Continuous performance test in drug-naïve patients with obsessive-compulsive disorder: a case-controlled study

Area of Science:

• Neuroscience
• Psychiatry
• Cognitive Psychology

Background:

• Obsessive-compulsive disorder (OCD) is a debilitating mental health condition.
• Cognitive deficits are often reported in OCD, but findings are inconsistent.
• Continuous Performance Test (CPT) is used to assess attention and executive functions.

Purpose of the Study:

• To investigate cognitive performance in drug-naïve OCD patients using the CPT.
• To explore the relationship between OCD symptom severity (obsessions vs. compulsions) and CPT performance.

Main Methods:

• Twenty drug-naïve OCD patients and matched controls completed the CPT.
• Performance metrics including sensitivity and other measures were analyzed.
• Correlation analyses examined the link between symptom scores and CPT performance.

Main Results:

• No significant differences were found between OCD patients and controls on overall CPT performance measures.
• Higher scores on obsession measures, not compulsion measures, were associated with reduced CPT sensitivity.
• This suggests a specific link between obsessive traits and attentional deficits.

Conclusions:

• Drug-naïve OCD patients do not exhibit generalized CPT deficits compared to controls.
• Obsessive symptoms, specifically, are linked to impaired sustained attention or sensitivity in OCD.
• These findings highlight the potential role of attentional dysfunction in the pathophysiology of OCD.
