目的：关于左脑损伤后右侧忽视的研究相对较少。作者试图使用在右半球卒中后的大型对照组中验证的综合测试组合来评估亚急性左半球卒中患者的对侧忽视。方法：对78例左半球卒中患者进行评估。测试组合包括病感失认症和视觉消退的初步评估，注视方向和个人忽视的临床评估，以及在个人周围空间的空间忽视的纸笔测试。只使用了非语言测试。结果：10%至13%的患者在绘画和取消任务中表现出忽视。组合电池比任何单独的测试更敏感。共有43.5%的患者在至少一项措施上表现出一定程度的忽视。解剖学分析表明，当后联合皮层受损时，忽视更常见和严重。结论：正如预期的那样，右侧忽视的发生频率远低于在右脑损伤中风患者中使用相同评估组合的研究中报告的频率。然而，忽视被发现在相当大比例的患者在亚急性期，这表明它应该被考虑在左脑损伤中风患者的康复计划。
Objectives: Comparatively little research has been conducted on right neglect after left brain damage. The authors sought to assess contralateral neglect in subacute left hemisphere stroke patients using a comprehensive test battery validated in a large control group after right hemisphere stroke. Methods: Seventy-eight left hemisphere stroke patients were assessed. The test battery included a preliminary assessment of anosognosia and visual extinction, a clinical assessment of gaze orientation and personal neglect, and paper-and-pencil tests of spatial neglect in the peripersonal space. Only nonverbal tests were used. Results: Drawing and cancellation tasks revealed neglect in 10 to 13% of patients. The combined battery was more sensitive than any single test alone. A total of 43.5% of patients showed some degree of neglect on at least one measure. Anatomic analyses showed that neglect was more common and severe when the posterior association cortex was damaged. Conclusions: The frequency of occurrence of right neglect was, as expected, much lower than that reported in a study using the same assessment battery in right brain damage stroke patients. Nevertheless, neglect was found in a substantial proportion of patients at a subacute stage, suggesting that it should be considered in the rehabilitation planning of left brain damage stroke patients.
