My son age is 9 months,he was seizure attack once in hyper pneumonia and never observed  seizure after that. He was not in condition to do EEG test and EEG facility was not in city.Docter prescribed  phenobarbital 20 mg 4 ml per day.After six months we have done EEG test in Delhi and report was normal. Docter asked to stopped phenobarbital slowly. In last few days we have observed abnormal behavior like bruxism and clenching face.
