Designed for busy clinicians and trainees alike, Kryger's Sleep Medicine Review: A Problem-Oriented Approach offers a streamlined yet comprehensive method to master the essentials of sleep medicine. Rather than presenting topics by disease, this review book structures learning around common clinical presentations—helping readers think like seasoned diagnosticians. Whether you are preparing for board certification or seeking a practical refresher, the problem-based format facilitates efficient study and real-world application.

Intended Audience

This review volume is aimed at a broad range of healthcare professionals. It is commonly used by physicians preparing for board certification in sleep medicine, as well as by fellows in pulmonary, neurology, and psychiatry programs. Practising clinicians who want to refresh their knowledge will also find it useful. Allied health professionals such as sleep technologists, respiratory therapists, and clinical psychologists specializing in sleep disorders may use this book as a reference. Medical students with an interest in sleep medicine can supplement their coursework with this resource.

Content Coverage

A comprehensive sleep medicine review typically covers all major sleep disorders. Topics include:

• Insomnia: acute and chronic, primary and comorbid, behavioural and pharmacological treatments.
• Sleep-related breathing disorders: obstructive sleep apnea (OSA), central sleep apnea, sleep-related hypoventilation, and positive airway pressure therapy.
• Central disorders of hypersomnolence: narcolepsy type 1 and 2, idiopathic hypersomnia, and Kleine-Levin syndrome.
• Circadian rhythm sleep-wake disorders: delayed sleep phase, advanced sleep phase, shift work disorder, jet lag.
• Parasomnias: NREM-related (confusional arousals, sleepwalking, sleep terrors) and REM-related (REM sleep behaviour disorder, nightmares).
• Sleep-related movement disorders: restless legs syndrome, periodic limb movement disorder, sleep-related bruxism, and rhythmic movement disorder.
• Other topics: sleep in medical disorders (e.g., COPD, heart failure), sleep in neurological disorders (e.g., Parkinson's disease, epilepsy), paediatric sleep medicine, and sleep pharmacology.

Additionally, the book likely includes chapters on sleep evaluation methods such as polysomnography scoring, multiple sleep latency test (MSLT), maintenance of wakefulness test (MWT), and actigraphy. Treatment modalities discussed may include cognitive behavioural therapy for insomnia (CBT-I), continuous positive airway pressure (CPAP), oral appliances, medications, and surgical options.

Understanding the Problem-Oriented Approach

The problem-oriented approach organizes medical knowledge around presenting problems rather than diseases. In sleep medicine, common problems include insomnia, excessive sleepiness, loud snoring, and abnormal movements during sleep. Each problem is explored through a systematic framework: definition, epidemiology, pathophysiology, clinical features, diagnostic approach, and management. This method mimics the clinical workflow and helps learners integrate knowledge from multiple disciplines. Many educators believe this approach improves long-term retention and clinical application.

Benefits of the Problem-Oriented Format

The problem-oriented format offers several advantages. It encourages active learning by presenting cases that require application of knowledge. It helps readers develop differential diagnosis skills, which are crucial in clinical practice. The format also allows for targeted review, as a clinician can quickly find information relevant to a specific patient problem. Many review books incorporate self-assessment questions at the end of each chapter, reinforcing learning and identifying areas needing further study.

How to Use This Book for Exam Preparation

For board preparation, a systematic approach is recommended. Readers can start by reviewing each chapter thoroughly, taking notes on key points. Then, use the self-assessment questions to test recall. It may also be helpful to discuss cases with peers or attend review courses. The problem-oriented approach aligns well with the style of many board exams, which often present clinical vignettes. This book can be used as a primary review resource or as a supplement to a comprehensive textbook.

Kryger's Sleep Medicine Review: A Problem-Oriented Approach is a valuable resource for anyone seeking to master sleep medicine. Its problem-oriented structure facilitates clinical reasoning and efficient review. While it does not replace a full textbook or clinical experience, it serves as an effective tool for consolidation and exam preparation.
