Epiletiform discharge

My son is now 7 yr old. I remember clearly january of this yr, 2ndweek, he went home one afternoon saying his head is aching. He has a habit of jerking his head to know if his head is hurting. If he jerks his head and dont feel anything he would say nothing. But when he jerks his head ang felt something he wud say to me that his head is hurting. On the 2nd day he comes home again saying his head is aching. And on the 3rd day when he complains to me his head is aching i noticed something weird. He is starting to blink his eyes constantly. I told him to stop and even told him that i wud spank him if he wouldnt stop for i was scared it wud bcome hs mannerism. But as the day goes by, i noticed that he cannot stop himself from blinking rapidly. I had him checked after i heard him say one time while he is watching tv. "oh there it goes again! I feel so dizzy its like im in the siso" i was so scared when i heard him say that. I first went to the optamologist after being advised that maybe it is bcoz of his eyes having astigmatism. But the optalmologist said my sons eyes are in perfect condition. And he advised me to go see a neurologist.But beacause our place is far i was not able to do that right after. He celebrated his 7th bday last feb 24, one month after that blinking period i noticed that it is gradually fading away and his blingking of eyes are getting normal but to my dismay he is having another as i thought as mannerism. He keeps on jerking his head. The one he used to do before when his checking if his head is aching. And this time he is doing it rapidly. Every after 4 seconds he wud jerk his head and i noticed heis doing it even when he is sleeping. I had him checked already by a neurologist because he is blinking his eyes and jerking his head at the same time. And his eeg say he is having epileptiform discharge during sleep. Im sorry if my letter is long but i am so sad to know this for he is my only child and he is a bright child. Im scared that this would affect his development. He is just 7 yr old but he is now on his 3rd grade this comming school yr. I know that he is advance academically compared to others with his age, but what i noticed is that his motor skills were late. Because he cannot write properly. His writing is ugly and often writing like he has a dislexia. But when he can change the writing once i reminded him. And also his 2nd grade teacher told me that he is not listening in school anymore and is just playing all the time. And he cannot controll his anger. His neurologist gave me dekopene and told me that he wud take this for two years.
