I think it has less to do with the actual name ADHD as it does with the stereotypes that laypeople think of and with the actual diagnostic criteria. Regardless of the name, how it is viewed is much more of an outside perspective rather than a description of what it's actually like. Autism has a similar issue as well.

Plus, at the time I was growing up the DSM-IV said that you can't have both ADHD and Autism which is probably part of why I was diagnosed with neither.
