My grandson, 2.5 years old is having cluster seizures, approximately 6-8 a day. They last only 5-8 seconds and then he becomes sleepy. He has had neg MRI, and positive EEG for frontal seizure. Medication is being given but they have not slowed, about the same number. We cannot get an appointment with a specialist until June 3, went to ER and they sent us home stating this was not something they would admit or get in sooner. When are they an emergency so that someone needs to evaluate them....since we are trying to wait as they have ask for the appointment and not rush back to the ER. His pediatrician has not even phoned to check on him since the ER visit.
Possibly your grandson has frontal lobe seizures. I would like to know his antiepileptic Chat Doctor.  also, please mention his body weight. Possibly his antiepileptics needs modification. If he ever continues to have seizure >5 minutes or not get awake from post octal state, or you feel some gurgling sound from his chest after seizure, then It's must take him to emergency. Otherwise, in case of seizure, simply make him lay in lateral position during seizure at home and keep strict adherence to medications.
