Despite controversy surrounding the concept of mild head injury (MHI), it is becoming evident that even a head trauma termed 'mild' may result in significant behavioural sequelae. The present study was an attempt at documenting structural cerebral damage, by way of computerized tomography, in a group of patients having suffered a MHI as defined by the Glasgow Coma Scale (GCS) score. A 1-year retrospective chart review identified 80 MHI patients who presented to the Emergency department of a lead hospital for trauma. Sixty-six per cent of these MHI patients were scanned. Evidence of intracranial abnormalities was obtained in 31% of the overall sample. Patients with a lower GCS score had a higher percentage of abnormal scans than those with a GCS score of either 14 or 15. The present findings suggest that a MHI can be associated with significant morbidity, and that a MHI group does not constitute a homogeneous pool of patients.
尽管围绕轻度头部损伤（MHI）的概念存在争议，但越来越明显的是，即使是被称为“轻度”的头部创伤也可能导致显著的行为后遗症。本研究试图通过计算机断层扫描记录一组根据格拉斯哥昏迷量表（GCS）评分定义为轻度头部损伤患者的脑结构损伤情况。一项为期1年的回顾性病历审查确定了80名在一家主要创伤医院急诊科就诊的轻度头部损伤患者。这些轻度头部损伤患者中有66%接受了扫描。在整个样本中，31%的患者有颅内异常的证据。格拉斯哥昏迷量表评分较低的患者扫描异常的百分比高于格拉斯哥昏迷量表评分为14或15的患者。目前的研究结果表明，轻度头部损伤可能与显著的发病率相关，并且轻度头部损伤患者群体并非同质化的。
