Benign is good.
Since the cause of the seizure is not known, they are probably calling it benign until a proper diagnosis is made. But, at this point, all it tells us is that the doctors don't know what caused it.
Don't get me wrong, I hope all is well with Justice Roberts. I know what it is like to live with epilepsy, so my prayer is that this will not be the diagnosis. All I'm trying to point out is that benign idiopathic does not mean much...yet.
