35 hypersomniacs (20 with obstructive sleep apnea and 15 with narcolepsy) and 15 controls estimated sleep latency during systematic trials of attempting to remain awake during the day. The error in subjective assessment of sleep latency was more variable for both patient groups than for controls. In addition, narcoleptics could not provide a determination of sleep latency or differentiate sleep-wake states on nearly 23% of all trials. Ratings on a subjective sleepiness scale did not covary with objective sleep latency for any hypersomniac. The findings suggested that patients with either sleep apnea or narcolepsy had difficulty differentiating sleep and quiet wakefulness during the day.
35名睡眠过多者（20名患有阻塞性睡眠呼吸暂停，15名患有发作性睡病）和15名对照组人员在白天进行的一系列试图保持清醒的系统试验中估计了睡眠潜伏期。与对照组相比，两个患者组在睡眠潜伏期主观评估上的误差变化更大。此外，发作性睡病患者在近23%的试验中无法确定睡眠潜伏期或区分睡眠-清醒状态。对于任何睡眠过多者，主观嗜睡量表评分与客观睡眠潜伏期均无相关性。研究结果表明，患有睡眠呼吸暂停或发作性睡病的患者在白天难以区分睡眠和安静觉醒状态。
