We studied 171 consecutive patients with an acute hemispheric stroke (69 right hemisphere, 102 left), at 2-3 days post-stroke. A standardized test battery, previously validated in patients with acute stroke, was used to detect a wide variety of neglect phenomena and related disorders. Visual neglect was found in 82% of assessable right hemisphere patients and 65% of left hemisphere patients. Hemi-inattention was found in 70% of right and 49% of left hemisphere strokes. Tactile extinction was found in 65% of right and 35% of left hemisphere patients; allaesthesia in 57% (right), and 11% (left); visual extinction in 23% (right) 2% (left). Anosognosia was found in 28% (right), and 5% (left); anosodiaphoria in 27% (right), and 2% (left); non-belonging in 36% (right) and 29% (left). Visual neglect occurred more commonly in left hemisphere stroke than previously reported. Although neglect phenomena and related disorders were associated with right hemisphere damage, it is possible that language difficulties obscured their presence in some patients with a left hemisphere stroke.
我们研究了171例连续的急性半球性卒中患者（69例右侧半球卒中，102例左侧半球卒中），均为卒中后2 - 3天。使用先前在急性卒中患者中验证过的标准化测试组合来检测各种忽视现象及相关障碍。在可评估的右侧半球患者中，82%发现有视觉忽视，左侧半球患者中这一比例为65%。右侧半球卒中患者中70%发现有半侧注意力不集中，左侧半球卒中患者中这一比例为49%。右侧半球患者中65%发现有触觉消退，左侧半球患者中这一比例为35%；右侧57%、左侧11%有感觉异常；右侧23%、左侧2%有视觉消退。右侧28%、左侧5%有疾病感缺失；右侧27%、左侧2%有疾病失认；右侧36%、左侧29%有陌生感。视觉忽视在左侧半球卒中患者中比先前报道的更常见。尽管忽视现象及相关障碍与右侧半球损伤有关，但在一些左侧半球卒中患者中，语言困难可能掩盖了这些现象的存在。
