Living with Seizures

My son is 6 years old and his seizures happpen on his right side regarding a twitch of the right side and drooling from his mouth. He had this since 2005. He has partial seizures, it is not generalized. It is his speech and behavior area that the seizures effect. He was talking for 6 months from his seizure last year. He woke up and could not talk in April of 2007 and he has the seizures only at night. He has seizures between the hours of 7 p.m. and 10 a.m. He has them all times of night, like 2 a.m, 5 a.m., etc.

I need help trying to figure this out. This has been since 2005. His EEG was abnormal, his MRI CAT scans and all blood work were normal. He is on Trileptal medicine. 8cc a.m. and at p.m. He has a twitch of the right arm and a twitch of the right side of his face and arm only. The last seizure was July 25 at 5 a.m. was a seizure of his eyes rolled in back of his head. we had to rush him to the hospital. He is ok now. i just need answers.
