Why does multiple sclerosis (MS) progress quickly in some people while others stay stable for years? A landmark study of brain tissue from 287 donors reveals that the answer lies in distinct pathological patterns—and your genetic background may determine which pattern you develop.
The Research
Researchers from the Netherlands Institute for Neuroscience analyzed brain tissue, clinical histories, and genetic data from 287 MS brain donors in the Netherlands Brain Bank. They focused on four key characteristics: inflammation around blood vessels, clusters of immune cells in the brain, the presence of “broad rim” lesions, and the brain’s ability to repair myelin (the protective coating around nerve fibers).
Lead authors Lukas Lutje and Alida Chen found that these four features created distinct disease subtypes. People with broad rim lesions were more likely to have a severe, fast-progressing course. Those with poor myelin repair capacity had more chronic, widespread tissue damage. Importantly, certain genetic variants—previously linked to higher MS risk—were strongly associated with more inflammation and immune cell clustering. A specific variant tied to faster clinical progression was directly linked to the development of broad rim lesions.
“MS is not one single disease process,” says researcher Aletta van den Bosch. “Different inflammatory and repair mechanisms dominate in different people, helping explain why the disease can follow very different paths.”
Why It Matters for Your Brain
This study shifts how we think about MS and brain health in general. It confirms that biological diversity—not just luck—drives disease severity. For anyone curious about their cognitive future, it underscores the importance of understanding your own genetic and inflammatory profile. While MS is unique, the principle applies broadly: your brain’s health is shaped by a mix of genetics, environment, and lifestyle. Personalized approaches are the future of neurology.
What You Can Do
You can’t change your genetics, but you can influence inflammation and repair processes through diet, exercise, sleep, and stress management. Stay informed about advances in biomarker imaging that may one day detect these tissue patterns in living patients. For now, knowing your family history and maintaining a brain-healthy lifestyle are your best steps.
