Quick back story: Back in February I had a dissection in my vertebral artery which lead to a cerebellar stroke. The doctors didn’t realize it was a stroke until 2 or 3 days later, so I didn’t really have much intervention and they said that basically the left half of my cerebellum is dead.
A question I asked the doctors and never got a clear response is, what happens to all the dead brain tissue? Does it just shrivel up and hang out for the rest of my life? Does it get broken down and I have a void in my skull? The still-living parts of my brain want to know!
I’ve tried googling, but my google-fu is weak on this one. All I get are sites talking about how the brain can regenerate somewhat after a stroke (which I don’t understand, I thought once a brain cell was dead, it was dead).
