摘要
研究30名地克病流行区“健康人”的多型式脑诱发电位发现:BAEPs的Ⅰ波峰潜时,SSEPs的W值及VEPs的Ⅴ波峰潜时均较非病区同龄健康人明显延长。说明地克病流行区“健康人”虽无明显的神经精神障碍,但其脑诱发电位检查已有明显的异常,其异常机制与临床型克汀病病人只有量的差异,而无质的区别。表明环境碘缺乏是一群体性疾病。
Multimodality evoked potentials were recorded in 30 persons from the low iodine endemic area in whom no any neurological and psychological signs were found by thorough examination. The wave I of BAEPs,W of SSEPs and wave V of VEPs were found to be prolonged in variety as comparing with the control group chosen from non-endemic area .The Ⅰ- Ⅲ、 Ⅲ-VandⅠ-Ⅴ conduction time of BAEPs and the peripheral nervous conducting velocity (N CV) , conduction time between N20—N9—W and synaptic transmission (T) were nornal as comparing with the control group.The authors concluded in the same area where a number of endemic cretinism were diagnosed, there may be no true 'normal' population.If passible to record the multimodality evoked potentials, there may be a lot of individuals with abnormal responses. This kind of person may be defined as a subclinical type of endemic cretinism from the neurophysiological point of view.
