speech, auditory processing problems, auditory memory problems, sensory integration
disorder, dyslexia as well as problems with attention and focus. So I know what it is like to have multiple diagnosis that overlap and make it hard to sort out the root cause of difficulties.
From your post it sounds like he is trying to communicate, but can't.
