New MS Symptom Prevention Research Initiative Launched in Quebec

Symptom prevention in multiple sclerosis is the focus of a new research initiative launched on Friday by the Montreal Neurological Institute-Hospital, known as the Neuro, in collaboration with the Quebec division of MS Canada, Noovo Info reported.

Key Clinical Takeaways:

• The Racine SP initiative will track 1,000 Quebec residents who have a first-degree relative diagnosed with multiple sclerosis.
• Researchers aim to deploy existing treatments before symptoms appear, noting that early intervention can prevent symptom emergence in 70% to 80% of incidental cases.
• The project will examine genetic, biological, and environmental factors over at least five years, including blood proteins and the Epstein-Barr virus.

The Racine SP initiative will follow 1,000 individuals across Quebec who have an immediate family member with the condition. Close relatives of a diagnosed individual face an approximate 5% risk of developing the disease, though susceptibility varies.

The project intends to move beyond diagnosis to stop the disease before it manifests.

Multiple sclerosis begins years or a decade before initial clinical signs emerge, setting it apart from neurodegenerative conditions like Alzheimer’s or Parkinson’s where clinicians can only hope to slow progression.

Researchers will study genetic, biological, and environmental factors over a minimum of five years, specifically analyzing blood proteins and Epstein-Barr virus infection. This work is led alongside Dr. Simon Thebault, a neurologist at the Neuro and assistant professor at McGill University whose research focuses on the role of the virus in multiple sclerosis.

“We know that today, when we are able to catch the disease early enough, before too much damage settles in at the level of the brain and then at the level of the spinal cord, we are able to stop the disease and prevent new attacks on the nervous system,” Dr. Harroud told Noovo Info.

Early detection typically happens by chance during magnetic resonance imaging scans performed for unrelated reasons. Even with incidental detection, existing treatments prevent multiple sclerosis symptoms from emerging in 70% to 80% of cases.

“And in this context, if we identify signs of the disease, we can for the first time treat them before the appearance of symptoms, but in a voluntary way, not just by chance, not just because someone had a migraine and they had the chance to have an MRI at that time,” Dr. Harroud told Noovo Info.

The research team plans to recruit participants outside major centers like Montreal and Quebec City. Anyone interested in participating can visit the MS Canada Racine SP portal for more information.
