关于轻度头部受伤后认知缺陷和脑震荡后症状 (PCS) 的性质和持续时间存在很多争论。 迄今为止进行的大多数研究都是将头部受伤的患者与未遭受脑震荡的受试者进行比较，而不是直接比较患有和不患有持续性 PCS 的患者。 本研究检验了在无并发症的轻度头部损伤后约 6 个月患有 PCS 的患者 (n = 9) 在选定的神经心理学测试中的表现是否低于未患有 PCS 的轻度头部损伤患者 (n = 9) 和健康对照 (n = 9)。 PCS 患者与对照组在受伤后的时间、年龄、性别和教育程度方面进行了单独匹配。 我们发现，与没有 PCS 的患者和健康对照相比，PCS 患者在分散注意力和选择性注意力测试中的表现较差。 结论是，当症状持续存在时，认知缺陷可能会在轻度头部受伤后 6 个月内出现。 研究结果表明，轻度头部损伤和主观症状的患者可能表现出明显的认知缺陷。
There is much debate on the nature and duration of cognitive deficits and postconcussive symptoms (PCS) after mild head injury. Most studies performed so far have compared head-injured patients with subjects who had not suffered a concussion, instead of directly comparing patients with and without persistent PCS. The present study examined whether patients with PCS (n = 9) about 6 months after an uncomplicated mild head injury performed less well on selected neuropsychological tests than patients with mild head injuries who did not have PCS (n = 9) and healthy controls (n = 9). Patients with PCS were individually matched with controls for the time elapsed after the injury, age, sex, and education. We found that patients with PCS performed less well on tests of divided and selective attention than both patients without PCS and healthy controls. It is concluded that cognitive deficits may be present up to 6 months after mild head injury when symptoms persist. The findings indicate that patients with mild head injury and subjective symptoms may manifest demonstrable cognitive deficits.
