The pathophysiologic aspects of CSA-CSB are discussed, including ventilatory responsiveness and concepts of loop gain, apneic threshold, and narrowing of the carbon dioxide delta gap serving as a predisposing factor. Complexities of the clinical approach are reviewed in terms of clinically contextualizing the findings from a large randomized controlled trial demonstrating increased cardiovascular-specific mortality in patients randomized to adaptive servo ventilation versus controls in those with central-predominant sleep apnea and reduced ejection fraction HF. Potential mechanistic explanations for these findings are reviewed and placed into context with available post hoc analyses from this trial. Treatment options are discussed, including the role of other positive airway pressure (PAP) modalities, supplemental oxygen, relevant medications, and innovative non-PAP therapies such as transvenous phrenic nerve stimulation.","PeriodicalId":30275,"journal":{"name":"Sleep Disorders","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85600745","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. Donepezil can cause hallucinations in patients, which can be difficult to distinguish from hallucinations caused by dementia or Charles Bonnet syndrome; in these cases, establishing a timeline is integral in discovering the etiology.","PeriodicalId":30275,"journal":{"name":"Sleep Disorders","volume":"27 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87136604","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}
