The Importance of a Comprehensive Mental Health Framework

To begin with, it is essential to recognize that mental disorders are medical conditions that affect mood, cognition, and behavior. These disorders vary in severity and duration, ranging from mild, situational symptoms to chronic, debilitating illnesses. Therefore, mental health professionals rely on standardized classification systems—specifically the DSM-5 mental disorders and the ICD-11 mental health disorders—to diagnose and treat these conditions effectively.

The DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition), published by the American Psychiatric Association, is primarily used in the United States. Conversely, the ICD-11 (International Classification of Diseases, 11th Revision), developed by the World Health Organization, is utilized globally and integrates mental and physical health conditions into a single system. Having access to an all mental disorders list provides clarity in diagnosis, improves treatment planning, and fosters more accurate public awareness.
