I have a friend that had a stroke and after his recovery the mri scan showed major changes in his brain, he was later diagnosed with multiple sclerosis. Is that somehow a consequence due to the stroke. He has also has Demyelination patterns II. Can that be lethal ? How bad can it get ?Is he gonna forget me ? or something.. Cos hes alreeady starting to forget small things, like hes restarting on 4-6 hours
