My grandson has been screaming people ( classmates, teacher, parents) when he doesn t get his way. He has bothered id neighbors at school by touching them, whispering things he shouldn t and yelling at them. His teacher has had to remove him from the group and even the classroom. We have an appointment with his pediatrician soon and I want to make sure we give as much information as we can to the doctor. Could you give an idea of what types of conditions we are possibly looking at?
