WWE: Brock Lesnar has had more concussions than Daniel Bryan

[Pinkfloyd]

More likely that the test found something vulnerable and at risk (Something similar to edge's neck) than actual brain damage. I think the docs bryan kept going to would have certainly found noticeable brain damage especially with the info that he was having seizures (that i can only assume the doctor was aware of)

As far as I can tell, it was something that was tested for that wasn't showing up in CT scans and EKG's which are the norm for this particular situation. DB made it sound like it was lesions that were showing up in this test but not the regular ones he was doing. There is still some forms of brain damage that they can't identify with normal testing.
