With my history of concussions, the WWE wants to protect me, so I've had to take a lot of neurological testing.
My girlfriend says I have frontal-lobe epilepsy. I have visions. They have slowed down as I've gotten older, but I still have them.
For somebody who has injured their brain, every single thing they say and think will be the subject of their own questioning.
I think I have advanced ADD.
You certainly can't tell anything from the microscopic structure of the brain whether the person was an idiot or a genius.
Traditionally, the treatment for a concussion has been to stare at a wall and wait for your brain to heal itself. Don't watch TV, don't read a book, don't look at your phone, and definitely don't train. It's a torturous protocol for an athlete.
My first memory - at about four - was of numbers. The doctors who study me think a combination of mild autism and seizures I had when I was three have made me experience numbers the way I do.
Neurologists have a host of clinical tests that let them observe what a brain-damaged patient can and cannot do.
I never did think I had brain damage.
