There is little surprise that if a brain is behaving differently, that we can see differences in neurotransmitters. Like the Serotonin Hypothesis, that doesn't mean the neurotransmitters themselves are part of the physical cause and not just a consequence.

It's like trying to diagnose and treat a political crisis by observing telephone connections. We see stark changes in telephone use in a crisis. If we meddle with the telephone exchanges we might improve or harm various types of event. It's not really about the telephone calls though, we are just hacking at the messaging of an external event we are ignorant of.

A conspiracy theory induced panic might be superficially "solved" but cutting all the the phone lines. We have not identified or solved the cause though and people don't find life without telephones (dopamine) worth living so they plug them back in (quit their anti-psychotics).

Well, sure. I guess nobody thinks that the dopamine just appears/disappears by itself. Of course there is an underlying structural cause.

But currently we're unable to image live people at that resolution, not even dead people yet.
