In current months, the NeurologyLive® group has been covering the news on the most recent updates in the clinical care of people with neuromuscular issues, numerous sclerosis, movement issues, sleep issues, and a lot more. For our coverage of sleep issues, our group has spoken with various professionals and highlighted several clinical findings relevant for the populations of individuals with issues such as narcolepsy, insomnia, cataplexy, and numerous other individuals.
For Planet Sleep Day—celebrated on March 17, 2023—the group has culminated some of the largest pieces of news to present updates on new developments in the literature of sleep medicine to spread awareness on the prevention and remedy of sleep issues.

Clinical and Neuropsychological Information on Narcolepsy Shows No Distinction in Comparison of International Networks
A not too long ago published study (NCT05375890) in the Journal of Clinical Sleep Medicine showed nonsignificant variations in clinical and neuropsychological information in the Russian Narcolepsy Network (RN-NN) relative to that previously reported in the European Narcolepsy Network (EU-NN).1 The findings showed a lot more serious and larger percentages of individuals who practical experience cataplexy in Russia, suggesting a low awareness of narcolepsy.
Comparing information with the EU-NN,two the RN-NN had fewer individuals with excessive daytime sleepiness (EDS) as a initial symptom (25.six% vs 43.eight% P = .0014), whereas the percentage of each EDS and cataplexy as a initial symptom was just about twice as higher as in the EU-NN information (67.four% vs 48.eight P = .0013). Notably, the prevalence of serious cataplexy instances was larger in the RN-NN than in the EU-NN information (93.eight% [n = 80] vs 62.six% [n = 829] in EU-NN P = .001).
Sleep paralysis (59.1%, n = 88) and hallucinations (82.%, n = 89 P = .0017) have been present in the RN-NN a lot more frequently than in the European cohort (52.six% [n = 257] and 63.1% [n = 370], respectively). Information with polysomnography and imply sleep latency test (MSLT) in RN-NN are related, despite the fact that observed MSLT scores (four.9 [±2.9] minutes [n = 52] vs three.9 ± three. minutes [n = 927] P = .0193) have been as larger in the Russian cohort.
Narcolepsy Causes Important Effect on Social Connection Wellness in Adolescents, Study Shows
In an exploratory study not too long ago published in the Journal of Clinical Sleep Medicine, findings revealed an overarching theme that adolescents and their parents practical experience difficulty in attempting to balance narcolepsy symptom management with meaningful social engagement.three In the study, symptoms of daytime fatigue and cataplexy have been the most important and generally discussed amongst adolescents and their parents as possessing an influence on social relationships.
Notably, adolescents reported feeling frustrated by their sleep disorder impacting their social lives such as regularly needing to strategy ahead with their sleep schedule. Also, each adolescents and their parents expressed the will need for health-related providers to much better realize their altering priorities, validate social limitations, and present a lot more data about the social implications of situation and remedy.
Adolescents among the ages of 12 and 17 years old with narcolepsy and their parents completed a semistructured interview individually among July 2021 and December 2021. Participants have been integrated if they had a confirmed diagnosis of narcolepsy kind 1 (n = 12 85.7%) or kind two (n = two 14.three%) working with polysomnography/MSLT or other testing and have been fluent in English. Information records have been extracted, primarily based on their narcolepsy medication strategy and Epworth Sleepiness Scale (ESS) score three months prior to the interview date, from Boston Children’s Hospital. Of note, three individuals had a health-related record from outdoors the hospital. Interview transcripts have been analyzed working with a multistage thematic evaluation.
Titration Prevalent in Solriamfetol, Leads to Improvements in Daytime Sleepiness
Solriamfetol (Sunosi Axsome Therapeutics), an FDA-authorized medication for EDS, is generally initiated at 75 mg/day, with titration frequent, according to the SURWEY study assessing genuine-planet doctor tactics.four Following initiation, individuals skilled improvements in ESS scores, and most individuals perceived improvement in their EDS status.
The most frequent beginning doses all round have been 75 mg/day (69%) or 150 mg/day (20%), with most of the remaining individuals initiated at 37.five mg. Virtually half (43%) of individuals had their remedy titrated, with 90% finishing titration as prescribed. Titration was most generally completed inside 7 days (57%). For individuals who changed remedy, switching to solriamfetol was managed working with an abrupt method for 88% of individuals, an overlapping (tapered) method for 9% of individuals, and an unknown method for two% of individuals.
Retrospective chart critiques from 70 German adults with EDS and narcolepsy have been collected by investigators, with individuals classified as either changeover (n = 43 61%), add-on (n = 19 27%), or new-to-therapy (n = eight 11%) subgroups, primarily based on current EDS remedy. The imply age of the cohort was 36.9 (±13.9) years and imply physique mass index was 26.7 (SD, five.two) kg/m. A lot more than half (57%) had cataplexy, and most (84%) have been treated in sleep centers.
Alterations in Sleep Architecture, Comorbidities Observed in Lengthy-Term Therapy With Sodium Oxybate
Findings from a little-scale, longitudinal study assessing individuals with narcolepsy with cataplexy (NT1) showed that just after three years of remedy with low to medium doses of sodium oxybate, there have been important variations in sleep structure and an raise in comorbidities that led to drug withdrawal.five
To the study authors know-how, this was the longest recorded trial evaluating the impact of sodium oxybate on sleep architecture and comorbidity with video-polysomnography. The trial featured 23 adults with NT1 who have been treated with an initial nocturnal dose of four.five g of sodium oxybate, with sleep parameters compared just after six months (FU-1), 1 year (FU-two), and three years (FU-three) of uninterrupted remedy.
Findings on video polysomnography showed an raise in stage N3 in the initial sleep cycle and a REM-onset in 90% of individuals just after the administration of the initial dose. When comparing the time spent in the various sleep stages among FU-1 and FU-two, individuals elevated the time spent in stage N2 (z = –2.17 P = .03). At FU-three, there was a important elevated observed in the time spent in stage N1 (z = –2.09 P = .03). Moreover the time spent in stages N1 and N2 have been considerably longer in the most recent stick to-up than at FU-1 (z = –2.36 P = .001).
While Often Made use of, Complementary and Option Medicine Ineffective to Treat Narcolepsy
Findings from a current survey of 254 German individuals with narcolepsy showed that biologically primarily based therapies have been the most regularly utilised in complementary and option medicine (CAM) subgroups (76%) on the other hand, their influence is restricted. Although on these medicines, individuals nevertheless felt the will need to boost their symptoms, sleepiness, and psychological properly becoming.six
Amongst 33% of CAM customers (n = 84), vitamins/trace components (54%), homoeopathy (48%) and meditation (39%) have been utilised most regularly. Fifty-4 customers (64%) described CAM as beneficial. CAM customers a lot more regularly reported side effects from earlier medication (P = .001). Notably, CAM customers reported a lot more regularly not complying with pharmacological remedy than nonCAM customers (21% vs. eight% P = .024).
When a week or a lot more, 75% of CAM customers utilized CAM and whereas only 23% of customers did only as soon as a month or a lot more. Twenty-3 % of individuals who did not take any traditional pharmacological remedy prior (n = 38) reported present CAM use. Twenty-seven % of individuals utilised each traditional medicine and CAM at the similar time (n =69). Amongst these who reported previous or present CAM use, 73% reported possessing automatic behavior (n = 61 vs. n = 97 nonCAM customers), 68% reported hypnagogic/hypnopompic hallucinations (n = 57 vs. n = 91 nonCAM customers), and 70% reported nightmares (n = 59 vs. n = 97 nonCAM customers).
