What are the negative social implications for an adult being diagnosed with ADHD?

Why would you have any negative social implications as an adult? You certainly have control over who finds out that someone has put a label on you. If you get on meds that are right for your condition, it will only help any social dilemmas. I was diagnosed and treated as a child and after neglecting it for 25 years, I was again diagnosed, Adult ADD. My social interaction with people and co-workers has been much, much better.
