I'm diagnosed as ASD, and a psych has said I'm almost certainly ADHD but untestable. I have an unusually acute visual memory - I can accurately describe the room I was in while Churchill's funeral was on TV, when I was less than 3 years old. Most university exams were effectively open book because I could recall the pages I'd read as images.
I'm not convinced all the stereotypes about ASD/ADHD superpowers are true myself. And yes, autism super skills don't equate to commercial success for most of us.
