I don't know, all of the traits he listed seem much more geared towards ADHD than autism. He made no mention of social struggles beyond those caused by his distracted chronic lateness and unfulfilled promises. No mention of any sensory issues or significant anxiety, nothing about a need for rigid routine and a discomfort with change, or about specific all-encompassing interests. I think the ADHD diagnosis is accurate, without underlying ASD. Autism and ADHD can often be comorbid, but they aren't always, or indeed most of the time. My sister has ADHD with no autism, and I have autism with no ADHD.
