Abstract
Stroke is one of the most important causes of worldwide mortality and morbidity. As it is known that sleep disorders such as obstructive sleep apnea (OSA) could be a risk factor for stroke, stroke could cause sleep disorders that may prolong hospitalization and make rehabilitation difficult. Sleep disorders may also be responsible for patient’s bad prognosis or stroke recurrence if they are not properly managed.
This is a descriptive study that is designed to describe prevalence of sleep disorders after stroke and its severity for a selected number of patients from an outpatient stroke clinic at a time extending to the first three months after stroke through questionnaires. These questionnaires are sleep disorder questionnaire, Pittsburg sleep quality index, Epworth sleepiness scale and Apnea hypo-apnea index.
In this study, sleep disorders are found to be common up to (88%) of the total number of patients. They could be categorized into main four groups; Sleep disordered breathing, parasomnia, hypersomnia and insomnia, respectively according to prevalence. The most common type of them is sleep disordered breathing (SDB) which constitutes a part up to third of the total cases (29.3%). Other sleep disorders the patients have are parasomnia (26.7%), hypersomnia or excessive daytime sleepiness (17.3%) and insomnia (14.7%).
Sleep disorders of those patients were evaluated by Pittsburg sleep quality index which revealed that patients who have a clinically significant sleep disorder, whatever it is, are common up to (61.3%) of the total number of patients. This is severe enough to necessitate medical help and mainly attributed to bad quality of sleep at night or its daytime consequences or both. Patients who have clinically significant hypersomnia, in particular, and need medical help, constitute (20%) of the total number of patients, while symptoms of sleep disordered breathing are ranging from mild to moderate severity.
