Chapter 22: Psychiatry Overview

Introduction

This chapter of the Language of Medicine text covers the topic of psychiatry, providing an outline of psychiatric disorders and defining major psychiatric terms. More extensive information can be found in the Diagnostic and Statistical Manual of Mental Disorders published by the American Psychiatric Association. The aim is to familiarize students with various psychiatric conditions encountered in clinical practice from a Western perspective, including understanding diagnoses, symptoms, medications, and treatment plans.

Definition of Psychiatry

Psychiatry is defined as a branch of medicine that deals with the diagnosis, treatment, and prevention of mental illness. It is recognized as a clinical specialty, intertwining medical and psychological disciplines.

Specialist Training in Psychiatry

They pursue additional training in psychotherapy and psychopharmacology for typically four years, followed by possible fellowship training in specialized branches of psychiatry.

  • Psychoanalysts: After completing medical training, psychoanalysts undertake an additional three to five years in psychoanalysis, which involves patients relating their thoughts and associations freely to a neutral analyst.

  • Psychologists: Non-medical professionals who complete PhD or EdD programs in psychology without medical training. They specialize in psychological assessment, testing, psychotherapy, and research. Psychologists unable to prescribe medication or perform psychopharmacology training.

  • Other Nonphysician Practitioners:

    • Licensed Clinical Social Workers (LCSWs)
