Which psychiatric conditions and treatments are NOT within your expertise?

In another article on this website, I argued that most of us can benefit from identifying one or two areas in our specialty in which we gradually become experts while maintaining our general skills as well. For more on this, please see the following article on this website:

On this page, I want to make a related but different point. Knowledge, treatment options, and technology in psychiatry have grown tremendously in the last few decades. No single clinician can do even a half-decent job of providing competent evaluations for ALL clinical conditions and/or providing all types of treatments.
