What are the disadvantages of being diagnosed with ADD as an adult?

The promise of getting a diagnosis of adult attention deficit disorder (ADD) is that suddenly what may have seemed like a personal failing has a name. The pitfall of getting a diagnosis is that while ADD may roll off the tongue these days like a hip new fad, it is classified as a mental disorder. The label illuminates at the very same time that it incapacitates. And the label can easily become a permission slip for problem behavior; for example, for kids to stop working or for husbands to cheat on their wives because "my ADD made me do it."
