Narcolepsy: Comorbidities, complexities and future directions.

Patients with narcolepsy live with a lifelong sleep-wake disorder, impairing their quality of life, productivity, educational and employment outcomes. Clinicians are becoming aware that a significant aspect of the burden of this disease relates to frequent comorbid conditions, including aspects of the patient's emotional, metabolic, sleep and immune health. This review explores the literature describing the comorbidities seen in patients with narcolepsy, to enhance understanding of these often complex presentations.

Prospective cohort study to evaluate the accuracy of sleep measurement by consumer-grade smart devices compared with polysomnography in a sleep disorders population.

Objectives: Consumer-grade smart devices are now commonly used by the public to measure waking activity and sleep. However, the ability of these devices to accurately measure sleep in clinical populations warrants more examination. The aim of the present study was to assess the accuracy of three consumer-grade sleep monitors compared with gold standard polysomnography (PSG).

Validation of the self-administered version of the international Restless Legs Syndrome study group severity rating scale - The sIRLS.

Introduction: The International Restless Legs Study Group (IRLSSG) has developed the IRLS (International Restless Legs Syndrome Severity Scale) and validated it as a clinician/researcher administered scale to be used when both patient and examiner are present. The IRLSSG recognized the need for a self-completing scale that can be used economically in clinical practice and in large population-based studies. In this study the validity and the reliability of the IRLS as a self-administered scale (sIRLS) is assessed.

The DSM-5 Self-Rated Level 1 Cross-Cutting Symptom Measure identifies high levels of coexistent psychiatric symptomatology in patients referred for insomnia treatment.

Purpose: Referrals to sleep psychology services, even for a perceived single problem such as insomnia, can present with complex, coexistent psychiatric symptoms and comorbid disorders. This study aimed to assess the feasibility of implementing the DSM-5 Self-Rated Level 1 Cross-Cutting Symptom Measure (CCSM) into a sleep psychology clinic to identify coexistent psychiatric symptomatology in insomnia referrals.

Patients And Methods: Patients were 50 consecutive referrals to a private sleep psychology service within a sleep disorders center in Melbourne, Australia.
