“…Data from Sleep Disorders Institute showed that in subjects with approximately 20% of rapid eye movement (REM) sleep, 32% with various disorders will not correctly perceive their TST. Furthermore, subjects with the greatest TST misperception had the fewest number of stages shifts on the NPSG (Khan et al, 2009). Compared to subjects with underestimation of sleep, subjects with overestimation of sleep have significant higher daytime sleepiness (Trajanovic et al, 2007).…”

“…It is defined as a perceived total sleep time (TST) that is less than 80% of objective TST demonstrated in polysomnography (PSG) (Laranjeira et al, 2018). The misperception of TST was defined as abnormal if it was 2 or more standard deviation from the mean for each group studied (Khan et al, 2009). Misperception can also be differentiated by each sleep state such as wake after sleep onset, wake after sleep onset (WASO) or sleep onset latency (SOL) (Hermans et al, 2019).…”

Limited studies have examined arousal perception in obstructive sleep apnea (OSA) or other sleep disorders. The aim of this study is to evaluate the factors that affect patients' arousal and total sleep time perception. This is a retrospective study of 210 subjects divided into 5 groups: Primary insomnia; upper airway resistance syndrome (UARS)/primary snoring; mild, moderate and severe OSA. Perceived arousals were compared to objectively defined arousals. The subjects' age, body mass index (BMI), total sleep time (TST), perceived TST, sleep efficiency, stage shifts, rapid eye movement (REM) and delta time were compared. UARS/primary snoring group had significantly higher perceived arousal relative to arousal events and shorter total arousal duration than in primary insomnia and all OSA groups. There was a significant linear increase in total arousals and respiratory arousal as OSA severity increased. The number of perceived arousal events was negatively correlated with perception of TST. There was a trend for the insomnia group to have more perceived non-respiratory arousals compared with all OSA groups. Although subjects with UARS/primary snoring had the lowest total arousals, they perceived the highest arousals. The non-respiratory related arousals are probably perceived differently from respiratory arousal related perception. For the insomnia group to have more arousals not driven by respiratory events suggests that insomnia may be better defined as a disorder by being driven to arousals rather than apneas, who are aroused despite being driven towards sleep.
