摘要: <正> 問題 “智力发育不全”或“精神发育不全”一詞,来自希腊文Oligo(微少)与Phrenos(智慧)。智力发育不全儿童,在教育学与缺陷学中常被叫做“智力落后儿童”。正象吉布生(R.Gibson,1959)所指出的一样。关于智力发育不全的定义目前还有頗多不同意見,至于智力发育不全的病因、发病机制、分类与診断則尤其缺乏一致的見解[彼夫湼尔(M.C.

Abstract: EEG tracings of 106 mentally defective patients at various age levels were analyzed. Records were obtained in bipolar fashion on an "Ediswan" 16-channal EEG. "Evoked" potentials were initiated by "threshold" single and repititive flashes of light:1. Different degrees of alpha rhythm were observed for 59 out of 106 patients (55.7%), but the alpha frequency is lower than that of normals at the same age level.2. It has been suggested that theta rhythm is a common finding among mental defectives. Our results show that it seldom to display complete theta rhythm from occipital region above age 9, from temporal region above age 11 and from parietal region above age 13. The most commonly observed EEG abnormality consists of a(θ) or θ(α) patterns.3. Low percentage and short duration of "blocking" responses, occasional display and narrow range of "driving" frequency as well as absence of after-dischange are traits of the "threshold" evoked potentials in mentally defective patients.4. The incidence of EEG abnormality is highest in cases of idiots and imbeciles.
