I stumbled upon this site recently. I wish I foud it sooner. So our son was diagnosed with Emotional Behavior Disorder, ADD and ODD at 4 years old. He currently take Intuniv in the morning and Guanfacine(Tenex) in the afternoon. As we struggle with severe behavior and anxiety problems and the more I read about Autism and/or Aspergers ... exhibit many features of an autism spectrum disorder including inconsistent eye contact, somewhat limited peer relationships, poor conversational reciprocity, limited imaginary play, a narrow focus of interests, behavioral rigidity, and a number of atypical sensory(sounds, smell, chewing/biting on things behaviors. the more I think he may be on that spectrum. Is 4 years old too young to be accurately diagnose these type of problems? Should we have him retested?
