I have mini simple partial seizures for few seconds without loss of awareness, I can lesson to someone, s talk but unable to response him, I feel unexplained sensations during the seizure, and focusing on one thing or every thing seems strange to me, and start breathing long. I am on epival cr because I had seizure during sleep, and used keppra and oxcarbazepine for partial seizures but does not work. Please indicate best medicine for my simple partial seizure. Note: I am also taking warfarin because of mechanical valve.
