... kind they are.When they start he takes a deep breathe and talks in a child like voice and holds on to your hand really tight. Sometimes he will start coughing afterwards and even vomit some.They last anywhere from a minute to 5 minutes. He is 21 years old and has mental issues such as adhd and autism but he has just started these seizures within the last year. They started soon after he broke his leg and hit his head on the side of a car while running in a parking lot playing with his sister. He has had CT scans and MRI's they all are normal. Does anyone here know what these are? Or has anyone else had these? Please Please help us get some answers.Thank you
