Those are some bold claims, can you share any of your sources that led you to those conclusions?
I’ll agree that if someone has suffered a massive stroke and half of their brain has literally died, there may be no way that is going to recover. The article didn’t seem to be making claims about that rather just that there is some evidence that some regeneration is possible, which sounds like evidence worth looking at if it still exists or ever did.
Lying for profit does indeed seem to be a major industry these days, glad I’m not paying or being paid for that.
