This is just my opinion, but I think a lot of misdiagnosing goes on. Autism and ADHD can be comorbid and often are----- but ADHD has become quite the popular diagnosis.
My son has a developmental delay called sensory integration disorder also affecting the nervous system. I've been alerted to the fact that he would have been very easy to misdiagnose. As occupational therapy and lots of sensory activities (which he thinks are a lot of fun and are good for any child) have really worked so awesome for him---- I'm so glad that we got the right diagnosis in the begining.
So I think you also have to listen to your head and heart and believe in what you're being told. Good luck.
