In this study 201 EEG curves are interpreted belonging to patients suffering from incipient disturbances of the cerebral circulation. The patients were divided into 3 groups according to age (group I, 30-40 years; group II, 40-50 years; group III, 50 years and over). In group I there prevailed a rate of 11-12 alpha waves per sec., and a slower rate was hardly ever found; in group III the frequency pattern was quite different. This decreased frequency of the waves could be confirmed by statistics. We believe a direct link can be assumed to exist between a decrease in frequency and the beginning of disturbed cerebral circulation.
在本研究中，对201例脑循环早期紊乱患者的脑电图曲线进行了解读。患者按年龄分为3组（第一组，30 - 40岁；第二组，40 - 50岁；第三组，50岁及以上）。在第一组中，每秒有11 - 12次α波占主导，很少发现较慢的频率；在第三组中，频率模式则大不相同。这种波频率的降低可以通过统计得到证实。我们认为，可以假定频率降低与脑循环紊乱的开始之间存在直接联系。
