BACKGROUND: Deep brain stimulation (DBS) is effective for refractory obsessive-compulsive disorder (OCD). Post-operative cognitive behavioral therapy (CBT) may augment the effects of DBS, but previous results are conflicting. Here, we investigated whether CBT augments the effect of DBS for OCD.
METHOD: Patients with and without CBT following DBS of the ventral anterior limb of the internal capsule were included. First, we analyzed Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) and Hamilton Depression Rating Scale (HAM-D) scores before, during and after CBT in all patients with CBT. Second, we matched patients with and without CBT based on clinical baseline variables and initial response to DBS and compared the course of Y-BOCS and HAM-D scores over the same timeframe.
RESULTS: In total, 36 patients with and 16 patients without CBT were included. Average duration of CBT was 10.4 months (s.d. 6.4). In the 36 patients with CBT, Y-BOCS scores decreased on average by 3.8 points (14.8%) from start until end of CBT (p = 0.043). HAM-D scores did not decrease following CBT. Second, 10 patients with CBT were matched to 10 patients without CBT. In both groups, Y-BOCS scores decreased equally from start until end of CBT or over a similar timeframe (10% in CBT group v. 13.1% in no-CBT group, p = 0.741).
CONCLUSIONS: Obsessive-compulsive symptoms decreased over time in patients with and without post-operative CBT. Therefore, further improvement may be attributed to late effects of DBS itself. The present study emphasizes the need for prospective randomized controlled studies, examining the effects of CBT.
