The diagnosis of depression in disorder

Abstract

Objective: My purpose is to critically evaluate psychiatry's current approach to the diagnosis of depression.

Methods: I have closely examined trends in diagnosing depression, especially since DSM-III, and have considered alternative options.

Results/conclusions: Psychiatric taxonomy is currently based on invalid nosological premises that have worked as a strait jacket for conceptual progress and related biological and psychopharmacological research. A fresh approach that replaces nosological analysis with the concepts of functionalisation and verticalisation is essential.
