摘要

儿童中风后认知功能障碍的患病率很高，各种危险因素影响长期认知预后。风险因素是否以及如何与认知结果相关联仍不完全清楚。本研究调查了儿童中风后出院时、6个月和2年的病变体积、病变位置和神经功能对长期认知预后的影响。这项观察性研究包括儿童动脉缺血性卒中后的患者。卒中后至少一年评估长期认知结果（智力、处理速度、工作记忆）（Md = 3.52, IQR = 5.57）。在出院时、6个月和2年随访时使用小儿卒中结局测量法测量神经功能。应用脑卒中表现时的磁共振成像分析急性到亚急性病变指标(体积&；位置)。43例6 ~ 23岁患者（Md = 6.17, IQR = 7.58）入组研究。认知功能与病变体积（处理速度：r =−）显著相关。423, p = 0.005；工作记忆：r =−。478, p = .002)。当左尾状核受累时，工作记忆较差(U = 284.5, p <；.001, d = 1.43)。长期认知结果与出院、6个月和2年随访时的神经功能相关，尽管影响因所测量的认知领域而异(出院：r = .449, p = .003；6个月;R = .509 ~ .538, p <；2年随访：r = .588 ~ .744, p <.001)。长期认知结果与病变体积、病变位置和神经功能有关。我们的研究增加了长期认知康复的危险因素的确定，并强调了对神经和认知结果进行综合评估的必要性。

Impact of lesion metrics and neurological functions on long-term cognitive outcome in childhood stroke

The prevalence of cognitive impairment after childhood stroke is high and various risk factors influence long-term cognitive outcome. Whether and how risk factors are associated with cognitive outcome is still incompletely understood. This study investigated how lesion volume, lesion location and neurological functions at discharge, 6 months and 2 years after childhood stroke contribute to long-term cognitive outcome.

This observational study included patients after childhood arterial ischemic stroke. Long-term cognitive outcome (intelligence, processing speed, working memory) was assessed at least one year after stroke (Md = 3.52, IQR = 5.57). Neurological functions were measured using the pediatric stroke outcome measure at discharge, at 6-month and 2-year follow-up. Magnetic resonance imaging at stroke manifestation was applied to analyze acute to subacute lesion metrics (volume & location).

43 patients aged 6–23 years (Md = 6.17, IQR = 7.58) were enrolled in the study. Cognitive functions significantly correlated with lesion volume (processing speed: r = −.423, p = .005; working memory: r = −.478, p = .002). Working memory was worse if the left caudate nucleus was involved (U = 284.5, p < .001, d = 1.43). Long-term cognitive outcome correlated with neurological functions at discharge, 6-month and 2-year follow-up, although effects varied depending on the cognitive domain measured (discharge: r = .449, p = .003; 6-month; r = .509 to .538, p <.001; 2-year follow-up: r = .588 to .744, p <.001).

Long-term cognitive outcome was associated with lesion volume, lesion location and neurological functions. Our study adds to the determination of risk factors for long-term cognitive rehabilitation and highlights the need for the combined evaluation of neurological and cognitive outcome.
