(STATS) - Chris Infantino was learning too much about the brain at far-too-young an age.

He was only 11 when he was diagnosed with ADEM - acute disseminated encephalomyelitis. Following a vaccination, a brief, but widespread attack of inflammation on his brain caused him to slip into a coma for about 10 days.

The brain healed itself before he came out of the coma. He then went through several months of rehabilitation before all returned to normal, including his standout football skills.
