What I have read on the subject he had blood clots in his brains, then they discovered his illness in the vessels. Blood clots can come from certain PED's we know.
He didn't have blood clots in his brains. I have read this as well but it is incorrect. The thing is that the capillaries clot together, which might have been translated wrongly. His seizure was because of a hemorrhage which was the consequence of this thing experts call a "cerebral cavernoma" (I am no expert mind)

And, why does someone be titled as a hater when they have serious questions about certain riders? Don't be a baby.
I don't title someone a hater when they question Alberto. If so I'd have to call the entire forum Alberto haters which is certainly not true. Some posters show tremendous hatred towards him like for example Foxxy. So Foxxy I call a hater.
