Incidence and Types of Sleep Disorders in patients with Stroke

Abstract

2 i ntroduction. Sleep disorders (SD) after stroke (stroke) are common occurrences, and most often in sleep apnea, insomnia and daytime sleepiness. Goals. Research goals were to determine the types of SD and their frequency in patients with stroke in relation to the type of stroke and side of lesion. Materials and methods. The study analyzed 200 patients with acute stroke hospitalized in the Clinic of Neurology, University Clinical Centre Tuzla in the period from 1st August 2007 to 1st June 2008. All patients have confirmed the existence of stroke by computerized tomography. SD was verified according to the General Curriculum of sleep, the Berlin questionnaire and Epvort scale. Stroke, by type, were divided into hemorrhagic and ischemic, and the localization of the stroke to right and left cerebral hemispheres. Results. Of the total number of respondents, 78% had SD. Very serious level of SD had 42% of respondents, 20% moderate, and 16% of medium-severe degree. There was no statistically significant differences in the frequency of SD among patients with ischemic and hemorrhagic stroke (76.8%: 82.5%, p=0.58). In relation to the side of lesion there was more patient with SD and stroke in the right cerebral hemisphere, but there were no statistically significant differences (39.5%: 33%, p=0.1). According Epvort scale sleep apnea and snoring was present in 86%, daytime sleepiness in 49.5% and narcolepsy 0.5%. Conclusions. Sleep disturbance as a neuropsychological disorder has a significant incidence in the acute phase of stroke. SD is slightly more common in hemorrhagic stroke and stroke in the right hemisphere. Sleep Apnea and snoring are the most common types of SD in patients with stroke.

Sex differences in sleep: impact of biological sex and sex steroids

“…One prevailing theory with strong supportive evidence is that sleep serves a restorative function for the brain and body. Chronic insufficient sleep is a risk factor for a variety of psychological [9][10][11][12][13], neurological [14][15][16][17][18][19] and neurodegenerative pathologies [16], as well as cardiovascular and metabolic dysfunctions [20][21][22][23][24]. More recent findings from clinical studies reveal that women suffering from sleep disturbances and insufficient sleep are at greater risk compared with men for mood disorders such as depression [25], as well as metabolic [26] and cardiovascular dysfunction [23,[27][28][29].…”

Nocturnal Deterioration after Ischemic Stroke and Autonomic Dysfunction: Hypothesis and Implications

“…The specific syndromes that are frequent companions of stroke and relate to risk for stroke and mortality are OSA (50-70%) and excessive daytime sleepiness (EDS, 20-40%) [17,18,19]. As a cerebral bioelectrical phenomenon, sleep is represented by two cycling states that are distinguished by the presence or absence of rapid eye movements (REM) [20].…”

Research of Sleep Disorders in Patients with Acute Cerebral Infarction

“…14,[18][19][20] Our results showed TST, S1, S31S4, and PSQI reduced significantly (P , .05) in the experimental group, whereas WASO, ESS, REM, SL, and RL increased significantly (P , .05), indicating less sleep time. Structure of SD and lower SE may course excessive sleep.…”

“…These results are consistent with those of previous reviews. 15,20 Compared with the anterior circulation group, S31S4 and REM increased significantly in the posterior circulation group. Researchers further divided the experimental group into 4 groups as in Table 5: when compared with the other 3 groups, sleep quality of the cerebral infarction group was the most poor (P , .05).…”
