Simple partial seizures

Does anyone have simple partial seizures that progress like this: first you feel somewhat anxious, then your heart beats faster, your tongue briefly sticks to the roof of your mouth and then you make a vocalization like an aaahhhh sound? I don't think this is a panic attack. My son has these every two weeks. He has several episodes within the course of the day for two days. Then he goes another couple weeks and it happens again. Any thoughts? Thanks!
