This is true, as a broad statement at least. I can claim no expertise in the area, so I can't comment on the potential to reverse any such changes.

It is also possible that they are not caused by negative life experiences, and are somehow inherent in the organization of a particular person's brain.

Just because something is caused by experience doesn't necessarily mean more experience can completely reverse it.
