A left-handed patient suddenly developed a right hemiparesis, mirror-reading, and mirror-writing. Although he could discriminate between right and left on himself, he demonstrated right/left spatial disorientation. We propose that his right/left spatial disorientation was induced by a scanning defect. It has been demonstrated that mirror-image engrams are normally available. We believe that a reversal of the learned left-to-right scanning process with the availability of mirror engrams induced mirror-reading. Similarly, reversal of the normal left-to-right writing pattern, with the availability of mirror engrams, induced mirror-writing.
一名左利手患者突然出现右侧偏瘫、镜像阅读和镜像书写。尽管他能区分自己身体的左右侧，但仍表现出左右空间定向障碍。我们认为他的左右空间定向障碍是由扫描缺陷引起的。已经证实，镜像记忆痕迹通常是存在的。我们相信，由于镜像记忆痕迹的存在，习得的从左到右的扫描过程发生逆转，从而导致了镜像阅读。同样，由于镜像记忆痕迹的存在，正常的从左到右的书写模式发生逆转，导致了镜像书写。
