My niece has epilepsy due to brain damage from an unrelated illness when she was an infant. Her meds completely control it, and unless someone told you, you'd never know it. Epilepsy is a common effect from traumatic brain injuries and illnesses. I hope the hospital has someone on staff who can help your wife with the right meds and getting them adjusted for her. It can take a little time to fine tune them so they work right with her system,, so make sure that she knows that it's not that they don't work right, it's just an adjustment issue.
