Do the changes cause symptoms or does the state of mind cause the changes?

It's been shown on brain scans doing meditation changes the brain. That brains of lefties and righties are different. You could say everything is matter of brain changes.

Or you could say the changes notable on brain scans or the chemistry itself doesn't really matter.

And no, despite the fact I have wildly troubled, there is nothing wrong with MY brain. At least I don't like to think of that this way. All I know for sure that if I am in objectivelly better place, I still get ups and down, but I ride them out much better. So it cannot be only about chemicals and changes in the brain. My brain couldn't all of sudden changed with me moving to Prague, could it?

my point was though that some people adopt the broken brain theory to self-defeating matter (and does it really matter if trauma changed your brain or not? How will that help you out... there are means of getting over trauma that don't involved top notch neuroscience. People lived and survived traumas throughout the history. There were no brain scans and fancy meds, or even fancy therapists during thirty year's war... or during other troubled long gone time.... yet many gotten through, lived on, created great things... ). I think the hyper focus on biology only makes it worse. We got so obssesed about scanning brains that we forget our souls. And maybe that is the problem. Maybe that is why the stats say 25% of Americans (not sure about stats for rest of the world) have some mental health issues.
