Hello! My daughter is 13 yrs old and had 8 epileptic seizures from 4 yrs old. There is no etiology for these seizures. She's on Depakine caps(200mg) at the moment and although she hasn't had a seizure since she's on medication, she has minor episodes of excessive salivation, dizziness and oral disorders leaving her with a horrible headache. Please tell me what could cause these "minor" symptoms?
