I agree it's most likely an aneursym. However surgery is a bad sign. Ideally, cerebral aneurysms are treated by endovascular coils and no surgery is required. I assume GW has a good neuro-interventionalist and if so they are operating to evacuate a blood clot that is creating too much pressure on his brain.

Although this sounds grim, remember Joe Biden had the same thing many years ago and made a full (ahem) recovery.

Sometimes an invasive surgery is necessitated by the size/ shape of the aneurysm. There are some brain aneurysms that cannot be treated with coils, purely because of their shape.

As I understand it, the invasive surgery would entail a longer recovery period but there is still the possibility of a full recovery.

I guess what I'm saying is that just because they may be doing an invasive surgery, it doesn't necessarily mean it is a more severe level of aneurysm.
