Epilepsy isn't 'madness', although it was thought to be that or demon possession for many, many centuries. I'm epileptic but I'm not crazy. Nor do I claim to know the "Truth" and have others scribble down my musings~. Muhammed's sayings weren't even gathered until generations after his death and then the ones considered 'valid' by the Caliphs were all that were included in the Qur'an.
