I have run across occasional studies talking about how expensive ADHD is to a society, but I haven't run across anything that gives a detailed before-and-after evaluation of the monetary and social results of diagnosis and treatment. Is there such a study?

I guess what I have in mind would be a study where a number of ADDers were studied and evaluated before their diagnosis, and then followed for a year or two afterwards to show the actual results in their lives of diagnosis and treatment.
