发作性头痛的脑波涨落图分析

目的 探讨发作性头痛的脑波涨落特征，为航空航天作业人员选拔提供参考方法。方法应用脑波科技术分析了２０例临床诊断为发作性头痛的患者在７￣１２ＨＺ频段皮优势频率落特征和该频段脑波的功率涨落功率谱特征。其中男性１３例，女性７例，年龄在１７￣３７岁。结果在发作期，与头痛相对应的导联，脑波７￣１２Ｈｚ频段呼频率出现优势涨落概率高低依脑波频率由慢到快依次分布，即按７、８、９、１０、１１及１２ＨＺ顺序排列。且由

A Fluctuographic Analysing of EEG in Patients with Paroxysmal Headache

Objective: To offer reference of the screening procedure for aircrew and astronaut selection. Method: The competitive frequency-fluctuation characteristics of the dominant frequency in the band of 7-12 Hz in EEG and power density spectra of alpha band power-fluctuation were analyzed with a newer system of electroencephalofluctuographic technology in 20 patients (male 13, female 7, aged 17-37 years) with paroxysmal headache. Result: During episodes of headache in the affected sites the cumulated dominant fluctuation probability of each frequency components was in the order of 7, 8, 9, 10, 11, 12 Hz from high to low; The relative entropy value was 92.25% +/- 3.41%; Two peaks having at least 25% higher value than those of its neighbors were observed at 1.86 mHz and 4.65 mHz in power density spectra of power-fluctuation. During the intervals of episodes the above-mentioned probability character disappeared; The relative entropy value was decreased to 69.08% +/- 4.16% ; A new peak was found at 0.93 mHz in spectra power-fluctuation, with a reduction in peak value power at 4.65 mHz. Conclusion: It not only offered a parameter for pathophysiological and functional evaluation of paroxysmal headache, but also provided reference of the screening procedure for aircrew and astronaut selection.
