Introduction
We previously reported that deep brain stimulation (DBS) in the anterior limb of the internal capsule/bed nucleus of the stria terminalis (IC/BST) is effective in reducing symptoms in severe treatment-resistant obsessive-compulsive disorder patients.
ObjectiveTo examine the long-term evolution of obsessive compulsive disorder (OCD) symptoms in 24 patients treated with chronic electrical stimulation in IC/BST.
AimsWe aimed to examine the evolution of the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) and to determine if a number of predictors assessed before surgery are significantly related to this evolution.
MethodsWe used a linear mixed model to investigate the evolution of the Y-BOCS in 24 patients. Data was collected in a naturalistic manner. Seven hundred measurements, taken during a total of 1836 follow-up months, are included in this analysis.
ResultsOur analysis showed a long-term, sustained effect of electrical stimulation in the IC/BST. After a fast initial decline of OCD symptoms, these symptoms stay relatively stable. In addition, results show a strong ON/OFF effect of stimulation (e.g., due to battery depletion). Beside the ON/OFF effect of stimulation, the surgery itself has no additional effect on OCD symptoms. The Beck Depression Inventory (BDI) at baseline was the only predictor significantly related to the evolution of the Y-BOCS. A higher BDI at baseline seemed to be related to a smaller decrease of the Y-BOCS over time.
ConclusionElectrical stimulation in the IC/BST has a fast and sustained effect on OCD symptoms.
