I have a 23 yr old son born with Oro Facial Digital Syndrome. Just in the past 2 months he has been presenting seizure like activity in the morning while eating. Symptoms include jaw tightening, drooling on one side, unable to swallow at times, jaw quivering,and what appears to me, the vagus nerve swallowing on its own. These spells last from 30 mins to a couple hrs. He is responsive though very sluggish. During the worst episodes, his eyes are rolled up in his head and are bloodshot. He always seems to vomit after the bad spells. Blood work, CT scan and EEG were all negative. A trip to the ER during one episode produced no answers. (CT scan was performed then with bloodwork). He is active, works part time and is able to communicate this "aura" from the onset. I am very confused as to why I see this only during breakfast. He takes Ritalin LA 40 mg once or twice a day and Risperdone 2mg at bedtime. He has been on the Ritalin since he was 4 and the risperdone since 16 yrs old, so the meds arent new. HELP!!!!!!
