i wonder if that has anything to do with putting someone with paranoid delusions into a loud machine that you explicitly state is going to scan their brain? maybe that's why there's no good imaging studies prior to drug intervention?
further i am having a hard time coming up with medical conditions that have a single test pass/fail like this.
Maybe, but I don't think most psychiatric patients are in a constant psychotic state that they would take such a strong stand on this. Maybe a few Ken Kesey characters depicted in a cartoonish manner.
But as the article mentions it's not a single pass/fail test they seek but any biological marker at all.
