Why did doctors assume that MS is autoimmune? Stroke isn't autoimmune....maybe "autoimmune" just means we have no idea why.
A clarifiacation - when you say immune system is activated, I would assume BBB is compromised (probably a natural response) in the above cases too.
This also brings up another point made by a neuro (was it in NYT?) that MS culprit is some gene (that regulates immune system, I must add). That would still not explain BBB compromise.
