Had an interesting discussion with a group of retired US military members (consisting generally of officers who would be in a position to make the following observations). More or less, the claim was made from a former medical officer that it is reasonable to conclude that certain trades have a higher proportion of members with the traits of ADD/ADHD or ASD, among others, given that the beneficial advantage of these traits may serve well for the role - for example, a pilot who has an innate sense of where North is due to an enhanced sense of magneto-reception is going to be a far more effective navigator than someone who does not, just as someone whose brain has a quirk which makes the part of the brain which deals with math blend into their visual cortex is going to have a far better sense of aim.
Given, however, that these are US members who have all retired from service more than a decade ago, most of their information borders on useless, save for that which is empirically valid (such as the existence of a human magnetic sense - one of the officers now works as a physics professor, and demonstrates his own as a Day 1 demonstration). It does bring to mind a particular question - given that it is entirely possible for a person to reach adulthood without any form of diagnosis for neurodevelopmental conditions, what is likely to happen to someone who is only diagnosed during their service? I happen to personally know a Padre who was diagnosed with Aspergers less than a year after he retired from service, so I have reason to believe that there are others like themselves.
As for me, I was diagnosed with a learning disability as a child, but had my paperwork vanish over the years - most likely because as I am a twin, the existence of two files bearing the same surname with a minimal numerical difference led to a perfectly reasonable (though irritating) conclusion that one of those files was a duplicate. I'm 34 now, and I learned that I was in my second year of post-secondary education (so 15 years ago) when my mother finally stopped trying to figure out what had happened. Honestly? I like to think that I've done incredibly well for myself - I'm a member of MENSA, I run a business worth more than $700K, and honestly have never needed any medication. Most important thing I ever learned in my education was not just how I learn specifically, but how to enjoy learning. Whatever "disability" I had is either gone or has been turned into just another tool.
My attitude towards it is very simple - either it is going to pose an issue with my application, at which point I will be given an even greater knowledge of myself than I currently possess, or it is going to be a non-issue. Either way, I gain a productive benefit. I think this is the healthiest perspective to take.
