I read that article and honestly it sounded like media person playing devil's advocate to pull a story out of their rear end to fill a paper for the week.
I will agree that this isn't an outright 'cure', and it could come with complications and such that we don't truly know the scope of at this time, but what's important to PwMS is hope and new theories, instead of reading the same regurgitated stories we've seen over and over again.
I'm biased in my opinion largely because I'm a PwMS who can see the relationship between blood flow and the body's reaction as such makes entirely too much sense.
