I read that girls tend to be more accommodating in class/flexible in general - and therefore their ADHD or ADD often goes undiagnosed.
This is how my own ADD went undiagnosed for years... couple that with being bright and/or GT, and everything seemed great on the outside. I was diagnosed in college with it, but it wasn't until I was a mother that it became an issue for me. The one thing that I'm thankful for DS5 (and DD3) is that he is able to concentrate for hours on one single thing. I can play on the computer for hours, but not play the same game over and over again, etc... but DS5 does have other characteristics that are very similar to those with ADHD, but those same characteristics are common in gifted children his age.
Boys tend to be more hyper by nature anyway, but even as someone with ADD, who encourages women to get help if they think they have ADD, I really think that ADD/ADHD (I personally think they are separate) is overly diagnosed these days, especially in young kids. And like you, IronMom, I cannot buy into the ADD/ADHD epidemic, even as someone labeled as such.
