The Relationship Between Obstructive Sleep Apnea and Ruptured Intracranial Aneurysms

Study Objectives:The role of obstructive sleep apnea (OSA) in the overall outcome of ruptured intracranial aneurysms (RIAs) is unknown. We have investigated the role of OSA in overall outcome of RIAs.Methods:Data from 159 consecutive patients were retrospectively reviewed. A chi-square test and regression analysis were performed to determine the significant difference. A value ofP

Conclusions: Embolism associated with asymptomatic carotid stenosis shows circadian variation with highest rates 4–6 h before midday. This corresponds with peak circadian incidence of stroke and other vascular complications. These and ASED Study results show that monitoring frequency, duration, and time of day are important in ES detection. Introduction Transcranial Doppler (TCD) detected microembolism in the ipsilateral middle cerebral artery (MCA) may help stratify the risk of stroke and other arterial disease complications in persons with advanced (≥60%) asymptomatic carotid stenosis. If so, this techniqu...

Conclusion. Modafinil is a central nervous system stimulant with well-established effectiveness in the treatment of narcolepsy and shift-work sleep disorder. There is conflicting evidence about the benefits of modafinil in the treatment of fatigue and EDS secondary to TBI. One randomized, controlled study states that modafinil does not significantly improve patient wakefulness, while another concludes that modafinil corrects EDS but not fatigue. An observational study provides evidence that modafinil increases alertness in fatigued patients with past medical history of brainstem diencephalic stroke or multiple scleros...

Introduction: Stroke or Cerebrovascular Disease is a serious neurological disorder and is the second leading cause of death globally. Apart from the well-known modifiable risk factors for stroke like diabetes, hypertension and ischemic heart disease, Obstructive Sleep apnea (OSA) is emerging as an independent and eminently modifiable risk factor. The reported prevalence rate of OSA in stroke patients in various studies ranges from 30-80%. This prospective study was undertaken over a period of 20 months to determine the prevalence of OSA in newly diagnosed stroke patients.

Introduction: Obstructive sleep apnea (OSA) is characterized by episodic, complete or partial nocturnal cessation of breathing with associated oxygen desaturation. It is also a known risk factor for systemic illnesses like hypertension, ischaemic heart disease and stroke. A major mechanism which triggers many of the systemic complications of OSA is hypoxemia which is measured in the hypopnea index component of the apnea-hypopnea index (AHI) and oxygen desaturation index. In the present study, we have attempted to find the association between various OSA indices and prevalent comorbidities among patients evaluated in Sleep Clinic.

In addition to a significant negative effect on quality of life, serious health consequences are associated with obstructive sleep apnea syndrome (OSAS), including hypertension, ischemic heart disease, stroke, neurocognitive abnormalities, and mental health problems. Treatment can range from conservative measures to surgery, with oral appliances (OAs) becoming a popular option. These devices are noninvasive and can be effective, depending on patient compliance. Appliances can be divided into mandibular advancement devices, tongue-retaining devices, and soft palate−lifting devices.

Abstract Obstructive sleep apnea (OSA) is common in the general population and highly prevalent in patients with cardiovascular disease. In this paper, we review (1) the pathophysiological mechanisms of OSA that may causally contribute to cardiovascular disease; (2) current evidence regarding the association between OSA and hypertension, stroke, ischemic heart disease, heart failure, atrial fibrillation, and cardiovascular mortality; and (3) the impact of continuous positive airway pressure (CPAP) treatment on cardiovascular risk factors and outcomes. We emphasize the importance of obesity as a comorbidity of OSA...

This article describes 2 independent studies that worked collaboratively to fill these gaps. The populations, design features, and relative benefits/challenges of the 2 studies (SleepTight and BestAIR) are described. Both studies were encouraged to have multidisciplinary teams with expertise in behavioral interventions to improve PAP compliance. Both studies provide key information that will be useful to the research community in future large-scale, event-driven, randomized trials to evaluate the efficacy and/or effectiveness of strategies to identify and treat significant OSA for decreasing risk of major adverse cardiovas...

This article reviews the available medical literature on PMs in order to justify the utility of PMs in the diagnosis of OSA, especially in resource-poor, high-disease burden settings. The published practice parameters for the use of these devices have also been reviewed with respect to their relevance in the Indian setting.

Abstract Obstructive sleep apnea syndrome (OSAS) is a risk factor for cardiovascular events. However, it is unclear how OSAS contributes to the events. We investigated the impact of non-dipping on the incidence of cardiovascular events in a retrospective cohort study comprising 251 patients with OSAS. OSAS was diagnosed by overnight polysomnography and all patients underwent 24-h ambulatory blood pressure monitoring. Non-dipping was diagnosed when reduction in sleep blood pressure was
