Experienced pastors, deacons, elders and even laymen and women did quite well at discerning the difference between demon possession/oppression and mental illness. And, they could generally detect when both were a factor.
If I had my dissertation handy, I’d give you the references. I’ve misplaced it in the chaos somehow.
