This document discusses different systems for classifying mental disorders. It describes the International Classification of Diseases (ICD-10) published by the World Health Organization and the Diagnostic and Statistical Manual of Mental Disorders (DSM-V) published by the American Psychiatric Association as the two major classification systems used internationally. It also summarizes an Indian classification system adapted from ICD to better suit local conditions, grouping disorders into categories like psychosis, neurosis, and special disorders.

2. Classification of mental disorders

3. Introduction
 Classification is a process by which complex
phenomena are organized into categories,
classes or ranks so as to bring together
those things that most resemble each other
and to separate those that differ.
 Like any growing branch of medicine,
psychiatry has seen rapid changes in
classification

4. Classification of mental disorders
 Two major classifications in psychiatry:
 1. ICD_10(International statistical
classification of diseases and related Health
Problems-10th Revision,1992)-WHO
classification.
 This is WHO’s classification for all diseases
and related health problems. The chapter ‘F’
classifies psychiatric disorders as mental and
behavioral disorders and codes them on an
alphanumeric system from F00—F99

5. Contd…..
 2. DSM –V-TR (Diagnostic and statistical
Manual of mental disorders Vth edition, Text
revision, 2013) –American Psychiatric
association.

aspects and impact of any disorder.
