How To Cure Grand Mal Seizure?

My daughter will be 15 years old on the 22nd. On Feb 21, she had a grand mal seizure. She has never had a seizure before that date. However, over the past year and a half, she has had sudden jerking motions in her arms and head. She was on med for Primary inattentive disorder (ADD) and her doctor was aware of these movements but did not testing. Right before she had the seizure the jerking movements with her arms were worse then they have ever been especially in her left are. Could this have been some type of seizure all along. Her neurologist had me take her for an eeg but ordered no lab work or anything else. I have called the neurologist many times because I am concerned about what I need to do for my daughter and she has never returned my calls. Her PA left a message on my phone saying the EEG was normal and I have heard nothing else from them. I am an RN and I know more tests should have been ordered. I plan to take her to a different neurologist. What is your opinion.
