The document provides information on two major classification systems for mental disorders:
1. The ICD (International Classification of Diseases) published by the WHO is used globally to classify all diseases and injuries. Chapter V covers mental disorders. ICD-10 is currently in use.
2. The DSM (Diagnostic and Statistical Manual of Mental Disorders) published by the APA is used primarily in the US to classify mental disorders. The latest version is DSM-5.
While both systems aim to standardize diagnosis, the ICD has broader scope and global use while the DSM is used more by US psychiatrists. Recent editions have increased alignment between the two classifications.
