Abstract

Insomnia was found to be highly prevalent among individuals with obsessive-compulsive disorder, with greater symptom severity linked to it.

  • Obsessive-compulsive disorder is often associated with sleep disturbances, particularly insomnia and circadian dysregulation.
  • Greater symptom severity in obsessive-compulsive disorder is linked to the presence of insomnia, especially regarding intrusive thoughts.
  • Circadian disruptions, including delayed sleep phase and evening chronotype, are frequently observed in individuals with obsessive-compulsive disorder.
  • These circadian alterations are associated with emotional instability and variability in clinical symptoms.
  • Systematic assessment of sleep-related disturbances may be important for managing obsessive-compulsive disorder.
