Polysomnographic changes of obsessive-compulsive disorder: evidence from case-control studies

Area of Science:

• Neuroscience
• Sleep Medicine
• Psychiatry

Background:

• Obsessive-compulsive disorder (OCD) is a mental health condition.
• Sleep disturbances are frequently reported in individuals with OCD.
• Polysomnography (PSG) is a diagnostic tool for sleep disorders.

Purpose of the Study:

• To compare polysomnographic (PSG) findings between patients with OCD and healthy controls.
• To identify specific sleep alterations associated with OCD.

Main Methods:

• A comprehensive literature search was performed across major scientific databases (MEDLINE, EMBASE, Web of Science, CNKI).
• Data were collected from inception up to September 2023.
• Pooled analyses and meta-regression were used to analyze polysomnographic data.

Main Results:

• Patients with OCD showed reduced sleep efficiency, total sleep time, and REM sleep latency.
• Increased awakening time, REM density, and REM intensity were observed in the OCD group.
• OCD severity and disease duration did not significantly influence these polysomnographic changes.

Conclusions:

• Significant polysomnographic alterations are evident in individuals with OCD.
• These findings highlight the importance of thorough PSG evaluation for sleep disturbances in OCD patients.
• Understanding sleep changes can inform clinical management and treatment strategies for OCD.
