The effects of PAP on sleep reflect a balance between correcting CHRF-induced sleep disturbances and the potential for therapy itself to disrupt sleep. Given the critical role of sleep in overall health, there are relevant concerns about the effects of PAP usage on sleep architecture. We performed a systematic review and meta-analysis of polysomnographic parameters, using a random-effects model for quantitative analyses. Forty studies were included (n = 1099; 438 OHS, 350 NMD, 175 COPD, 136 unspecified CHRF; 58 % male, age 56.6 ± 8.9 years, body mass index 36.5 ± 11.3 kg/m<sup>2</sup>, arterial carbon dioxide pressure 51.8 ± 5.0 mmHg).

Notably, many BoNT-treated neurological disorders co-occur with sleep disturbances, yet sleep outcomes remain underexplored. This review synthesizes current evidence on sleep outcomes following BoNT treatment of both established neurological indications (e.g., neuropathic pain, chronic migraine, dystonia, spasticity, sialorrhea, hemifacial spasm, bladder dysfunction) and primary sleep disorders (e.g., restless legs syndrome, sleep bruxism, insomnia). As a result, BoNT treatment improves sleep outcomes across both categories, potentially through mechanisms involving modulation of vasomotor tone, hormonal secretion, neural activity, mood, and pain perception. However, larger, rigorously designed randomized controlled trials are essential to definitively confirm these therapeutic effects and elucidate the underlying neurobiological mechanisms.</div></div>","PeriodicalId":49513,"journal":{"name":"Sleep Medicine Reviews","volume":"84 ","pages":"Article 102181"},"PeriodicalIF":9.7,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145267605","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thirty-one studies were identified as eligible and reviewed by three independent researchers. The main findings indicate that chronotype is often under-assessed in school-aged children, with both professionals and parents reporting limited knowledge of children's sleep patterns. Additionally, there is a lack of information in the literature regarding how chronotype, sleep patterns, and vigilance are influenced by latitude and sociocultural factors. Most research on the relationship among the aforementioned variables is focused on adults rather than children. Furthermore, the methods for measuring sleep quality and chronotype were found to be inconsistent, with chronotype and sleep quality often used interchangeably. Based on these findings, further research is needed to explore how chronotype, sleep habits, and cultural or latitudinal factors might predict mental health and cognitive development in children.

Polysomnography (PSG) plays a key role in evaluating motor features of RLS, such as periodic leg movements during sleep (PLMS). This review examines the effects of pharmacological treatments on PSG parameters and sleep architecture in RLS. Dopamine agonists are the most studied, consistently reducing PLMS but offering limited improvements in sleep structure and carrying risks of augmentation with long-term use. In contrast, alpha-2-delta ligands (e.g., pregabalin, gabapentin) improve sleep efficiency and reduce wakefulness, particularly benefiting patients with sensory symptoms or insomnia. Research on opioids and intravenous iron remains limited, though both show potential: opioids may reduce PLMS and improve sleep but raise respiratory safety concerns, while intravenous iron has shown efficacy, especially in pregnant women and children. We also conducted a meta-analysis assessing treatment effects of dopamine agonists on total sleep time, wakefulness after sleep onset, and sleep stage percentages (N1, N2, N3, REM).
