Cerebrospinal fluid orexin testing in Australians with narcolepsy type 1

Internal Medicine Journal, EarlyView.
Abstract A clinical diagnosis of narcolepsy type 1 can be challenging, particularly in relation to cataplexy. Despite its specificity, cerebrospinal fluid (CSF) orexin testing is under‐utilised in Australasia. We describe the use of CSF orexin testing in 15 clinically indicated patients from two sleep centres, highlighting its utility in the ...

Functional cardiac orexin receptors: role of orexin-B/orexin 2 receptor in myocardial protection [PDF]

Clinical Science, 2018
Orexins/hypocretins exert cardiovascular effects which are centrally mediated. In the present study, we tested whether orexins and their receptors may also act in an autocrine/paracrine manner in the heart exerting direct effects. Quantitative reverse transcription-PCR (RT-PCR), immunohistochemical and Western blot analyses revealed that the rat heart ...

Substitution Patterns After Discontinuation of CNS‐Active Medications in Older Adults in Primary Care

Journal of the American Geriatrics Society, EarlyView.
ABSTRACT Background Little is known about substitution of alternative medications in the context of deprescribing. The objectives were to: (1) determine the frequency of medication substitutions among those who discontinued a central nervous system (CNS)‐active medication, and (2) characterize substitutions as potentially inappropriate (as per the 2023

Orexin/Hypocretin and MCH Neurons: Cognitive and Motor Roles Beyond Arousal

Frontiers in Neuroscience, 2021
The lateral hypothalamus (LH) is classically implicated in sleep-wake control. It is the main source of orexin/hypocretin and melanin-concentrating hormone (MCH) neuropeptides in the brain, which have been both implicated in arousal state switching ...

Narcolepsy and rapid eye movement sleep

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Since the first description of narcolepsy at the end of the 19th Century, great progress has been made. The disease is nowadays distinguished as narcolepsy type 1 and type 2. In the 1960s, the discovery of rapid eye movement sleep at sleep onset led to improved understanding of core sleep‐related disease symptoms of the disease (excessive ...

Ageing‐related modification of sleep and breathing in orexin‐knockout narcoleptic mice

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Narcolepsy type‐1 (NT1) is a lifelong sleep disease, characterised by impairment of the orexinergic system, with a typical onset during adolescence and young adulthood. Since the wake–sleep cycle physiologically changes with ageing, this study aims to compare sleep patterns between orexin‐knockout (KO) and wild type (WT) control mice at ...

Parasomnias and sleep‐related movement disorders induced by drugs in the adult population: a review about iatrogenic medication effects

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Parasomnias and sleep‐related movement disorders (SRMD) are major causes of sleep disorders and may be drug induced. The objective of this study was to conduct a systematic review of the literature to examine the association between drug use and the occurrence of parasomnias and SRMD.
