The results of electroencephalographic screening of 3225 inpatients from a community general hospital psychiatric service were reviewed. When patients with a prior diagnosis of epilepsy were excluded, epileptiform abnormalities were discovered in 2.6% of patients. Patients younger than age 25 years and patients with a diagnostic impression of anorexia nervosa, recent barbiturate abuse, or nonpsychotic explosive behavior were significantly more likely to have epileptiform abnormalities. The use of certain therapeutic agents was associated with a significant excess of epileptiform abnormalities in patients aged 25 years and older. The most frequently encountered epileptiform abnormalities were photoconvulsive responses. Focal temporal epileptiform abnormalities were detected in only four patients without a prior diagnosis of epilepsy. The diagnosis of epilepsy on the basis of a primarily psychiatric presentation and the discovery of epileptiform abnormalities on electroencephalographic screening should be approached with caution.
回顾了一家社区综合医院精神科3225名住院患者的脑电图筛查结果。排除先前诊断为癫痫的患者后，2.6%的患者发现有癫痫样异常。年龄小于25岁的患者以及诊断为神经性厌食症、近期有巴比妥类药物滥用或非精神病性爆发行为的患者，出现癫痫样异常的可能性显著更高。在25岁及以上的患者中，使用某些治疗药物与癫痫样异常显著增多有关。最常见的癫痫样异常是光惊厥反应。仅在4名先前未诊断为癫痫的患者中检测到局灶性颞叶癫痫样异常。对于基于主要精神症状表现诊断癫痫以及在脑电图筛查中发现癫痫样异常的情况，应谨慎对待。
