To make an example of this... "the patient is responding well to medication/treatment for $problem, therefore $problem is the cause and/or part of a criteria that could finalize a diagnosis for $problem" I think I see what you're saying. If $problem is kidney failure, not many people would blink an eye at this method. But something about $problem being purely "mental" has a stigma. A really nasty stigma. Yet this method can still be useful to get people help - that wasn't my personal experience, but I've seen it happen for others. Then again, when I delve into thinking about that, I can't help but shake the thoughts about placebo effect and what exactly defines quality of life in relation to symptoms. I digress. Anyone have extra thoughts on new / uncommon / "non traditional" science in the field? e.g. neuroimaging, genetic factors (SNPs)?
