Brain damage tied to thinking differs by sex in MS
Key Takeaway
Men and women with MS had similar rates of thinking problems, but brain damage linked to test scores differed by sex.
What They Found
About 38% of women and 42% of men with MS had thinking problems, a difference the researchers did not consider meaningful. Men did worse on verbal memory tests, while women did worse on tests of finding words. In both groups, more damage to brain pathways was linked to worse thinking test scores. This link was stronger in women on tests of overall thinking ability. Loss of brain tissue linked to worse scores appeared mainly in different areas for men and women.
Who Should Care and Why
The study included people with MS and healthy volunteers. People with MS had either relapsing-remitting MS or progressive MS. Researchers compared brain scans from both groups. Only the people with MS took the thinking tests described in the abstract. The findings describe how brain scan changes relate to thinking test scores in men and women with MS.
Important Considerations
You should know this was a study of brain scans and test scores, not a treatment trial. It included 287 people with MS and 172 healthy volunteers. These links do not show that the brain changes caused the thinking problems.

Read MoreUnderstanding MS Research
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 Molecular psychiatry 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.
