Although research focused on mild traumatic brain injury (mTBI) has proliferated in recent years, few studies have examined the significance of a previous history of mTBI in children.
To compare the acute injury presentation and neuropsychological recovery in a pediatric sample after mTBI.
Participants 8 to 16 years of age were divided into 4 groups: no previous injury history, history of 1 mTBI, history of 2 mTBIs, and history of ≥ 3 mTBIs. Participants were evaluated within 3 months of the most recent injury by clinical interview and an abbreviated neuropsychological test battery.
After the index mTBI, the groups did not differ in their likelihood to display a loss of consciousness, nor did they differ on neuropsychological test performance.
Overall, contrary to our hypotheses, we found no demonstrable difference between those children with a self-reported mTBI history and those without after an index mTBI.
尽管近年来针对轻度创伤性脑损伤（mTBI）的研究大量增加，但很少有研究探讨儿童既往mTBI病史的意义。
比较小儿mTBI样本中的急性损伤表现和神经心理恢复情况。
将8至16岁的参与者分为4组：无既往损伤史、1次mTBI病史、2次mTBI病史和≥3次mTBI病史。在最近一次损伤后的3个月内，通过临床访谈和简短的神经心理测试组对参与者进行评估。
在此次mTBI之后，各组在出现意识丧失的可能性方面没有差异，在神经心理测试表现上也没有差异。
总体而言，与我们的假设相反，我们发现自我报告有mTBI病史的儿童与此次mTBI后无该病史的儿童之间没有明显差异。
