Well there is milder and more severe Asperger's. Even if Asperger's is by definition high functioning autism. Those who have less intense trait are of course more at risk of never getting a diagnosis and they might never find out what was going on with them. Also, with an aspie like person related to me, I think there are issues with them not understanding themselves, because they don't have severe symptoms enough to be diagnosed (well functioning at home/work) so they are in this weird limbo not having AS but having very similar issues as I do. At least I can put things in a nice little box with a label on it.
