I started to say that, but others had said it was for migraines, so I didn't. I'm going to guess maybe Daniel had seizures, too - and the anti-seizure medication might have been what Wecht was holding back, thinking it was best to keep it private - esp if he knew or suspected that ANS also had them.
It's hard to get insurance on celebs or for making movies or commercials or location shoots if someone is known to have seizures.
Having epilepsy is nothing to be ashamed of. Years ago there was a stigma attached to it but I don't believe a doctor would consider it something to hide nowadays.
