Quantitative assessment of brain damage is a primary condition for studies in neurotraumatology. Scored clinical evaluation, neurophysiological and neuroimaging techniques are usefully applied in highly disabled or comatose patients. In minor head injury (MHI), where focal neurological signs are excluded by definition, quantification of brain dysfunction is still uncertain. We compared the incidence of post-traumatic amnesia (PTA), skull fractures and altered Auditory Brainstem Responses (ABR) in 165 patients examined within 48 hours from a MHI. Skull fractures were found in 25%. They are, however, an indirect evidence of potential cerebral damage. ABR alterations, which show brainstem dysfunction, were present in 10% only. PTA exceeding 30 min occurred in 60% of MHI patients. This clinical method seems a sensitive method for assessing brain dysfunction even in MHI patients.
脑损伤的定量评估是神经创伤学研究的首要条件。评分临床评估、神经生理学和神经影像学技术有效地应用于重度残疾或昏迷患者。在轻度头部损伤（MHI）中，根据定义排除了局灶性神经体征，脑功能障碍的量化仍不确定。我们比较了165例在MHI后48小时内接受检查的患者中创伤后遗忘（PTA）、颅骨骨折和听觉脑干反应（ABR）改变的发生率。25%的患者发现有颅骨骨折。然而，它们是潜在脑损伤的间接证据。显示脑干功能障碍的ABR改变仅出现在10%的患者中。60%的MHI患者出现PTA超过30分钟。这种临床方法似乎是评估MHI患者脑功能障碍的一种敏感方法。
