【摘要】 采用睡眠部分剥夺方法进行脑电图（ＥＥＧ）睡眠描记。通过观察ＥＥＧ背景活动和对刺激（声响、感觉）的反应来排除睡眠纺锤波假性缺失，发现５６例中枢神经系统疾病患儿睡眠纺锤波缺失。结果表明：该波缺失常与急、慢性脑损伤，尤其急性脑病变有关，本组急性脑疾患占７８．６％。提示单侧或灶性缺失者常存在脑内局灶性病变。该波的恢复对判断颅脑疾病转归有一定意义。更多还原

【Abstract】 AbstractEEG during sleep was recorded by the method ofpartial sleep deprivation. False absence of sleep spin-dle in EEGs was excluded by observation on change ofbackground activity in EEGs and behaviour responseto stimulation tsound and sense). Our results showedthe absence of sleep spindle in 56 cases of cerebral dis-eases, especially in acute brain damage (ABD). whichaccounted for 78.6% of the patients in this study. Aunilateral or focal absence of spindle suggested thepossibility of a focal lesion in the brain. The recoveryof spindle was of some value in judgement of outcomeof eerebral disorders. The diagnostic criteria of ab-sence of sleep spindle included: (1) age more than 3months, (2) persistent absenee of spindle during the re-cording time of more than 15 minutes light sleep ofNREM or more than 10 minutes after vertex wavesappeared.更多还原
