As sleep latency is an important factor in the diagnosis of many disorders, it is important to know whether the patient's self-reported evaluation of sleep latency corresponds with an objectively measured evaluation. Some studies indicate that patients usually overestimate their sleep latency. We sought to determine how comorbidities affect the patient's ability to assess their sleep latency.
This was a retrospective study of 240 patients who had a polysomnography recorded at our sleep unit or at home in 2017-2020. Data on comorbidities were collected from hospital records.
Mean objective sleep latency (29.5 minutes, standard deviation [SD] 35.5) was significantly lower than self-reported sleep (37.4 minutes, SD 41.6) ( < .001). The patients who overestimated their sleep latency had higher mean apnea-hypopnea index (18.8 events/h, SD 21.6, vs 13.4 events/h, SD 12.8; = .04) and higher mean sleep efficiency (81.7%, SD 13.6%, vs 75.2%, SD 13.9%; = .004) than those who underestimated their sleep latency. There were significantly more patients with migraine in the overestimation group than in the underestimation group (20/159 patients vs 3/81 patients; = .035). This difference was not observed in patients with headache without migraine ( = 1.000).
We hypothesize that migraine is markedly associated with overestimation of sleep latency. This overestimation was not observed in patients with other headache types. Further studies are needed to explore the relation between migraine and sleep onset misperception.

由于睡眠潜伏期是许多疾病诊断的重要因素，因此了解患者对睡眠潜伏期的自我评估是否与客观测量的评估相符非常重要。一些研究表明，患者通常会高估自己的睡眠潜伏期。我们试图确定合并症如何影响患者评估自己睡眠潜伏期的能力。
这是一项回顾性研究，纳入了 2017 年至 2020 年间在我们的睡眠单位或家中进行多导睡眠图记录的 240 名患者。合并症的数据从医院记录中收集。
客观测量的平均睡眠潜伏期（29.5 分钟，标准差 [SD] 35.5）明显低于自我报告的睡眠潜伏期（37.4 分钟，SD 41.6）（<0.001）。高估自己睡眠潜伏期的患者平均呼吸暂停低通气指数（18.8 次/小时，SD 21.6，与 13.4 次/小时，SD 12.8；=0.04）和平均睡眠效率（81.7%，SD 13.6%，与 75.2%，SD 13.9%；=0.004）更高。在高估组中，偏头痛患者明显多于低估组（20/159 例患者与 3/81 例患者；=0.035）。在没有偏头痛的头痛患者中，没有观察到这种差异（=1.000）。
我们假设偏头痛与睡眠潜伏期的高估明显相关。在其他头痛类型的患者中，没有观察到这种高估。需要进一步研究来探讨偏头痛与睡眠起始感知障碍之间的关系。
