Characteristics and associated factors of sleeping and cognitive status after ischemic stroke

Abstract

Background: Stroke is a global health concern, with cognitive impairment and sleep disturbances associated with the prognosis of ischemic stroke. There is a lack of research on the prevalence and risk factors of these conditions in Bangladesh. Aim: The study aimed to find out the characteristics of sleeping and cognitive status with their associated factors after ischemic stroke. Methodology: The study design was a cross sectional study that involved 120 conveniently selected participants from the Neurology Department of the Centre for the Rehabilitation of the Paralyzed (CRP), Savar, Dhaka, assessing cognitive status and sleep disturbance, respectively, by using Mini-Mental State Examination (MMSE) and Sleep Quality Scale (SQS) questionnaires. This study was conducted by using SPSS software 20.0 for quantitative descriptive analysis. Results: Among 120 ischemic stroke participants (mean age was 52.94±12.27, 70.8% (n=85) males and 29.2% (n=35) females), the mean total SQS score was 36.58±10.191. Thirty five participants had often poor sleep quality score. Fifty (41.7%) participants had no cognitive problem, while 70 (58.3%) participants had cognitive impairment and among them, 21.7% (n=26) had severe cognitive impairment, 23.3% (n=28) had moderate and 13.3% (n=16) had mild cognitive impairment. This study found significant correlation between the four domains of MMSE (orientation, registration, recall and language) and the ten domains of SQS. Here highly significant associations (p=0.000) were found in between registration domain and recall domain of MMSE with poor sleep makes hard to think; and Registration domain of MMSE with poor sleep makes irritated (p=0.001). Conclusion: Ischemic strokes can cause sleep disturbance and cognitive impairment, affecting rehabilitation and quality of life. Early detection and appropriate care are crucial for minimizing further problems and improving patient outcomes. Key word: Ischemic stroke, Sleep disturbance, Cognitive impairment
