Groups of 12 normal and insomniac male subjects aged 55 to 71 yr. were sleep deprived for 64 hr. In both groups, the sleep loss was preceded by four baseline sleep nights and followed by four recovery nights. Reaction time, immediate recall, sleepiness, and body temperature were measured at approximately 2300, 0115, 0330, 0530, and 0800 during baseline, deprivation and recovery nights. Significant performance or mood differences were not found between the normal and insomniac males on any measure or at any testing period throughout the study. Performance of both groups declined characteristically during sleep loss while subjective sleepiness increased. As in young adults, degraded performance was restored by 8 hr. of recovery sleep. However, subjective sleepiness did not return to baseline levels until early in the second recovery night. It was concluded that chronic insomnia does not result in group performance deficits similar to those seen after chronic sleep loss; and the restorative function of sleep operates as efficiently in older insomniac subjects (who apparently have reduced need to sleep) as in older normal subjects.
将12名年龄在55至71岁之间的正常男性受试者和失眠男性受试者分为一组，剥夺他们64小时的睡眠。在两组中，在睡眠剥夺之前有四个基线睡眠夜晚，之后有四个恢复夜晚。在基线、剥夺和恢复夜晚期间，大约在23:00、01:15、03:30、05:30和08:00测量反应时间、即时回忆、嗜睡程度和体温。在整个研究过程中的任何测量或测试阶段，正常男性和失眠男性之间在表现或情绪方面均未发现显著差异。两组的表现均在睡眠剥夺期间典型地下降，而主观嗜睡程度增加。与年轻人一样，8小时的恢复睡眠使下降的表现得以恢复。然而，主观嗜睡程度直到第二个恢复夜晚的早些时候才恢复到基线水平。得出的结论是，慢性失眠不会导致与慢性睡眠剥夺后类似的群体表现缺陷；并且睡眠的恢复功能在年长的失眠受试者（他们显然睡眠需求减少）中与在年长的正常受试者中一样有效。
