Sleep EEGs of 30 chronic insomnia patients are compared with the patients' subjective estimation of the duration of sleep and the number of waking periods during the night's recording. Overall, the patients overestimated the duration of sleep and, to a lesser degree, the time they awaken in the morning. The number and duration of waking periods in the night were regularly underestimated, and no correlation could be found between the estimated number of waking periods and those actually recorded on the EEG. The composition of sleep on falling asleep and on waking, when these are overestimated, showed an appreciable period of waking sleep at these times (21% and 41% respectively). The authors suggest that their results indicate that study of the transitional periods of sleep and waking may provide a better understanding of insomnia and lead to alternative therapeutic approaches. They also indicate that the shorter duration of sleep is only one aspect of insomnia and other factors are probably important.
将30名慢性失眠患者的睡眠脑电图与患者对睡眠时间的主观估计以及夜间记录期间的清醒次数进行比较。总体而言，患者高估了睡眠时间，并且在较小程度上高估了早晨醒来的时间。夜间清醒期的次数和时长经常被低估，并且在估计的清醒次数与脑电图实际记录的次数之间未发现相关性。入睡和醒来时的睡眠构成（当这些被高估时）在这些时候显示出明显的清醒睡眠期（分别为21%和41%）。作者表明，他们的结果表明，对睡眠与清醒过渡期的研究可能会更好地理解失眠并带来其他治疗方法。他们还指出，较短的睡眠时间只是失眠的一个方面，其他因素可能也很重要。
