Which of the following diseases are included in Chapter 06 of ICD-11?

Appeared in: BTSC Staff Nurse 31 July-2025

Explanation

Chapter 06 of the ICD-11 is officially titled 'Mental, behavioural or neurodevelopmental disorders'.
This classification correctly groups together conditions primarily related to psychiatry and psychology.
Examples of disorders in this chapter include neurodevelopmental disorders (e.g., autism), schizophrenia, mood disorders (e.g., depression), and anxiety disorders.

Why Other Options Were Wrong

Option B: This category is incorrect for Chapter 06. Conditions related to sexual health have been grouped into a new, separate chapter in ICD-11.
Option C: This is incorrect. While sleep-wake disorders were previously under mental health in ICD-10, they have been moved to their own distinct chapter in ICD-11 to recognize their unique physiological basis.
Option D: This is incorrect. Diseases of the nervous system are distinct from mental and behavioral disorders and are classified in a separate chapter.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain ICD-11 Chapter Classification as background academic context rather than a clinical decision trigger.
Accurate knowledge of ICD-11 chapters is crucial for nurses for correct medical coding, which directly impacts hospital billing, insurance claims, and public health statistics.
Proper documentation using correct ICD codes ensures clear and standardized communication among interdisciplinary healthcare providers, supporting continuity of care and clinical research.
In the Indian healthcare system, correct coding is vital for reporting to national health registries and for tracking disease prevalence and outcomes.

How to Approach the Question

This is a factual recall question that tests your knowledge of a standard medical classification system.
First, identify the key elements of the question: 'ICD-11' and 'Chapter 06'.
The task is to match the chapter number with the correct disease category from the given options.
Recall the basic structure of the ICD-11. If you don't know the exact chapter, try to remember the logical groupings.
Evaluate each option. 'Mental, behavioral or neurodevelopmental disorders' is a major category that logically fits into its own chapter.
Eliminate other options by associating them with different areas of medicine. For example, 'diseases of the nervous system' (neurology) is distinct from 'mental disorders' (psychiatry).
