Welcome. I'm glad you found us.
I'm sorry for all the questions, but your answers will help us help you.
What kind of professionals have evaluated your son? What professionals gave what dxes?
Has he ever had neuropsychological testing?
Has he ever tried medications? If so, what and what was his reaction?
Was it a public school that expelled him? Does he have an IEP?
Any speech or developmental delays?
Any sensory issues (for example, sensitivity to clothing tags, loud noises, food textures)?
What kind of strange things does he do?
Any mental health issues or substance abuse in the family tree?
I recommend getting your hands on a copy of The Explosive Child by Ross Greene. It has helped many of us on this board parent our extra-challenging children.
