I know you're reaching out for help but no one can diagnose on a forum the results of your seven year olds test, you will soon get the proper diagnosis and will then know what you are dealing with.  Lots of us have waited for results and trust me it's the worst period when you are left waiting.  It must be even worse when it's your child.  So wait for his test results and come back on and let us know what has happened.  I'll flag up your post so I can follow you.  Hugs from this end, Carol x
