Stroke could lead to deficits in organization of visual search. Cancellation tests are frequently used in standard neuropsychological assessment and appear suitable to measure search organization. The current aim was to evaluate which cognitive functions are associated with cancellation organization measures after stroke.
Stroke patients admitted to inpatient rehabilitation were included in this retrospective study. We performed exploratory factor analyses to explore cognitive domains. A digital shape cancellation test (SC) was administered, and measures of search organization (intersections rate and best r) were computed. The following cognitive functions were measured by neuropsychological testing: neglect (SC, line bisection; LB, Catherine Bergego Scale; CBS, and Balloons Test), visuospatial perception and construction (Rey Complex Figure Test, RCFT), psychomotor speed (Trail Making Test; TMT-A), executive functioning/working memory (TMT-B), spatial planning (Tower Test), rule learning (Brixton Test), short-term auditory memory (Digit Span Forward; DSF), and verbal working memory (Digit Span Backward; DSB).
In total, 439 stroke patients were included in our analyses. Four clusters were separated: "Executive functioning" (TMT-A, TMT-B, Brixton Test, and Tower Test), "Verbal memory" (DSF and DSB), "Search organization" (intersections rate and best r), and "Neglect" (CBS, RCFT copy, Balloons Test, SC, and LB).
Search organization during cancellation, as measured with intersections rate and best r, seems a distinct cognitive construct compared to existing cognitive domains that are tested during neuropsychological assessment. Administering cancellation tests and analyzing measures of search organization could provide useful additional insights into the visuospatial processes of stroke patients. (JINS, 2018, 24, 424-436).
中风可能导致视觉搜索组织受损。消去测验常用于标准神经心理学评估，似乎适合测量搜索组织。本研究旨在评估中风后哪些认知功能与消去测验的搜索组织测量结果相关。
本回顾性研究纳入了住院康复的中风患者。我们进行了探索性因素分析以探索认知领域。进行了数字形状消去测验（SC），并计算了搜索组织的测量指标（交点率和最佳 r）。通过神经心理学测试测量了以下认知功能：忽视（SC、线二分法；LB、Catherine Bergego 量表；CBS、气球测试）、视空间感知和构建（Rey 复杂图形测试，RCFT）、运动速度（连线测验 A；TMT-A）、执行功能/工作记忆（TMT-B）、空间规划（Tower 测验）、规则学习（Brixton 测验）、短期听觉记忆（数字广度正向；DSF）和言语工作记忆（数字广度逆向；DSB）。
共有 439 例中风患者纳入本研究分析。分离出四个聚类：“执行功能”（TMT-A、TMT-B、Brixton 测验和 Tower 测验）、“言语记忆”（DSF 和 DSB）、“搜索组织”（交点率和最佳 r）和“忽视”（CBS、RCFT 复制、气球测试、SC 和 LB）。
与神经心理学评估中测试的现有认知领域相比，消去测验中的搜索组织（交点率和最佳 r）似乎是一个独特的认知结构。进行消去测验并分析搜索组织的测量指标，可以为中风患者的视空间过程提供有用的额外见解。（JINS，2018，24，424-436）。
