My daughter is nearly six years old. In February of this year she was in preschool and experienced syncope. She was sent to Children's hospital for evalutation. She has had five abnoral EEG's. They say they show slowing in the left occipital region of her brain. They have no idea what is causing her dizziness, fatigue and headaches. They have not prescribed any medications for seizures so I don't believe it is epilepsy. What else could cause these symptoms. She has had a brain MRI, so that ruled out any tumors, cancer or structural problems. Are there other things that can cause abnormal eeg's? Thank you
