PURPOSE
We wished to determine the incidence of psychogenic nonepileptic (NES) seizures in a population-based study.
METHODS
Cases were identified through review of the results of all long-term video-EEG studies made in Iceland during the study period.
RESULTS
The incidence of NES was 1.4 in 100,000 person-years of observation. Age-specific incidence was highest in the youngest age group (age 15-24 years) and decreased thereafter. A strong female preponderance was observed.
CONCLUSIONS
The incidence of NES is equal to almost 4% of that reported for epilepsy from Iceland for persons aged > or = 15 years. For people aged 15-24 years, the incidence of NES is equal to approximately 5% of the incidence of epilepsy. Half the patients also had epilepsy.
目的
我们希望在一项基于人群的研究中确定心因性非癫痫性发作（NES）的发病率。
方法
通过回顾研究期间在冰岛进行的所有长期视频脑电图研究结果来确定病例。
结果
在100,000人年的观察中，NES的发病率为1.4。特定年龄发病率在最年轻年龄组（15 - 24岁）最高，之后下降。观察到女性占比很大。
结论
对于年龄≥15岁的人群，NES的发病率几乎等于冰岛报告的癫痫发病率的4%。对于15 - 24岁的人群，NES的发病率约等于癫痫发病率的5%。一半的患者同时患有癫痫。
