I believe seizures can be the result of illnesses other than epilepsy. MS is one I believe and brain tumors is another. There are probably others. I'm not saying Burkett doesn't have epilepsy, he might. We just don't know from that statement.
It does not matter what causes the seizure... 2 seizures and you now have epilepsy... thats the deal... case closed...
n. pl. ep·i·lep·sies
