He was on on Keppra for 18 months (full dose for 12 months and half does for 6 months) and stopped 6 weeks ago. He has had multipe EEGs, doctors have confirmed nothing suspicious in any of them, and have given no specific diagnosis. His last seizure was in March of 2018, and the seizures then consisted of lost speech, speaking nonsense, eyes rolling back, and shaking. This new episode he had the other day was the only one that consisted of the bright light & sweating. Thank you in advance for your help!
