A four year old child presents to your child neurology clinic with vomiting and syncope. The parents say he loses consciousness and muscle tone during these strange episodic events. They generally happen at night and last more than five minutes; some even last more than 30 minutes. His pediatrician's note says that during a witnessed episode, he had pallor, miosis, incontinence, coughing, hypersalivation, and tachycardia. He had some staring and eye deviation.
