I'm not convinced that the brainscan patterns uniquely identify psychopaths. There are lots of things that frontal lobe dysfunction is also correlated with: ADHD, Bipolar disorder, and psychopathy. I suspect comorbidity (meaning: how likely you are to have the other diseases given you have one) is quite high, but I'm not convinced that frontal lobe dysfunction implies any or all of these disorders.
