My son had what I would say is a grand mal seizure today. He hit the floor , I was downstairs and heard a thud sound, ran upstairs and found him on the floor, arms and legs stiff and straight as a board, body shaking, convulsing and foaming at the mouth, eyes looking upward and fixed . Neuro office closed today will call in the morning but really shocked this happened. He used to have complex partial seizures as a toddler, stopped depakote when he was 12, now 16 yrs old
