No, it's trying to see if they have a condition which is readily and effectively treated through medication. I have ADHD, and my daughter has ADHD, so I've been through this a few times with the docs. The _gold standard_ for determining if a patient has ADHD is treatment with stimulants. There are assessment surveys they have you fill out and such, but there's tons of other underlying issues which can cause similar symptoms and lead to false positives. The best, easiest, most reliable way to tell if someone really has ADHD is to give them Adderall and see what happens.

My psychiatrist says that he has done this even with patients who end up getting diagnosed with other issues like bipolar. Why? Because despite being a scheduled drug, stimulants are incredibly safe at pharmaceutical doses, without any serious side effects. It's harmless to try, and if it doesn't work you move on to try something else.

Btw what studies have been done have shown that if anything ADHD is under diagnosed, and severely so in the case of girls. A lot of people who have had other underlying issues have initially been misdiagnosed as ADHD, but this is not the same thing as general over diagnosing, and generally is because ADHD must be first considered and ruled out before moving on to conditions which require the use of more serious drugs.
