List of psychological conditions, disorders and illnesses
The DSM-5 is the current version of the diagnostic manual of the APA.
It's hard to say there is any such thing as a &quot;strict neuro-psychiatric&quot; definition; these definitions are by their nature not strict at all, but the DSM is probably the closest thing to some level of unified understanding in the field. That doesn't mean everyone agrees with it - they certainly don't - and you can infer from changes from edition to edition that it is all far from settled.
