My sister had a grand mal/tonic clonic seizure at work for the first time ever. Was taken to the Emergency Room and was questioned whether or not a true seizure, even after the description her coworkers gave was that of a grand mal. Later that day after being released she again, had a sever grand mal seizure on me in the car. Was admitted overnight and later released. Has since seen a neurologist and basically sent her home on depakote for two years. Ironically, we are being told ALL her tests are negative including for infection. Please help
