International classification of sleep disorders-third edition: highlights and modifications

Area of Science:

• Sleep Medicine
• Neurology
• Psychiatry

Background:

• The American Academy of Sleep Medicine's manual of sleep disorders nosology is a critical reference.
• Previous editions, like ICSD-2, established a foundational classification system.
• International collaboration is key to standardizing sleep disorder diagnoses.

Purpose of the Study:

• To review the major features and changes in the newly released third edition of the International Classification of Sleep Disorders (ICSD-3).
• To discuss the rationales behind the modifications in the ICSD-3.
• To highlight the ICSD-3 as the key reference work for diagnosing sleep disorders.

Main Methods:

• Review of the International Classification of Sleep Disorders, third edition (ICSD-3).
• Analysis of modifications to the nosology of specific sleep disorders, including insomnia, narcolepsy, and parasomnias.
• Discussion of the underlying rationales for the updated classifications.

Main Results:

• The ICSD-3 retains seven major categories: insomnia, sleep-related breathing, central disorders of hypersomnolence, circadian rhythm sleep-wake, sleep-related movement, parasomnias, and other sleep disorders.
• Significant revisions have been implemented in the classification of insomnia, narcolepsy, and parasomnias.
• The manual serves as the primary reference for sleep disorder diagnosis, updated in cooperation with international sleep societies.

Conclusions:

• The ICSD-3 represents a significant revision in sleep disorder classification.
• Understanding these changes is crucial for accurate diagnosis and research in sleep medicine.
• The updated manual facilitates a more refined approach to diagnosing and managing sleep disorders globally.
