Insomnia Subtypes and the Subsequent Risks of Stroke: Report From a Nationally Representative Cohort Clinical Sciences
Conclusions— Insomnia predisposes individuals to increased risk of stroke and this association is profound among young adults. Our results underscore the clinical importance of identifying and treating insomnia. A novel behavioral intervention targeting insomnia that may prevent stroke should be explored.

Obstructive Sleep Apnea in Acute Stroke: A Role for Systemic Inflammation Clinical Sciences
Conclusions— Use of bed-side somnography technology revealed that in an unselected sample of patients with acute ischemic stroke, almost 90% had sleep-disordered breathing with third having severe form of the disorder. Sleep-disordered breathing was associated with significantly increased levels of inflammatory biomarkers, providing possible pathophysiological explanation of OSA-associated stroke risk. These results warrant prospective screening of patients with stroke for the presence of sleep-disordered breathing and lay the rationale for an interventional trial.

Noninvasive Ventilatory Correction in Patients With Acute Ischemic Stroke Brief Report
Conclusions—NIVC seems to be associated with greater short-term neurological improvement in acute ischemic stroke patients with obstructive sleep apnea. This finding deserves further investigation within the settings of an adequately powered, sham-control, randomized clinical trial.

Stroke in the Young: Etiologies and Risk Factors (P7.124)
CONCLUSIONS: Stroke in the young shares many of the same common modifiable risk factors as stroke in the elderly including hypertension, hyperlipidemia, diabetes, and tobacco abuse. Other unique disease processes also contribute to stroke in this age group, often less modifiable. Given the devastating morbidity and mortality of stroke in this age group, a larger public health effort for primary and secondary prevention of stroke in the young should be aggressively pursued.Disclosure: Dr. Govind has nothing to disclose.

Over-the-counter and Prescription Sleep Medication and Incident Stroke: The REasons for Geographic And Racial Differences in Stroke Study
Conclusions: Over-the-counter sleep medication use may independently increase the risk of stroke beyond other risk factors in middle-aged to older individuals with no history of stroke.

Role of sleep-disordered breathing and sleep-wake disturbances for stroke and stroke recovery
Conclusions: SDB and SWD increase the risk of stroke in the general population and affect short- and long-term stroke recovery and outcome. Current knowledge supports the systematic implementation of clinical procedures for the diagnosis and treatment of poststroke SDB and SWD on stroke units.

Obstructive Sleep Apnea and Stroke: Determining the Mechanisms Behind their Association and Treatment Options
AbstractSleep-disordered breathing (SDB) can be a sequela of stroke caused by vascular injury to vital respiratory centers, cerebral edema, and increased intracranial pressure of space-occupying lesions. Likewise, obstructive sleep apnea (OSA) contributes to increased stroke risk through local mechanisms such as impaired ischemic cerebrovascular response and systemic effects such as promoting atherosclerosis, hypercoagulability, cardiac arrhythmias, vascular-endothelial dysfunction, and metabolic syndrome. The impact of OSA on stroke outcomes has been established, yet it receives less attention in national guidelines on st...

Self-reported Sleep Duration in Relation to Incident Stroke Symptoms: Nuances by Body Mass and Race from the REGARDS Study
Background: To determine, among employed persons with low risk for obstructive sleep apnea (OSA), if sleep duration is associated with incident stroke symptoms, independent of body mass index (BMI), and if sleep duration mediates racial differences in stroke symptoms.Methods: In 2008, 5666 employed participants (US blacks and whites, ≥45 years) from the longitudinal and nationally representative Reasons for Geographic And Racial Differences in Stroke study self-reported their average sleep duration. Participants had no history of stroke, transient ischemic attack, or stroke symptoms and were at low risk for OSA. After ...

Impact of obstructive sleep apnea on cardiac organ damage in patients with acute ischemic stroke
Background and purpose: Both obstructive sleep apnea (OSA) and cardiac organ damage have a crucial role in acute ischemic stroke. Our aim is to explore the relationship between OSA and cardiac organ damage in acute stroke patients. Methods: A total of 130 consecutive patients with acute ischemic stroke were enrolled. Patients underwent full multichannel 24-h polysomnography for evaluation of OSA and echocardiography to evaluate left ventricle (LV) mass index (LV mass/BSA, LV mass/height2.7), thickness of interventricular septum (IVS) and posterior wall (LVPW), LV ejection fraction and left atrium enlargement. Informat...

Stroke Volume Predicts Nocturnal Hypoxemia in the Acute Ischemic Stroke after Intravenous Thrombolysis
The Goal: The aim of the study was to investigate whether stroke volume or the presence of ischemic stroke lesion on follow-up computed tomography 1 day after admission had association with sleep apnea among ischemic stroke patients undergoing thrombolysis. Materials and Methods: We prospectively recruited 110 consecutive ischemic stroke patients and performed computed tomography on admission and after 24 hours after intravenous thrombolysis. Stroke volume was measured from post-thrombolysis computed tomography scans.

Sleep Apnea Treatment After Stroke (SATS) Trial: Is It Feasible?
Sleep apnea affects more than half of patients with acute ischemic stroke and is associated with poor stroke outcome. This pilot study assessed the feasibility of a randomized, sham-controlled continuous positive airway pressure (CPAP) trial in subjects with acute ischemic stroke. Subjects identified with sleep apnea based on an apnea-hypopnea index ≥5 on overnight polysomnography or portable respiratory monitoring within 7 days of onset of stroke symptoms were randomized to receive active or sham CPAP for a 3-month period. Objective usage was ascertained by compliance data cards. Subjects, treating physicians, and outco...

Hypoglossal nerve dysfunction and sleep-disordered breathing after stroke
Conclusions: Acute ischemic stroke patients have a high prevalence of hypoglossal nerve dysfunction. Further studies are needed to explore whether hypoglossal nerve dysfunction may be a cause or consequence of SDB in stroke patients and whether this association can provide further insight into the pathophysiology of SDB in this population.
