“…Sleep paralysis is often accompanied by HHG, which resembles dreams and occurs during the period of falling asleep [11]. Sleep paralysis and HHG are products of "sleeponset REM" (SOREMP), a REM stage that occurs earlier than normal when the patient is still partially conscious [4,11]. The emotional experience of sleep paralysis with hallucinations often involves fear, terror, and panic.…”

“…It is estimated that the frequency of NT2 is 20.5/10,000 and NT1 is 0.02% -0.18% in the US and Western European populations and 0.16% -0.18% in the Japanese populations [3]. Narcolepsy is manifested by excessive daytime sleepiness (EDS), hallucinations and sleep paralysis [4]. Cataplexy is a sudden loss of muscle tension during wakefulness caused by especially intense emotions for example anger, excitement, or those leading to laughter.…”

“…This condition is known as "sleep paralysis" [3,11]. These phenomena -cataplexy, hallucinations and sleep paralysis are categorised as REM dissociation phenomena, characterised by the occurrence of REM sleep dreams without concurrent REM phenomena or the loss of muscle tone during wakefulness [4]. One of the first descriptions of narcolepsy with cataplexy originates from German authors Westphal in 1877 [12] and Fisher in 1878 [13].…”

Introduction: Narcolepsy (NT) can manifest as excessive daytime sleepiness (EDS), cataplexy, hypnagogic (HHG) and hypnopompic (HHP) hallucinations, sleep paralysis, orgasmolepsy – all of which may affect patients' functioning. The aim of the study was to determine the impact of NT, specific sexual dysfunctions and drugs used in NT on sex life. Materials and methods: A narrative review was conducted, using keywords: narcolepsy, sexual dysfunctions, medications in narcolepsy from repository inception to March 17, 2024 searching PubMed/MEDLINE, Google Scholar, Crossref, Cochrane databases. The quality of the reviewed articles was assessed using the Scale for the Assessment of Narrative Review Articles (SANRA). Results: Sexual activity and satisfaction are reduced in up to 81.1% of patients. There are often multiple co-occurring autonomic dysregulations in patients, including the genitourinary system, causing sexual dysfunction (erectile dysfunction in 48% of men; vaginal lubrication in 81% of women). Orgasmolepsy negatively affects sexual and social relationships in more than 1⁄3 of respondents. Sleep paralysis can be accompanied by HHG, which often present the impression of sexual assault and harassment. They may cause anxiety, post-traumatic stress disorder (PTSD) features, depressed mood, in extreme cases leading to suicide attempts. Of the drugs used in NT, only methylphenidate can increase libido and reduce erectile dysfunction in NT. Conclusions: Orgasmolepsy, sexual and autonomic dysfunction in NT significantly reduce patients' quality of sex life. Sleep paralysis with sexual HHG can reduce psychological well-being. A holistic intervention approach, using behavioural interventions, cognitive-behavioural therapy, education of the patient and their loved ones, is crucial in the treatment of sexual difficulties. Keywords: narcolepsy, sexual dysfunctions, medications in narcolepsy

BackgroundOne of the challenges in bipolar disorder (BD) lies in early detection of the illness and its recurrences, to improve prognosis. Sleep disturbances (SD) have been proposed as reliable predictive markers of conversion. While preliminary studies have explored the relationship between SD and the onset of mood episodes, the results remain heterogeneous and a few have specifically examined patients' perception of prodromal symptoms and their progression until the episode occurs. Identifying prodromes represents a crucial clinical challenge, as it enables early intervention, thereby reducing the severity of BD. Therefore, the objective of this study is to better characterize and evaluate the progressive nature of SD as prodromal symptoms of mood episodes, and patients' perception of it.MethodsPatients diagnosed with BD, either hospitalized or seeking treatment for a (hypo)manic or depressive episode benefited from standardized questionnaires, structured interviews, and self‐report questionnaires to evaluate SD prior to the current episode, as well as sociodemographic and clinical information.ResultsOut of the 41 patients included, 59% spontaneously reported SD prior to the episode, appearing 90 days before depression and 35 days before mania (pre‐indexed/spontaneous reports: 51.22% insomnia complaints, 4.88% hypersomnolence complaints, 7.32% parasomnias, 2.44% sleep movements). After inquiry about specific SD, the percentage of patients reporting prodromal SD increased significantly to 83%, appearing 210 days before depression and 112.5 days before mania (post‐indexed reports: 75.61% presented with insomnia complaints appearing 150 days before depression and 20 days before mania, 46.34% had hypersomnolence complaints appearing 60 days before depression, 43.9% had parasomnias appearing 210 days before depression and 22.5 days before mania, 36.59% had sleep movements appearing 120 days before depression and 150 days before mania). Of note, bruxism appeared in 35% of patients before mania, and restless legs syndrome in 20% of patients before depression.ConclusionThis study highlights the very high prevalence of SD prior to a mood episode in patients with BD with differences between depressive and manic episodes. The more systematic screening of sleep alterations of the prodromal phase improved the recognition and characterization of different symptoms onset by patients. This underscores the need for precise questioning regarding sleep patterns in patients, to better identify the moment of transition toward a mood episode, referred to as "Chronos syndrome". The study emphasizes the importance of educating patients about the disorder and its sleep prodromal symptoms to facilitate early intervention and prevent recurrences.

Sleep medicine is an ambitious cross-disciplinary challenge, requiring the mutual integration between complementary specialists in order to build a solid framework. Although knowledge in the sleep field is growing impressively thanks to technical and brain imaging support and through detailed clinic-epidemiologic observations, several topics are still dominated by outdated paradigms. In this review we explore the main novelties and gaps in the field of sleep medicine, assess the commonest sleep disturbances, provide advices for routine clinical practice and offer alternative insights and perspectives on the future of sleep research.
