I talked to some people with MS and most of them told me the same story: the trigger event, followed by some time, then onset of a full-blown MS.
I wonder: are those diseases really different? Or maybe this is the very same disease but with a bit different outcomes: myalgic encephalopathy vs sclerous plaques. Both are driven by the inflammation, both have the same initiating sequence.
What leads me to strongly suspect that it may be just different manifestations of the same disease is the involvement of mitochondria in both MS and CFS/ME.
