The authors present a case of transient left hemispatial inattention following traumatic brain injury in a three-year-old child. Computed tomographic scan revealed a small right frontal and a right temporo-parietal contusion. Stimuli were developed to quantify the response difference between hemifields in this pre-literate child. Hemispatial inattention showed resolution at 19 days post-trauma and had completely resolved six months later. These findings suggest that right hemisphere systems subserve visually guided attention before six years of age.
作者报告了一例三岁儿童创伤性脑损伤后出现短暂性左侧半空间忽视的病例。计算机断层扫描显示右侧额叶和右侧颞顶叶有小挫伤。针对这个未识字儿童开发了刺激方法来量化半视野之间的反应差异。半空间忽视在创伤后19天有所缓解,六个月后完全消失。这些发现表明,六岁前右半球系统负责视觉引导的注意力。
