[Feeding and eating disorders in ICD-11]

Area of Science:

• Psychiatry
• Clinical Psychology
• Medical Diagnostics

Background:

• The International Classification of Diseases (ICD) provides a standardized system for classifying diseases and health problems.
• Previous versions of ICD have guided the diagnosis and classification of feeding and eating disorders.
• There is a need for updated classifications that reflect current understanding and clinical practice in eating disorders.

Purpose of the Study:

• To describe the revisions made to the Feeding and Eating Disorders chapter in the ICD-11.
• To compare the ICD-11 chapter with the previous ICD-10 classification.
• To highlight the inclusion of new diagnoses, specifically avoidant/restrictive food intake disorder (ARFID) and binge-eating disorder (BED).

Main Methods:

• Comparative analysis of the ICD-11 Feeding and Eating Disorders chapter against ICD-10.
• Review and description of revised diagnostic guidelines for each disorder.
• Commentary on the integration of novel diagnostic categories.

Main Results:

• ICD-11 introduces a lifespan approach to feeding and eating disorders.
• Culture-related guidance has been incorporated for each disorder.
• New diagnoses, avoidant/restrictive food intake disorder (ARFID) and binge-eating disorder (BED), are now included.

Conclusions:

• The ICD-11 represents a significant advancement in the classification of feeding and eating disorders.
• The updated framework offers improved diagnostic criteria and cultural considerations.
• The inclusion of ARFID and BED addresses previously unmet diagnostic needs.
