relapsing/relapsing & collateral vein formation

I know we think that the cyclical nature of early MS is due to the plasticity of the brain alone - recovering and finding new pathways to work around the lesions -

- but is it possible that an occlusion of the veins causes relapse, and the subsequent formation of collateral veins around the blockage permits a return to a more normal state?

-

Just a thought I woke up with today, no worries if it's rubbish!

I don't think it's a crazy thought at all. Look at the pure logic of it: your body "stays in front of it" until all the collateral pathways, etc., are all used up and there are no other effective routes. Makes sense to me!

i have been thinking that several patients in finnish site said that bowing neck down front may cause very nasty sensation in the whole body, like a flash going through it.
well this would make sense, if bowing your head makes the veins even more narrow..

that sensation is called "l'hermitte's sign", and it is a temporary reaction to the temporary pressure placed on a lesion of the cervical spinal cord, when the head is bowed.
