It is probably no coincidence that forums for ADHD, like this one, usually have some parents who come to the site who have a child with autism. Likewise there are many newsgroups and forums for autism where some members have a child diagnosed with ADHD. Why is this so? Because there is a great overlap of symptoms between ADHD and an autism spectrum disorder. In fact I know that for some of you, your child may have been diagnosed with both disorders at one point or another.
