Cognitive behavioral therapy in patients with deep brain stimulation for obsessive-compulsive disorder: a matched...

Area of Science:

• Neurosurgery
• Psychiatry
• Cognitive Behavioral Therapy

Background:

• Deep brain stimulation (DBS) is a recognized treatment for refractory obsessive-compulsive disorder (OCD).
• The role of post-operative cognitive behavioral therapy (CBT) in enhancing DBS outcomes for OCD remains unclear, with conflicting prior findings.
• This study aimed to clarify whether CBT augments the therapeutic effects of DBS in OCD patients.

Purpose of the Study:

• To evaluate the efficacy of post-operative cognitive behavioral therapy (CBT) in augmenting deep brain stimulation (DBS) for obsessive-compulsive disorder (OCD).
• To compare treatment outcomes in OCD patients who received DBS with and without adjunctive CBT.

Main Methods:

• Retrospective analysis of patients undergoing DBS for OCD, comparing those with and without post-operative CBT.
• Assessment of Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) and Hamilton Depression Rating Scale (HAM-D) scores.
• Matched-pair analysis comparing outcomes between groups with and without CBT, controlling for baseline variables and initial DBS response.

Main Results:

• In patients receiving CBT, Y-BOCS scores showed a statistically significant decrease (14.8%, p=0.043), while HAM-D scores did not.
• Matched analysis of 10 patients with CBT and 10 without revealed no significant difference in Y-BOCS score reduction over similar timeframes (10% vs. 13.1%, p=0.741).
• Obsessive-compulsive symptoms improved over time in both groups, irrespective of CBT administration.

Conclusions:

• Obsessive-compulsive symptoms improved in patients with and without post-operative CBT, suggesting late-acting effects of DBS itself.
• The study did not find evidence that CBT significantly augments DBS outcomes for OCD.
• Further investigation through prospective randomized controlled trials is warranted to definitively assess the impact of CBT on DBS efficacy in OCD.
