For a lot of folks with epilepsy, this is nothing new. Plenty of medications that treat epilepsy are known to induce changes in mood, mental state, etc. Probably the biggest one is levetiracetam (also known as Keppra). If you read the warning label, it says it can induce "mood changes", which is a euphemistic way of saying "it can turn you into an uncontrollable rage monster". I've been there. Whatever you think you know about getting ticked off, you haven't felt angry until you've felt it on Keppra. There is no gradation of anger-- no "subtly annoyed", no "getting ticked off", no "this is really getting me angry". Just "zero" and "Incredible Hulk on a bad day". The stuff that annoys you may not be anything that annoyed you in the past, but now it's something that makes you want to bash somebody's skull against the pavement until it goes soft. And there is no warning, no ramp-up-- you just suddenly find yourself enraged beyond all human comprehension, and you're doing everything you can just to restrict yourself to yelling incoherently instead of resorting to physical violence. There's even a cute nickname for this whole horror show: "Kepprage". I'm off levetiracetam now (onto lamotrigine, which is also prescribed as an antidepressant). But it scared me pretty badly. I genuinely fear getting angry now-- because I worry that I'm going to wind up back where I was. I was single when I was on Keppra, but I'm in a relationship now-- it scares me to think what I might do if I ever get back to Kepprage levels of anger, because it could easily cost me my partner. So, to your question: was I a different person on Keppra? I mean, I still responded to my name and worked the same job and had the same favorite foods and such. But I was a lot angrier, I was getting angry all the time, and there was no off switch. It's a valid philosophical question as to whether that makes me a "a different person". Looking to your example, consider that feeling that you have on alcohol, and its assorted side effects and behavioral changes. Now imagine that you were stuck in that mode, 24/7. Would you be "a different person"?
