Stroke causes a transient imbalance of interhemispheric information flow in EEG during non-REM sleep
Frederic Zubler Andrea Seiler Thomas Horvath Corinne Roth Silvia Miano Christian Rummel Heidemarie Gast Lino Nobili Kaspar A. Schindler Claudio L. Bassetti 《Clinical neurophysiology》2018,129(7):1418-1426
Objective
Large-scale connectivity, especially interhemispheric connections, plays a crucial role for recovery after stroke. Here we used methods from information theory to characterize interhemispheric information flow in wake- and sleep-EEG after cerebral ischemia.Methods
34 patients with unilateral ischemic stroke were included. Symbolic Transfer Entropy (STE) was applied between bipolar EEG signals on the left and the right cerebral hemisphere during polysomnographic recordings in the acute phase and 3?months after stroke.Results
In the acute phase, we found a sleep stage-dependent preferred interhemispheric asymmetry: during non-REM sleep the information flow was predominantly directed from the contralesional toward the ipsilesional hemisphere. This effect was greatly reduced in a follow-up recording 3?months after stroke onset.Conclusion
Our findings are consistent with functional imaging studies showing a transient hyperactivity of contralesional areas after stroke. We conclude that STE is a robust method for detecting post-stroke connectivity reorganizations, and that sleep stages have to be taken into account when assessing functional connectivity.Significance
EEG is more widely available than functional MRI. Future studies will have to confirm whether EEG derived STE can be useful in a clinical setting during rehabilitation after stroke. 相似文献82.

Introduction: Multiple microRNAs (miRNAs) participate in the response to hypoxic/ischemic and ischemia-reperfusion events. However, the expression of these miRNAs in circulation from patients with acute ischemic stroke (AIS) receiving recanalization treatment has not been examined, and whether they are associated with the severity and outcome of stroke is still unknown. Materials and methods: In this prospective cohort study, plasma levels of miR-125b-5p, miR-15a-3p, miR-15a-5p, and miR-206 were measured at 24 hours after thrombolysis with or without endovascular treatment in 94 patients with AIS, as determined by qRT-PCR. Stroke severity was assessed based on National Institutes of Health Stroke Scale (NIHSS) score and infarct lesion. Intracranial haemorrhage (ICH) was recorded. An unfavorable outcome was defined as a modified Rankin Scale score greater than 2 at day 90 after stroke. Results: miR-125b-5p and miR-206 levels were correlated with NIHSS scores (P = .014 and P = .002) and cerebral infarction volumes (P = .025 and P = .030). miR-125b-5p levels were significantly higher in patients with an unfavorable outcome than in patients with a favorable outcome (P = .002) and showed good diagnostic accuracy in discriminating the presence of an unfavorable outcome (area under the curve .735, 95% confidence interval .623-.829, P < .001). No association was found between different miRNAs and ICH. Conclusions: In AIS patients after thrombolysis with or without endovascular treatment, miR-125b-5p is a novel prognostic biomarker highly associated with an unfavorable outcome. miR-125b-5p and miR-206 levels are associated with stroke severity. 相似文献

目的探讨肢体缺血后处理治疗急性脑梗死的临床疗效。方法选择2015年3月~2016年6月在我院住院治疗的158例未进行溶栓治疗的急性脑梗死(发病72 h内)患者作为研究对象,所有患者均经影像证实,按照入院先后顺序随机分为治疗组和对照组。所有患者均给予常规治疗,治疗组在常规治疗的基础上给予4个短周期单侧上肢缺血再灌注,每天进行1次连续7 d。比较入院时和病程14 d时两组患者的临床疗效;入院时、病程14 d和病程3 m时的美国国立卫生研究院卒中量表(NIHSS)和磁共振灌注加权成像(PWI);入院时和病程3 m时的改良Rankin量表(mRS)、梗死体积。结果治疗14 d后,治疗组总有效率(95.9%)高于对照组(79.0%),差异有统计学意义(P0.05);两组患者NIHSS评分、rMTT在入院时和病程14 d时差异无统计学意义,均在病程3 m时差异有统计学意义(P0.05);病程3 m时,治疗组mRS较对照组下降(P0.05),治疗组梗死体积较对照组减小(P0.05)。结论在急性脑梗死患者常规治疗的基础上给予短暂性肢体缺血后处理治疗,可以提高患者的临床疗效,减轻NIHSS评分及mRS评分,减小梗死体积,增加脑灌注。 相似文献

BackgroundKnowledge available about the relationship between obstructive sleep apnea (OSA) and cognitive impairment after stroke is limited. The evolution of OSA and cognitive performance after stroke is not sufficiently described.MethodsWe prospectively enrolled and examined acute stroke patients without previously diagnosed OSA. The following information was collected: (1) demographics, (2) sleep cardio-respiratory polygraphy (PG) at 72 h, day seven, month three, and month 12 after stroke, (3) post-stroke functional disability tests at entry and at months three and 12, and (4) cognition (attention and orientation, memory, verbal fluency, language, and visual-spatial abilities) using the revised Addenbrooke's Cognitive Examination (ACE-R) at months three and 12.ResultsOf 68 patients completing the study, OSA was diagnosed in 42 (61.8%) patients. The mean apnea/hypopnea index (AHI) at study entry of 21.0 ± 13.7 spontaneously declined to 11.6 ± 11.2 at month 12 in the OSA group (p < 0.0005). The total ACE-R score was significantly reduced at months three (p = 0.005) and 12 (p = 0.004) in the OSA group. Poorer performance on the subtests of memory at months 3 (p = 0.039) and 12 (p = 0.040) and verbal fluency at months 3 (p < 0.005) and 12 (p < 0.005) were observed in the OSA group compared to non-OSA group. Visual-spatial abilities in both the OSA (p = 0.001) and non-OSA (p = 0.046) groups and the total ACE-R score in the OSA (p = 0.005) and non-OSA (p = 0.002) groups improved.ConclusionsA high prevalence of OSA and cognitive decline were present in patients after an acute stroke. Spontaneous improvements in both OSA and cognitive impairment were observed. 相似文献
