The prevalence of SDB after stroke has been noted to be very high, up to 70%, and consists of a higher contribution of central sleep apnea compared to the general population. Recurrent stroke is associated with a higher prevalence of SDB compared to first-time stroke. Contributions to SDB as related to stroke do not appear to have consistencies in terms of location and size of stroke. Untreated SDB can also contribute to stroke risk, with mechanisms involving increased systemic inflammation, prothrombotic biochemical markers, and dysfunction of cerebral autoregulation. Although there are post-hoc subgroup data in a randomized controlled trial suggesting reduction in stroke outcomes when SDB is treated with positive airway pressure, overall there are few studies that have rigorously examined the impact of treatment. Hypersomnia can be treated with modafinil and restless legs syndrome may become manifest due to sleep fragmentation.","PeriodicalId":30275,"journal":{"name":"Sleep Disorders","volume":"277 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90416406","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Expertise in differentiating a benign parasomnia from significant medical disorders in adults and children is important, as is the ability to correctly identify and modify predisposing and precipitating factors. The case presented in this chapter illustrates how making a premature decision based on a small piece of information delayed an important diagnosis and increased the risk of further morbidity. The peak prevalence of sleep terrors is 18 months of age, but they may be seen at any age during childhood. When recurrent sleep terrors recur or develop in adults, evaluation for other primary sleep disorders, including sleep apnea, restless legs, shift work, and sleep deprivation, is warranted, and polysomnography is usually indicated. Identifying and correcting precipitating factors may minimize the recurrence of sleep terrors. Treatment of sleep apnea may greatly reduce the frequency of night terrors and other parasomnias.","PeriodicalId":30275,"journal":{"name":"Sleep Disorders","volume":"407 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76827908","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This chapter reviews the prevalence and pathophysiologic interactions of these conditions, the interplay with associated disorders, and the effects of continuous positive airway pressure therapy on pulmonary hemodynamics. In patients with OSA, chronic effects of repetitive hypoxia as well as comorbidities, including chronic obstructive pulmonary disease and left-sided heart dysfunction, play a role in promoting pulmonary hypertension. Sleep disordered breathing, representing a spectrum of sleep-related breathing disorders inclusive of OSA, is highly prevalent among patients with established pulmonary hypertension. Obstructive events, central sleep apnea, and nocturnal hypoxia are within the spectrum of sleep-related breathing disorders in pulmonary hypertension. The mechanisms for these associations remain speculative.","PeriodicalId":30275,"journal":{"name":"Sleep Disorders","volume":"37 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80910898","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This case additionally emphasizes the importance of sleep in emotional and mental stability, as well as the importance of physicians being well versed in the adverse effects of prescribed and over-the-counter medications. Mirtazapine can induce restless legs syndrome and periodic limb movements in sleep, conditions that can fragment sleep and interfere with cognition. Use of pramipexole has been shown to cause compulsive and impulsive behaviors in patients with restless legs syndrome, Parkinson disease, and multiple system atrophy.
