Hi....I had a tonic clonic seizure for the first time at 69yrs old a year and a half ago and another seizure about a year after that because I forgot to take my keppra. Since then a year later no seizures and I have been weaning off the keppra gradually on my own. I am down to 125mg once a day and no effects so far. A lot is unknown about seizures. Some is genetic and some sudden onset like mine. Maybe in a 100 yrs we will know more. God Bless
