We evaluated drawing disability in 37 patients with right hemispheric stroke and in eight controls with no brain disease. Blinded evaluations included measures of overall recognizability and hemineglect. By mapping the CT lesions of patients, we found that damage to parieto-occipital cortex in poor drawers correlated with poor performance on a line bisection task whereas frontal, subcortical damage in poor drawers did not. We propose that drawing disability may be produced by visual-spatial dysfunction in patients with posterior lesions and by a disturbance of integrated motor function in those with frontal, subcortical damage.
我们评估了37例右半球卒中患者和8例无脑部疾病的对照者的绘图障碍。盲法评估包括整体可识别性和半侧忽视的测量。通过绘制患者的CT病变图，我们发现绘图能力差的患者顶枕叶皮质损伤与直线二等分任务表现不佳相关，而绘图能力差的患者额叶、皮质下损伤则不然。我们提出，绘图障碍可能是由后部病变患者的视觉空间功能障碍以及额叶、皮质下损伤患者的综合运动功能紊乱所致。
