Recent studies have suggested that the onset of sleepwalking episodes may be preceded by fluctuations in slow-wave sleep electroencephalographic characteristics. However, whether or not such fluctuations are specific to sleepwalking episodes or generalized to all sleep-wake transitions in sleepwalkers remains unknown. The goal of this study was to compare spectral power for delta (1-4 Hz) and slow delta (0.5-1 Hz) as well as slow oscillation density before the onset of somnambulistic episodes versus non-behavioral awakenings recorded from the same group of sleepwalkers. A secondary aim was to describe the time course of observed changes in slow-wave activity and slow oscillations during the 3 min immediately preceding the occurrence of somnambulistic episodes.
Twelve adult sleepwalkers were investigated polysomnographically during the course of one night.
Slow-wave activity and slow oscillation density were significantly greater prior to patients' somnambulistic episodes as compared with non-behavioral awakenings. However, there was no evidence for a gradual increase over the 3 min preceding the episodes.
Increased slow-wave activity and slow oscillation density appear to be specific to sleepwalking episodes rather than generalized to all sleep-wake transitions in sleepwalkers.
近期研究表明，梦游发作之前可能会出现慢波睡眠脑电图特征的波动。然而，这种波动是否特定于梦游发作，还是在梦游者的所有睡眠-觉醒转换中普遍存在，目前尚不清楚。本研究的目的是比较同一组梦游者在梦游发作前与非行为性觉醒时，δ波（1-4赫兹）和慢δ波（0.5-1赫兹）的频谱功率以及慢振荡密度。第二个目的是描述在梦游发作前3分钟内观察到的慢波活动和慢振荡变化的时间进程。
在一个晚上对12名成年梦游者进行多导睡眠图检查。
与非行为性觉醒相比，患者梦游发作前的慢波活动和慢振荡密度显著更高。然而，在发作前3分钟内没有证据表明其逐渐增加。
慢波活动增加和慢振荡密度似乎特定于梦游发作，而非在梦游者的所有睡眠-觉醒转换中普遍存在。
