Hidden behind all of the new drugs and breakthroughs reported at the 2024 ECTRIMS meetings was one paper that caught my attention.
It was that, after several years of study, simvastatin had no benefit for multiple sclerosis.
Statins for MS (and for Alzheimer’s disease) have been bandied about for some time, with arguments based on theoretical ideas, and small studies, that they’d have a beneficial effect on the disease – maybe from anti-inflammatory and other properties. In addition, they offered the benefit of being widely available and comparatively inexpensive.

Because of those studies, 15-20 years ago I used them off label for MS in a handful of patients – sometimes as an adjunct to their current treatment (limited at that point to interferons and Copaxone), or in patients who couldn’t afford the FDA-approved drugs. Although not without their drawbacks, the statins are relatively well understood and tolerated.
At some point, for reasons I’ve long forgotten, they all came off of them (at least for MS purposes). Maybe for side effects, or lack of benefit, or because new medications, with much clearer efficacies, were rolling out.
Now it seems pretty clear that statins don’t work for MS.
So was it a bad idea to try? No. Without asking questions we don’t find answers. If they’d worked out it would have been great, another tool on the neurology workbench to reach for in the right situation. It might also have led us to new avenues in MS treatment.
But it didn’t, and that’s fine. Although they don’t get the attention, we learn as much (sometimes more) from negative studies as we do from positive ones. If we put people on every drug that initially showed promise for their conditions, my patients would have a pretty huge medication list. For Alzheimer’s disease alone I remember studies that once suggested ibuprofen, statins, estrogen, nicotine, and several vitamins might be effective (“might” being the key word). Today we’re looking at the PDE5 inhibitors and semaglutide. The jury is still out on them, but whichever way it goes we’ll still learn something.
The statins are good drugs. Their benefits in cardiac and cerebrovascular disease can’t be disputed (I’m sure someone would, but that’s not the point of this piece). But, like all drugs, they don’t work for everything.
We learn from both and keep moving forward.
