If you are lost, forget being found with this bible. Don't be worried, you won't have to change anything you are doing... it's the same old 19th Century stuff, trimmed up to tweak the descriptive language, with no improvements there for patient care, and no new science. Boring.
When I began training in psychiatry, almost 40 years ago, much of the diagnostic psychiatric world evolved from affect thinking: depression and anxiety, euphoria, and misperceptions of reality. That world is rapidly changing.
