HK I get what youre saying but i think many people will see no upside to asd or adhd.
It's certainly interesting, and it's very individual.
I can cite one advantage to my kids' version of ADHD (DS is the only one with a formal dx but DD seems to be similarly affected): They're easy as pie to exercise. I know that sounds like a stereotype but whenever I hear people say "I just can't get Johnny up from the couch" I'm mystified by that (what must that be like?).
Meanwhile I have serious reservations about so called "benefits" like the "creativity" and "ability to see detail that others miss" that is thought of as being part of ADHD. My kids are both highly creative and detail oriented, but how do we know it's from the ADHD and that they wouldn't be like that without it?
I watched a video of Russell Barkley (sp?) debunking the idea that ADHD is a "gift" and he became very heated and agitated as he insisted that there are no upsides to this disorder. Mind you, his is only one opinion, and I'm a firm believer in finding silver linings and finding the water that's in the half filled glass etc etc... I think reframing the situation from a positive perspective can help one cope.
Still, ADHD wreaks HAVOC on my kids' in-school hours. It's very debilitating.
Honestly though... I'll take this 1,000+ over a life threatening allergy. That scares me more than I can articulate.
