Nocturnal sleep-related scratching disorder as a possible variant of NREM arousal disorder: Clinical features and polysomnographic study of four newly reported cases.
A clinical variant of NREM arousal disorder is described manifesting with predominantly injurious, and exclusively sleep-related scratching without any conscious awareness, and without a history of dermatologic disease. Four patients were clinically evaluated and underwent videopolysomnography (vPSG…
Sodium-relevant comorbidity risk factors are highly prevalent in individuals with narcolepsy or idiopathic hypersomnia.
Individuals with narcolepsy or idiopathic hypersomnia (IH) present with a high comorbidity burden that may confer elevated risk for negative clinical outcomes associated with excess sodium intake. This study characterized the prevalence and profiles of sodium-relevant comorbidity risk factors among…
Assessment of readiness in the diagnosis and management of central disorders of hypersomnolence: A survey of sleep medicine program directors and fellowship graduates.
Central disorders of hypersomnolence (CDH), including narcolepsy, idiopathic hypersomnia, and recurrent hypersomnia, are rare conditions that pose challenges in sleep medicine fellowship training. Limited exposure to these disorders, variability in training experiences, and growing complexity of dia…
Sleep and Migraine Interactions in Episodic and Chronic Migraine: A Hospital-Based Cross-Sectional Study.
Migraine and sleep disturbances frequently coexist. The study aimed at characterizing sleep disturbances and their association with migraine characteristics. In this cross-sectional study, 253 patients with migraine [patients with episodic migraine (pEM) = 103 and patients with chronic migraine (pCM…
Boundary-Dependent Sleep-Wake Dysregulation in Idiopathic Hypersomnia.
Idiopathic hypersomnia (IH) presents with excessive daytime sleepiness (EDS) despite apparently preserved nocturnal sleep, challenging traditional models of hypersomnolence based on sleep loss or fragmentation. We aimed to test the hypothesis that EDS in IH reflects excessive stabilization of the sl…
The Italian registry for narcolepsy and central disorders of hypersomnolence (ReN&IS): Baseline clinical and diagnostic findings.
Central disorders of hypersomnolence, a wide and heterogeneous group of neurological disorders including narcolepsy type 1 (NT1), narcolepsy type 2 (NT2), and idiopathic hypersomnia (IH), are chronic, rare, under-recognized, and disabling conditions characterized by excessive daytime sleepiness (EDS…
Comparison of heart rate responses at respiratory event termination in children referred for assessment of hypersomnolence.
Adult studies have linked disorders of hypersomnolence to impaired heart rate (HR) control. We examined HR changes during obstructive and central respiratory events in children referred for assessment of hypersomnolence compared to controls. 20 children diagnosed with narcolepsy, 7 with idiopathic h…
The purpose of this article is to provide an overview of how to evaluate, diagnose, and manage patients with hypersomnia disorders. The extended-release formulation of sodium oxybate to treat narcolepsy with a dosage of once a night, rather than twice a night, was approved in 2023 for adults and in…
