Patients with left unilateral spatial neglect draw a human face more satisfactorily than other objects. The aim of the present study is to examine the features of face drawings by patients with neglect and to establish their meaning in the diagnosis of neglect.
Sixty-four right-handed patients with a right hemisphere stroke underwent the conventional test of the Behavioural Inattention Test (BIT) and showed left unilateral spatial neglect in one or more of the subtests. From the "drawing a man or woman" subtest, 64 samples of face drawing, in which both eyes were placed, were obtained. The percentage deviation of the location of the eyes in the face outline was calculated for 46 face drawings without discontinuity of the outline or severe distortion of the construction. The percentage deviation of the location of the eyes was compared among the patients with neglect, right-hemisphere damaged patients without neglect, and healthy control subjects.
The patients with neglect placed the eyes with greater leftward deviation in the face outline compared with the other two groups. The percentage deviation of the eyes was, however, not associated with neglect severity scored with the BIT conventional test. Forty-three percent of the patients with neglect located the eyes leftward beyond the normal range obtained from the performance of the healthy subjects, while none of the patients without neglect showed such abnormal leftward deviation.
The leftward deviation of the eyes in the face drawing suggests the presence but not the severity of left unilateral spatial neglect.
单侧空间忽略症患者画人脸比其他物体更令人满意。本研究旨在检查忽略症患者的面部绘画特征，并确定其在忽略症诊断中的意义。
64 名右利手的右侧大脑半球卒中患者接受了行为忽略测试（BIT）的常规测试，并在一个或多个子测试中表现出左侧单侧空间忽略。从“画男人或女人”子测试中，获得了 64 个有眼睛的人脸样本。对于 46 个没有轮廓不连续或结构严重变形的人脸画，计算眼睛在人脸轮廓中的位置的百分比偏差。比较忽略症患者、无忽略症的右脑损伤患者和健康对照组患者的眼睛位置百分比偏差。
忽略症患者的眼睛在人脸轮廓中向左偏离的程度大于其他两组。然而，眼睛的位置偏差与 BIT 常规测试评分的忽略严重程度无关。43%的忽略症患者将眼睛定位在超出健康受试者表现的正常范围的左侧，而没有忽略症的患者则没有表现出这种异常的左侧偏差。
面部绘画中眼睛的左偏提示存在但不是单侧空间忽略的严重程度。
