I'm currently reading a book by a neuropsychiatrist, called "hippocrates Cried"
"The Decline of American Psychiatry" I find it to be impenetrable, though not because of any medical terms he uses. Maybe you would like it. The author is Michael Alan Taylor. His complaints seem to be all over the place, but he's definitally in favor of investigating the neuro part of neuropsychiatry. I don't think any of the research has come far enough to be actively useful, but the book does help me sleep. As I said, it might make more sense to you.
