This doctor posits that the death of oligodendrocytes causes the immune system to send in white blood cells to clean up the mess - the immune system isn't the cause, it's a natural process of the body.
He thinks that the oligodendrocytes die because of hypoperfusion - not enough oxygen/blood to the tissue.

I agree about the immune system and the oligodendrocytes - I've never been happy with the current explanation. I'm not so sure about the hypoperfusion!
