They're completely in a state of suspended animation.

This is the deadliest and most disabling form of stroke that we face.

If you see a picture of the brain with a hemorrhage in it, that is all you need to see.

It sounds like this was a massive bleed, it sounds like he progressed rapidly to coma within the first couple of hours and I think the move to operate indicates that they were doing everything that they felt they could. It also indicates a certain measure of desperation.

They probably are treating him with some fairly effective treatments that we have to dehydrate the brain and reduce the swelling and reduce pressure. But it is all mopping up a huge mess after the fact.

When you're on a blood thinner, it's a dreadful problem. You continue to bleed much more, and over a longer period of time.
