Narcolepsy: Pathophysiology, Diagnosis, Management, and Future Directions, a Narrative Review. [PDF]
This visual summary outlines the pathophysiology of narcolepsy, driven by hypocretin loss, and details its clinical diagnosis, current management strategies, and the shift toward future disease‐modifying therapies like orexin agonists and immunomodulation.

Narcolepsy 2025 (with an Australasian perspective). [PDF]
Abstract Narcolepsy is a disorder of central hypersomnolence, which, while uncommon, can carry profound implications for affected individuals. Despite this, it remains under‐recognised within the medical community and presents frequent diagnostic and treatment challenges in the Australasian setting.

Orexin Deficiency in Narcolepsy: Molecular Mechanisms, Clinical Phenotypes, and Emerging Therapeutic Frontiers. [PDF]
Orexin deficiency drives narcolepsy Type 1, leading to excessive daytime sleepiness, cataplexy, and REM intrusions. This review highlights recent advances (2023–2025) in molecular mechanisms, diagnostics, and emerging orexin‐targeted therapies with the potential for disease modification.

Dopamine release in the nucleus accumbens promotes REM sleep and cataplexy
Summary: Patients with the sleep disorder narcolepsy suffer from excessive daytime sleepiness, disrupted nighttime sleep, and cataplexy—the abrupt loss of postural muscle tone during wakefulness, often triggered by strong emotion.

Background Cataplexy is a loss of muscle tone that can lead to postural collapse, disturbing the daily life of narcolepsy patients; it is often triggered by positive emotions such as laughter in human patients.

How are normal sleeping controls selected? A systematic review of cross-sectional insomnia studies, and a standardised method to select healthy controls for sleep research [PDF]
There appears to be some inconsistency in how normal sleepers (controls) are selected and screened for participation in research studies for comparison with insomnia patients.

Activity of putative orexin neurons during cataplexy
It is unclear why orexin-deficient animals, but not wild-type mice, show cataplexy. The current hypothesis predicts simultaneous excitation of cataplexy-inhibiting orexin neurons and cataplexy-inducing amygdala neurons.

Increased immune complexes of hypocretin autoantibodies in narcolepsy. [PDF]
BACKGROUND: Hypocretin peptides participate in the regulation of sleep-wake cycle while deficiency in hypocretin signaling and loss of hypocretin neurons are causative for narcolepsy-cataplexy.

Clinical and Polysomnographic Comparison between Narcolepsy without Cataplexy and Idiopathic Hypersomnia [PDF]
Background and Objective The aim of this study is to compare the clinical, electrophysiological (Polysomnography, PSG; Multiple Sleep Latency Test, MSLT) and biological data (HLA DQB1*0602 typing) in idiopathic hypersomnia with narcolepsy without ...
