Association Between Fatigue and Cognitive Impairment at 6 Months in Patients With Ischemic Stroke Treated With Acute Revascularization Therapy.

ABSTRACT: Background: Fatigue is a frequent symptom after stroke. We aimed to determine the association between fatigue and cognitive performance in patients with ischemic stroke who received acute revascularization therapy (IV thrombolysis and/or mechanical thrombectomy). Methods: Seventy patients were prospectively included in the stroke unit of the University Hospital of Dijon, France. A follow-up was performed at 6 months with clinical examination, fatigue assessment by the Fatigue Severity Scale (FSS), and a comprehensive neuropsychological evaluation. Patients with fatigue (FSS score >4) were compared with patients without fatigue. Neuropsychological factors associated with fatigue at 6 months were analyzed using multivariable logistic regression models. Results: Fatigue was reported by 34.3% of patients. Patients with fatigue were older, had more frequent residual handicap, depressive symptoms, and impaired quality of life. They had more frequently low score (<26) on the MoCA scale (79.2 vs. 47.8%, OR = 4.15; 95% CI: 1.32-13, p = 0.015), memory impairment (60 vs. 30.6%, OR = 3.41; 95% CI: 1.09-10.7, p = 0.035), and executive dysfunction (65 vs. 30.8%, OR = 4.18; 95% CI: 1.33-13.1, p = 0.014). In multivariable logistic regression analysis, only memory impairment was independently associated with fatigue (OR = 5.70; 95% CI: 1.09-29.6, p = 0.039). Further analyses restricted to non-depressed patients (n = 58, 84.1%) showed in multivariable models that a score < 26 on MoCA scale (OR 5.12; 95% CI: 1.00-26.2, p = 0.05), and a memory impairment (OR = 6.17; 95% CI: 1.06-35.9, p = 0.043) were associated with fatigue. There was also a non-significant trend toward an association between divided attention deficit and fatigue (OR = 6.79; 95% CI: 0.80-57.6, p = 0.079). Conclusion: The association between fatigue and subtle cognitive impairment including memory or attention deficits could be of interest in elaborating future interventional studies to evaluate the impact of therapeutic strategies, including cognitive rehabilitation, on fatigue.

Project description:IntroductionIntravenous thrombolysis (IVT) and mechanical thrombectomy (MT) in women with ischemic stroke (IS) during pregnancy/post-partum is challenging, and recent guidelines claimed for additional information to better argue its effectiveness and safety. This observational national study aimed to describe characteristics, rates and outcomes of pregnant/post-partum women receiving acute revascularization therapy for IS compared to their non-pregnant counterparts, and pregnant women with IS not receiving such therapy.Patients and methodsIn this cross-sectional study, all women aged 15-49 years hospitalized in France for IS between 2012 and 2018 were retrieved from the French hospital discharge databases. Pregnant or post-partum (⩽6 weeks after delivery) women were identified. Data about patients' characteristics, risk factors, revascularization therapy, delivery, post-stroke survival, and recurrent vascular events during follow-up were recorded.ResultsOver the study period, 382 women with pregnancy-related IS were registered. Among them, 7.3% (n = 28) received a revascularization therapy, including nine cases during pregnancy, one the same day as delivery, and 18 during the post-partum period, compared with 8.5% (n = 1285) in women with non-pregnancy-related IS (n = 15,084). Treated pregnant/post-partum women had more severe IS than not-treated pregnant/post-partum. Compared with treated not-pregnant women, they were younger, but did not differ regarding other characteristics including stroke severity. There were no differences in systemic or intracranial hemorrhages or in the length of hospital stay between pregnant/post-partum women compared with treated not-pregnant women. All women receiving revascularization during pregnancy had a live baby. After a mean follow-up of 4.3 years, all pregnant/post-partum women were alive, one had recurrent IS and none had other vascular events.Discussion and conclusionOnly a few women with pregnancy-related IS were treated with acute revascularization therapy, but this was proportionately similar to their non-pregnant counterparts, from whom they did not differed regarding characteristics, survival, and risk of recurrent events. These findings suggest that stroke physicians applied treatment strategies of IS in a similar way regardless of pregnancy in France, and this attitude was an anticipation but consistent with the recently published guidelines on the topic.

Project description:Background and Aims: Systemic inflammation is associated with an increased risk of cognitive impairment and dementia, but the associations between them in stroke patients are less clear. We examined the impact of systemic inflammation represented as the neutrophil-lymphocyte ratio (NLR) on the development of post-stroke cognitive impairment (PSCI) and domain-specific cognitive outcomes 3-month after ischemic stroke. Methods: Using prospective stroke registry data, we consecutively enrolled 345 participants with ischemic stroke whose cognitive functions were evaluated 3-month after stroke. Their cognition was assessed with the Korean version of the Vascular Cognitive Impairment Harmonization Standards and the Korean-Mini Mental Status Examination. PSCI was defined as a z-score of < -2 standard deviations for age, sex, and education adjusted means in at least one cognitive domain. The participants were categorized into five groups according to the quintiles of NLR (lowest NLR, Q1). The cross-sectional association between NLR and PSCI was assessed using multiple logistic regression, adjusting for age, sex, education, vascular risk factors, and stroke type. Results: A total of 345 patients were enrolled. The mean age was 63.0 years and the median NIHSS score and NLR were 2 [1-4] and 2.26 [1.65-2.91], respectively. PSCI was identified in 71 (20.6%) patients. NLR was a significant predictor for PSCI both as a continuous variable (adjusted OR, 1.14; 95% CI, 1.00-1.31) and as a categorical variable (Q5, adjusted OR, 3.26; 95% CI, 1.17-9.08). Patients in the Q5 group (NLR ≥ 3.80) showed significantly worse performance in global cognition and in visuospatial and memory domains. Conclusions: NLR in the acute stage of ischemic stroke was independently associated with PSCI at 3 months after stroke, and high NLR was specifically associated with cognitive dysfunction in the memory and visuospatial domains. Thus, systemic inflammation may be a modifiable risk factor that may influence cognitive outcomes after stroke.
