As my DD is in Keppra, and has previously been on other seizure meds, the Keppra, by far has had the least amount of side-effects
. You could ask if some of her mood changes, memory loss, etc. are from the stroke
vs. the Keppra. Please do not wean her off the medication without a Dr's directive... that could cause withdrawal seizures.
My thoughts are with you that your mother gets well soon.
