For 30 years the Royal Air Force has used the EEG as part of the medical screening of candidates for aircrew training. A total of 13,658 males aged 17-25 years have been examined. None had a previous history of significant illness. Sixty-nine (0.5%) of these showed unequivocal epileptiform discharges, 44 (58%) occurring only on photic stimulation. Those with EEG discharges of uncertain significance such as 6 and 14 Hz positive spikes, 6 Hz spike and wave, and non-specific paroxysmal activity were not included. A group of 43 with a follow-up period of 5-29 years have been reviewed. Only one person developed unequivocal epilepsy. If this rate is combined with results from similar studies, the chance of healthy individuals with EEG abnormalities of this type subsequently developing epilepsy is 2-3%.
30年来，皇家空军一直将脑电图（EEG）作为飞行人员训练候选人医学筛查的一部分。总共检查了13658名年龄在17至25岁之间的男性。他们均无重大疾病史。其中69人（0.5%）显示出明确的癫痫样放电，44人（58%）仅在光刺激时出现。脑电图放电意义不明确的情况，如6赫兹和14赫兹正尖波、6赫兹尖波和慢波以及非特异性阵发性活动未被纳入。对一组43人进行了为期5至29年的随访。只有一人患上了明确的癫痫。如果将这一比率与类似研究的结果相结合，这种脑电图异常的健康个体随后患癫痫的几率为2%至3%。
