Abstract

From a sample of 90 stroke cases showing visual inattention following right hemisphere brain damage, 17 cases were identified who showed more inattention on the right than the left side on some tests. Eight of these subjects had CT scan-confirmed unilateral right hemisphere damage and one of these eight had MRI scan-confirmed unilateral right brain damage. A number of hypotheses are examined to explain this "paradoxical" right inattention. The most parsimonious proposes that right inattention is produced by an interaction of a compensatory left sided scanning strategy in association with a non-lateralised attentional loss.

摘要

在一个由90例右半球脑损伤后出现视觉注意力不集中的中风病例组成的样本中，有17例在某些测试中表现出右侧比左侧更明显的注意力不集中。其中8名受试者经CT扫描证实为单侧右半球损伤，这8人中的1人经MRI扫描证实为单侧右脑损伤。本文研究了多种假设来解释这种“矛盾的”右侧注意力不集中现象。最简洁的假设认为，右侧注意力不集中是由代偿性左侧扫描策略与非偏侧化注意力丧失相互作用产生的。
