If your son says "he can't help it", there is a strong possibility that something neurological is going on, especially if these are unusual behaviors for him. Please refer him to a pediatric neurologist ASAP, to see if there is something significant going on. He may also want to do some psychoneurological tests, to determine if his learning is affected. Sometimes if a particular part of the brain is not functioning normally, those tests can pinpoint where the neurologist needs to look further. I wish you and your son luck.
