Post-concussional symptoms, such as headache, dizziness and irritability, are thought to result from the emotional stress associated with decreased cognitive performance after a head injury. A questionnaire-based investigation was carried out in 71 patients with mild head injury (MHI), using a heterogeneous item pool in order to study the interrelationships between traditional post-concussive complaints, cognitive problems, and more emotional and functional complaints. Factor analysis indicated that post-concussive symptoms loaded together with items on problems associated with decreased work performance and fatigability on a first factor, whereas psychovegetative and emotional complaints loaded together on a second factor. Two rating scales were constructed from the relevant items and were used to compare between subgroups of MHI patients and non-concussed controls. Patients with uncomplicated MHI had significantly higher scores than non-concussed subjects on the post-concussive-cognitive scale, but not on the emotional-vegetative scale. Patients with multiple head injuries or pre-existing emotional problems had higher scores on both the post-concussive-cognitive scale and the emotional-vegetative scale than MHI patients without a history of emotional problems. Reliable rating scales may be useful in multidiagnostic studies of MHI patients.
脑震荡后症状，如头痛、头晕和易怒，被认为是由头部受伤后认知能力下降相关的情绪压力所致。对71例轻度头部损伤（MHI）患者进行了一项基于问卷的调查，使用了一个异质性项目库，以研究传统脑震荡后症状、认知问题以及更多情绪和功能症状之间的相互关系。因子分析表明，脑震荡后症状与工作表现下降和易疲劳相关问题的项目共同加载在第一个因子上，而精神植物神经和情绪症状共同加载在第二个因子上。从相关项目构建了两个评定量表，并用于比较MHI患者亚组和未发生脑震荡的对照组。单纯性MHI患者在脑震荡后认知量表上的得分显著高于未发生脑震荡的受试者，但在情绪植物神经量表上则不然。有多次头部损伤或既往有情绪问题的患者在脑震荡后认知量表和情绪植物神经量表上的得分均高于无情绪问题病史的MHI患者。可靠的评定量表可能有助于对MHI患者进行多诊断研究。
