The Sleep of Patients With Obsessive-Compulsive Disorder

Sleep Patterns in Patients with OCD

“…The polysomnographic findings of this study showed increased percentage of sleep time spent in stage I and HI sleep, which differs from the results obtained by Insel et al 5 and Rapoport et al, 20 who instead found a significant increase in stage IV percentage in patients with OCD. Our study found no significant difference in stage IV percentage between patient and control groups.…”

“…The Y-BOCS obsession subscale scores correlated positively with stage I percentage, SWS latency, and number of arousals, and correlated negatively with stage IV percentage and REM latency, all at a significant level. These findings differ from those obtained by Insel et al 5 and Hohagen et al, 21 who found that the severity of OCD had no relation to any sleep measures.…”

“…Only 33% of OCD patients in our study had sleep complaintseither interrupted sleep, difficulty to fall asleep, or hypersomnia. Only one patient attributed his insomnia to the compulsive rituals, which is contrary to the findings of Insel et al, 5 who found reported sleep complaints in 79% of OCD patients, noting that most of these sleep difficulties were subjectively connected with compulsive activities. Only two controls (11%) had sleep complaints, and these complaints did not meet criteria for sleep disorders.…”

The Mediating Role of Sleep Disturbances in the Relationship Between Obsessive-Compulsive Symptoms and Suicidal Ideation: The Moderating Effect of Childhood Trauma

“…This study con rmed a signi cant positive correlation between obsessive-compulsive symptoms and suicidal ideation, consistent with previous research ndings [7] .We further explored the role of sleep disorders in this relationship and found that sleep disorders not only directly affect emotional stability and increase the risk of suicidal ideation but also mediate the relationship between obsessivecompulsive symptoms and suicidal ideation.This nding reveals that sleep deprivation caused by obsessive-compulsive symptoms may impair cognitive functions, such as information processing and judgment, thereby increasing an individual's risk-taking and impulsive tendencies, which in turn contribute to the development of suicidal thoughts and behaviors.Speci cally, our analysis shows that obsessive-compulsive rituals and thoughts can lead to delayed bedtimes, consistent with ndings from other studies [20] .A signi cant proportion of OCD patients experience circadian rhythm sleep disorders and delayed sleep phase syndrome [21] .Compared to healthy controls, OCD patients have reduced total sleep duration and impaired sleep architecture [22] .Additionally, the positive correlation between sleep disorders and suicidal ideation [23] further underscores the crucial role of sleep problems in the relationship between obsessive-compulsive symptoms and suicide risk [24] . This study also further elucidated the impact of individual differences in the pathway from obsessivecompulsive symptoms to suicidal ideation, speci cally highlighting the moderating role of childhood trauma.…”

Sleep disturbances in obsessive-compulsive disorder: influence of depression symptoms and trait anxiety

“…The findings in longer sleep latency, measured as a component of PSQI and registering the time taken to fall asleep, in OCD patients replicate previous studies using self-report measures [9], as well as a meta-analysis of three studies conducted with PSG [10]. On the other hand, the lack of differences in sleep duration and sleep efficiency between both groups appears to contradict other reports with positive results [12][13][14], although in these studies, variations in sleep duration and sleep efficiency were determined using PSG. Therefore, discrepancies with these findings might be attributable to the use of different instruments to evaluate sleep function, as the PSQI does not correlate well with PSG [28], which is considered the gold standard objective measure of sleep.…”
