Thirty-eight patients with cerebral vegetovascular crises of neurotic nature and 43 patients with neurogenic syncopes were examined. Use was made of clinical neurological analysis, electropolygraphic examinations in the state of awakeness and sleep, as well as of psychological tests (the method of versatile examination of personality). It was shown that in the patients with the vegetovascular crises the functioning of the activating nonspecific brain systems was intensified: this manifested itself in a lowering of the alpha-index on the EEG taken during awakeness, a delay of the orientation reaction, a shortening of the sleep duration, a diminution of the representation of the deep stages of the slow sleep, an acceleration of the heartbeat rate in all the functional states of the brain. This was accompanied by anxious-depressive and hypochondriacal emotional disturbances. In the patients with neurogenic syncopes, a certain intensification of the activation processes in the state of awakeness associated with moderate emotional changes was accompanied with a tendency to hyperactivation of the synchronizing systems during sleep. In these patients some epileptimorph changes were revealed on the EEGs of awakeness and sleep, while in the patients with vegetovascular crises no changes of such kind were observed.
对38例患有神经质性脑植物血管危象的患者和43例患有神经源性晕厥的患者进行了检查。采用了临床神经学分析、清醒和睡眠状态下的脑电图检查以及心理测试（人格综合检查法）。结果显示，患有植物血管危象的患者中，非特异性脑激活系统的功能增强：这表现为清醒时脑电图上α指数降低、定向反应延迟、睡眠时间缩短、慢波睡眠深度阶段的表现减少、在大脑的所有功能状态下心率加快。同时伴有焦虑抑郁和疑病性情绪障碍。在患有神经源性晕厥的患者中，清醒状态下与适度情绪变化相关的激活过程有一定增强，同时睡眠期间同步系统有过度激活的倾向。在这些患者的清醒和睡眠脑电图上发现了一些癫痫样改变，而在患有植物血管危象的患者中未观察到此类改变。
