Neglect is a disabling state in stroke patients. Five tests for visuo-spatial neglect, star cancellation, line crossing, line bisection, draw a clock and copy a cross, were compared in 57 elderly patients. Sensitivity and intercorrelations between the tests were determined. Patients with neglect were studied as regards their activities of daily living, motor activity and cognition. Left-hemisphere neglect in patients with right-hemisphere lesions was more severe than right-sided neglect in patients with left-sided lesions in the star cancellation test. Sensitivity of the tests was moderate for star cancellation, line bisection and draw a clock, and low for line crossing and copy a cross. Significant correlations existed between the tests and cognitive and functional ability. Intercorrelations between the tests were moderate. Neglect patients showed a slower recovery after 6 and 12 months. Draw a clock and a cross displayed no sensitivity for neglect in patients with hemianopia, which may be due to the fact that these tests also evaluate constructional apraxia. The cancellation tests were influenced by hemianopia and there is evidence that hemianopia exacerbates neglect. This study shows that a battery of neglect tests is required to diagnose the neglect syndrome.
忽视是中风患者的一种致残状态。对57名老年患者比较了五项视觉空间忽视测试，即星形删除、划消线、直线二等分、画钟和临摹十字。确定了测试之间的敏感性和相互关系。对忽视患者的日常生活活动、运动活动和认知进行了研究。在星形删除测试中，右半球病变患者的左侧忽视比左半球病变患者的右侧忽视更严重。星形删除、直线二等分和画钟测试的敏感性中等，划消线和临摹十字测试的敏感性较低。测试与认知和功能能力之间存在显著相关性。测试之间的相互关系中等。忽视患者在6个月和12个月后恢复较慢。对于偏盲患者，画钟和临摹十字对忽视不显示敏感性，这可能是因为这些测试也评估结构性失用症。删除测试受偏盲影响，有证据表明偏盲会加重忽视。这项研究表明，需要一系列忽视测试来诊断忽视综合征。
