The objective of the study was to determine how performance on cognitive assessments administered in the subacute phase of mild stroke change or remain stable over time. A prospective longitudinal cohort pilot study was used to assess the cognitive status of participants with mild stroke (n = 20) at two time points: (1) within 3 weeks post-discharge from the acute care setting following mild stroke, and (2) approximately 6 months post-mild stroke. Participants were given a battery of cognitive assessments at both time points that included the following measures: (1) Short Blessed Test, (2) California Verbal Learning Test (CVLT), (3) Connor's Continuous Performance Task (CPT), and (4) The Delis-Kaplan Executive Function System (DKEFS) Trail Making subtest. The only significant differences between the test administrations was on the CVLT Short Delay Free Recall (p = .027) and Long Delay Free Recall (p = .002) which was likely due to practice effects associated with this measure. The results of the study show that performance on standardised cognitive testing in the early phases of mild stroke remained stable over a 6 month period. These results help justify the necessity and ability to assess cognition immediately post-mild stroke in order to make accurate and appropriate rehabilitation recommendations.

该研究的目的是确定在轻度中风的亚急性阶段进行的认知评估的表现如何随时间变化或保持稳定。前瞻性纵向队列试验用于评估轻度卒中参与者 (n = 20) 在两个时间点的认知状况 :( 1) 轻度卒中后出院后3周内,以及 (2) 轻度卒中后约6个月。参与者在两个时间点都接受了一系列认知评估,包括以下措施 :( 1) 简短的祝福测试,(2) 加州语言学习测试 (CVLT),(3) 康纳的持续表现任务 (CPT),(4) Delis-Kaplan执行功能系统 (DKEFS) 跟踪子测试。测试管理之间的唯一显着差异是CVLT短延迟免费召回 (p =  .027) 和长延迟免费召回 (p =  .002),这可能是由于与该措施相关的实践效果。研究结果表明,在轻度中风的早期阶段,标准化认知测试的表现在6个月内保持稳定。这些结果有助于证明轻度卒中后立即评估认知的必要性和能力,以便提出准确和适当的康复建议。
