Background:
Of late, the interest in accelerated treatment protocols in repetitive transcranial magnetic stimulation (TMS) for the treatment of depression and obsessive-compulsive disorder (OCD) has been gaining momentum. Studies have already found that the patterned theta burst stimulation is non-inferior to the standard highfrequency stimulation in treating depression. The objective of the present study was to evaluate the clinical efficacy of a customized accelerated combination TMS naturalistic setting.
Objective:
The objective of the present study was to assess the efficacy of our accelerated protocol on the clinical outcomes in MDD and OCD, when the pharmacotherapy is maintained as usual. The outcome measures selected were day 6 Hamilton Depression Rating Scale with 21 items (HAM-D) and day 10 Yale-Brown Obsessive Compulsive Scale (Y-BOCS) for MDD and OCD respectively, as compared to their day one scores.
Methods:
Retrospective analysis of pre and post-deep repetitive TMS responses in depression and OCD patients was performed. About 391 Depression and 239 OCD patients’ data was analyzed. Customized treatment protocols consisted of twice daily high-frequency stimulations intervened by one theta burst stimulation. The outcome measures were a day six score in depression and a day 10 score in OCD, compared to day one baseline scores.
Results:
The overall response rate in depression was 60.86%, estimated as a >50% reduction in the Hamilton Depression Rating Scale (HAM-D) 21 items score, and 62.76% in OCD, estimated as a >35% reduction in the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) score. The mean reduction of YBOCS and HAM-D was statistically significant at p<0.0001. Corresponding effect size estimations revealed Cohen’s d value of 1.40 and 1.59, respectively.
Conclusions:
The response rates achieved at day six and day 10 in depression and OCD, respectively, were comparable to previous studies employing standard treatment protocols. The accelerated protocol produced satisfactory short-term clinical outcomes that were effective in the early management of the illness without any serious adverse effects.
