Abstract W MP60: Prevalence Of Post Stroke Daytime Sleepiness
Background of the study: In patients with stroke, the most common Sleep Disorder are sleep apnea, insomia (30%), and excessive daytime sleepiness. Ischemic stroke patients had 76.8% sleep disorder and hemorrhagic stroke patients had 82.5% sleep disorder. There were several postulated mechanisms on the pathophysiologic effects of sleep disorders on stroke which includes: acute hemodynamic changes during episodes of apnea, decreased cerebral blood flow, and paradoxical embolization, hypercoagulability, hypoxia-related cerebral ischemia, and atherosclerosis. With these several mechanisms, post stroke recovery among patients with post stroke sleep disorder can be altered.
Methodology: A cross sectional study was conducted in Jose Reyes Memorial Medical Center from July 2013 to June 2014. All Medical records and neuroimaging of post stroke patients (≥ 6 months) were reviewed. Those patients with cognitive dysfunction, unable to give consent or unable to understand the study protocol and whose neuroimaging cannot be retrieved were excluded in the study. The interviewer assisted Epworth Sleepiness Scale (ESS) was used in this study to determine daytime sleep propensity.
Results: A total of 130 subjects were included. There were 82 (63%) male and 48(37%) female. The mean age is 58. The variables shown to be significantly associated with ESS were duration of stroke, number of risk factor and type of stroke. The more recent the stroke (specifically shorter than 2.7 years which is the mean), the higher the ESS score. A patient with two risk factors was 4.6x more likely to have an ESS of 10-14 compared to one who has only 1 risk factor. Those who had intracranial bleeding were 2.5 times more likely to have an ESS of 10-14.
Conclusion: Among post stroke patients, the more recent the stroke, the more risk factors present, and those who had intracerebral hemorrhage have higher propensity for daytime sleepiness.
