Dr. Rob Tarzwell talks about his experiences being a psychiatric doctor in Canadian ER (emergency room) settings, and the challenges of evaluating and diagnosing patients. Topics include: strategies for distinguishing psych disorders from other conditions; the nature of self and consciousness and how that relates to psych issues; and the impact and meaningfulness of the language used to describe mental issues. We discuss some specific examples of people behaving in offensive ways and the factors that can be behind that. And we talk about 'personality disorders' and what those are.
