Raelynn has epilepsy. Specifically, she has refractory epilepsy, which simply means that they have not been able to control her seizures through all of the things that they’ve tried, and trying more things likely would not be effective.
That being said, Raelynn’s VNS has eliminated a LOT of her seizures. She isn’t have nearly as many tonic-clonic seizures anymore! That has been a HUGE blessing!
