Pretty common. Possibly the most common combination. Dr. Attwood wrote that it's only a small % that show signs of AS, ADHD, OCD, and Tourettes. But even then the list of other symptoms people Could have in addition to ASD is pretty long. Bipolar, anxiety, ptsd etc etc.
I doubt there's That many people out there that Only have signs of ASD and not of anything else. Possible, but it just seems to me that Most have something else or another or two going on as well. My best guess is that so many of these afflictions are rooted in the same health issues that exacerbate them so they all flare up. Further, as decades have passed doctors & researchers have decided to split out a whole bunch of subtypes of mental health illnesses and give them all different names and diagnostic criteria.. so, that's another reason they're seeing a lot more different illnesses in people instead of just a blanket diagnosis of "mentally ill," or "insane," or "ret*d." etc. Some of it makes a lot of sense, especially if they have clearly different symptoms, causes, treatments etc... but sometimes I wonder why they bother splitting hairs.
