Post-stroke depression (PSD) and post-stroke cognitive impairment (PSCI) are common complications following a stroke, significantly impacting the quality of life and survival time of survivors. Currently, the comorbidity of PSCI and PSD is receiving increasing attention, as they share some common clinical characteristics, mechanisms, risk factors, radiological features, and treatment strategies. They influence each other, with the clinical prevalence of PSD comorbid with PSCI reaching as high as 26.15 %. The prevention, screening, diagnosis, and treatment of PSD and PSCI require collaboration across clinical, radiological, and neuropsychological evaluations. This paper aims to summarize the common radiological features of both conditions from a radiological perspective, which may aid in identifying early screening and predictive imaging biomarkers.

脑卒中后抑郁及认知障碍患者影像学特征分析

中风后抑郁（PSD）和中风后认知障碍（PSCI）是中风后常见的并发症，显着影响幸存者的生活质量和生存时间。目前，PSCI和PSD的合并症越来越受到关注，因为它们具有一些共同的临床特征、机制、危险因素、影像学特征和治疗策略。它们相互影响，PSD合并PSCI的临床患病率高达26.15%。PSD 和 PSCI 的预防、筛查、诊断和治疗需要临床、放射学和神经心理学评估方面的合作。本文旨在从放射学角度总结这两种疾病的共同放射学特征，这可能有助于识别早期筛查和预测成像生物标志物。
