Generalization from one occurrence is never a good idea.
The Surgeon Genral's 1999 or 2000 report on psychaitric problems
addressed the over/under diagnosis issue, and it cam edown on the side
of underdiagnosis. There is ample evidence that incorrect diagnosis is
occurring, but, when I took a look at the ADHD-diagnosis picture from a
broad point of view over more than a decade, I came to the conclusion
that there is substantial undrdiagnosis, especially of younger ADD
girls. I recall recent studies which back this up.
