly useful right now for research and not routine clinic checks. The findings show a link (association) between energy signs, lesions, and disability, but they do not prove the energy problem directly causes the symptoms.

Whether you’ve recently been diagnosed with Multiple Sclerosis (MS) or are seeking to broaden your understanding of this complex, neurodegenerative disease, navigating the latest research can feel overwhelming. Studies published in respected medical journals like Journal of cerebral blood flow and metabolism : official journal of the International Society of Cerebral Blood Flow and Metabolism often range from early-stage, exploratory work to advanced clinical trials. These evidence-based findings help shape new disease-modifying therapies, guide symptom management techniques, and deepen our knowledge of MS progression.

However, not all research is created equal. Some clinical research studies may have smaller sample sizes, evolving methodologies, or limitations that warrant careful interpretation. For a more comprehensive, accurate understanding, we recommend reviewing the original source material—accessible via the More Details section above—and consulting with healthcare professionals who specialize in MS care.

By presenting a wide range of MS-focused studies—spanning cutting-edge treatments, emerging therapies, and established best practices—we aim to empower patients, caregivers, and clinicians to stay informed and make well-informed decisions when managing Multiple Sclerosis.
