I don't think so. But part of the criteria for ADHD is some sort of functional impairment, so if the person has no impairment in any part of their life--job, school, relationships--then they wouldn't be considered to have a disorder. For me, I have had quite a bit of success, but as I have aged, my ability to cope with the ADHD has been overcome by increasing cognitive demands and a less capable, older brain. So my ADHD is manifesting quite a bit more in my older years. From talking to my doctor, this is not uncommon. Lots of us learn to cope well and then when the load gets to be too much, everything tips, and voila, adult ADHD!

I suggest going to someone who is more experienced at diagnosing and treating ADHD. Your pdoc sounds inexperienced with this disorder in adults.
