I just read the following study in PLOS one titled: Anatomical Brain Images 
Alone Can Accurately Diagnose Chronic Neuropsychiatric Illnesses.

It can be found here:

http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0050698

The claims of the study seem impressive:

"In MRI datasets from persons with Attention-Deficit/Hyperactivity Disorder, 
Schizophrenia, Tourette Syndrome, Bipolar Disorder, or persons at high or low 
familial risk for Major Depressive Disorder, our method discriminated with high 
specificity and nearly perfect sensitivity the brains of persons who had one 
specific neuropsychiatric disorder from the brains of healthy participants and 
the brains of persons who had a different neuropsychiatric disorder."

The research design seemed to be adequate (at least to me) but I don't have 
enough detailed information about MRI to know whether this is a really 
important breakthrough or just another soon-to-be-forgotten study. The fact 
that it was published in PLOS one rather that Science or Nature makes me 
suspect the latter. Would anyone with more expertise in interpreting MRI data 
like to provide some comments on the study?

Thanks,

-Don.
