My mum is 90 and in Jan had her first complex partial seizure. She is on Keppra. She goes absent, smacks her lips and constantly wants to pee. Most recent lasted 18 hours. Not unusual. Should I inform her doctor every time she has a seizure? She has just been referred to a neurologist. I can find nothing on the internet that mentions seizures lasting this long. Any advice would be welcome as I am totally in the dark.
