Depression-related genes linked to more MS relapses

Key Takeaway

Adults with a higher inherited risk of depression had more MS relapses, but the study does not show that those genes caused them.

What They Found

Researchers studied whether genes linked to depression were also linked to MS activity. Adults with a higher inherited risk of depression had more relapses. Across the study groups, relapse rates were about 23% higher for each measured increase in that inherited risk. In the US group, higher inherited risk was also linked to a shorter time before a relapse. That group also had a shorter time before confirmed disability worsening.

Who Should Care and Why

The study included adults whose MS began with relapses and who had European genetic ancestry. They received care or took part in a clinical trial in Canada, the US, or Sweden. The findings concern inherited risk of depression, not whether someone currently has depression. Relapse findings drew on results across the study groups. The link with confirmed disability worsening was found in the US group only.

Important Considerations

You should know this was an observational study of 3,420 adults, followed for about 3 to 5 years. It cannot show that depression-linked genes caused relapses or disability worsening. The abstract does not say whether the findings apply to people with other genetic ancestries.

MS Genetics MS Progression

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 Annals of neurology 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.
