I agree about ADD/ADHD becoming one of the overdiagnosed spectrum disorders. I was diagnosed once by a psychologist as has having a "mild" version of it. If true I do not see it impacting my sessions. Indeed I tend to be a relatively quiet sub.

There is a domme I have been doing sessions with the last few years and we have gotten to know each pretty well. She claims that she suffers from ADD/ADHD and that it causes her problems with her vanilla job but not with her domme work.
