Migraine may disturb sleep perception during sleep onset: a retrospective data analysis

Abstract

Study Objectives: 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. Methods: 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. Results: 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) (P
