Should ADHD Be Part Of The Autism Spectrum?

Autism is associated with a wide array of co-occurring conditions. In fact, it is widely discussed that Autistic people have "all the things", meaning that we are prone to conditions that are otherwise considered rare or in some cases problematic. When talking about this topic however, one thing comes up more often than anything else. Attention Deficit Hyperactivity Disorder, or as it is better known, ADHD. This comes up so often that some have already assumed that it is a part of the autism spectrum. The truth is a little more complicated. While ADHD is very common for Autistic people (who have labelled the combination as AuDHD) it is still considered a seperate issue from that of autism. But should it be?
