The relation between hemispheric lateralisation of intracerebral lesion and duration of impaired consciousness was investigated in 43 survivors of severe closed head injury. Duration of impaired consciousness, defined as the time from injury until the obeying of commands, was significantly longer in patients with left hemisphere than right hemisphere lesions. However, the side of intracerebral lesion had no effect on duration of impaired consciousness defined as time from injury until localisation to pain. Use of verbal methods to assess level of consciousness may be responsible for the observation that lesions of the language dominant hemisphere produce greater disturbance of consciousness than similar insults to the right hemisphere.
对43名重度闭合性颅脑损伤幸存者的脑内损伤半球侧化与意识障碍持续时间之间的关系进行了研究。意识障碍持续时间定义为从受伤到能听从指令的时间,左半球损伤患者的意识障碍持续时间明显长于右半球损伤患者。然而,脑内损伤的部位对意识障碍持续时间(定义为从受伤到对疼痛定位的时间)并无影响。使用语言方法评估意识水平可能是导致观察到语言优势半球损伤比右半球类似损伤产生更大意识障碍的原因。
