Although several studies have reported on the risk of "early seizures" (seizures occurring within 7 days following a head injury), the reported proportions of patients experiencing these seizures vary from 1.4 to 15%. This wide divergence may be due to problems with methodology such as case selection and definitions of head injury and early seizures. In a series of 702 patients admitted with a head injury to Cook County Hospital (CCH), Chicago, Illinois, 29 (4.1%) had early seizures. This proportion is twice as high as one previously reported in a comparable series. This may reflect an actual difference between the two series or a case selection bias serving to elevate the proportion of patients with early seizures at CCH.
尽管有多项研究报告了“早期癫痫发作”（头部受伤后7天内发生的癫痫发作）的风险，但报告的经历这些癫痫发作的患者比例从1.4%到15%不等。这种巨大差异可能是由于诸如病例选择以及头部损伤和早期癫痫发作的定义等方法学问题所致。在伊利诺伊州芝加哥市库克县医院（CCH）收治的702例头部受伤患者中，有29例（4.1%）发生了早期癫痫发作。这一比例是之前在类似病例系列中报告的比例的两倍。这可能反映了两个系列之间的实际差异，或者是一种病例选择偏倚，导致CCH早期癫痫发作患者的比例升高。
