It's not a "gift" or an "advantage", but it's not necessarily a disadvantage either IF the individual learns the proper coping strategies and can structure their work/life in a way that can make the ADHD less of a liability. It takes hard work.

Learning to overcome disadvantages doesn't cease to make them disadvantages.

Ok, well how about this: I don't ever remember what happens in meetings. Because of this, I learned to take really good notes. As a result of my coping strategy, I always have a distinct advantage over people who don't have ADHD. I can look at my notes from 6 months ago and tell you what we talked about in a meeting.

I don't really think of it as a "disadvantage" because it's really just about knowing your personal limitations. One of mine is that I can't remember shit. Some people struggle with complex math problems (which I would say is a bigger weakness than memory issues which are easily solved with an iPhone and a notebook.) It doesn't have to be a weakness if you manage it.

Not being able to keep a complex math problem in ones head would be a memory problem as well, would it not... before my age 34 diagnosis - forget math all together... my working memory was abysmal; now I am completing 2nd year IT: ComSci. I have a chance, thanks to that "demon" stimulant medication, and a environment, where I am not told I am "lazy" any more. This article, while seemingly accurate, leaves out the obvious rare case of actual ADHD.
