The sleep/wake patterns of 16 institutionalized demented women were visually monitored hourly for 14 consecutive days. Individual mean total sleep time varied markedly from 5.0 to 12.1 hours per 24 hours. Unexpectedly, amounts of day sleep and night sleep correlated positively, suggesting a general sleep tendency manifested throughout the 24-hour day. Consistent individual sleep patterns and high inter-day correlations were found. A high degree of individuality in the sleep/wake patterns was also found, contrary to expectations that elderly obtain less sleep than others. Night sleep in the institutionalized elderly was not lessened by daytime sleep. Visual monitoring of sleep/wake patterns generated reliable data.
对16名住在养老院的患痴呆症女性的睡眠/清醒模式进行了连续14天的每小时一次的视觉监测。个体平均总睡眠时间差异显著，每24小时从5.0小时到12.1小时不等。出乎意料的是，白天睡眠时间和夜间睡眠时间呈正相关，这表明在整个24小时内存在一种普遍的睡眠倾向。发现了一致的个体睡眠模式和较高的日间相关性。还发现睡眠/清醒模式具有高度的个体差异，这与老年人睡眠比其他人少的预期相反。养老院中老年人的夜间睡眠并没有因白天睡眠而减少。对睡眠/清醒模式的视觉监测产生了可靠的数据。
