The frequency of various types of unilateral spatial neglect and associated areas of neural dysfunction after left hemisphere stroke are not well characterized. Unilateral spatial neglect (USN) in distinct spatial reference frames have been identified after acute right, but not left hemisphere stroke. We studied 47 consecutive right handed patients within 48h of left hemisphere stroke to determine the frequency and distribution of types of right USN using cognitive testing and MRI imaging. The distribution of USN types was different from the previously reported distribution following acute right hemisphere stroke. In this left hemisphere stroke population, allocentric neglect was more frequent than egocentric neglect.
左半球中风后各种类型的单侧空间忽视及相关神经功能障碍区域的频率尚未得到很好的描述。在急性右半球而非左半球中风后,已在不同的空间参照系中识别出单侧空间忽视(USN)。我们研究了47例连续的左半球中风后48小时内的右利手患者,通过认知测试和MRI成像来确定右侧USN类型的频率和分布。USN类型的分布与先前报道的急性右半球中风后的分布不同。在这个左半球中风人群中,allocentric忽视比egocentric忽视更常见。
