Re: this DR Barkley quote states that Neurological tests have no value in the diagnos

Right now, the value of these tests is to see if there's enough of a consistent, measurable difference in the ADHD brain that they can, eventually, be useful for diagnosis. As Dizfriz says, there's a lot of statistical data that shows significant differences. . .but if you look at the data graphs, you'll still see some outliers that don't fit in the majority (but they still have ADHD!)

If this were some simple problem that had its origins in a single area of the brain, then there'd be no problem using imaging of one kind or another to pin down the problem. Most people with ADHD show a difference in size and function of the frontal lobes, but in some it's only the right or only the left. . .and some have differences in the hippocampus, and some don't. Some have differences in the temporal lobes, some don't. Some show a decrease in bilateral functions in fMRIs, some don't.

The only thing they do share is a collection of symptoms that lead to similar problems in cognition and behaviors that negatively affect their lives. As long as that's the only thing that's certain, that's the only thing we can use for diagnosis.
