卒中后认知障碍（Post-stroke cognitive impairment，PSCI）是卒中后的主要并发症之一，是指因卒中引起 的由轻度认知功能障碍至痴呆程度的各种综合征。科学研究表明，PSCI是可逆的，通过检测患者PSCI相关 生物标志物可早期预测及发现PSCI并进行干预，文章中总结了近年来对PSCI潜在生物标志物的研究进展。

t Post-stroke cognitive impairment (PSCI) is a main complication after stroke and it refers to various degrees of syndromes from mild cognitive impairment to dementia resulting from stroke. Research show that PSCI is reversible, and detection of PSCI related biomarkers in patients can provide early prediction, detection, and intervention. In this paper, the research progress of PSCI potential biomarkers in recent years was summarized.
