Abstract:Objectives:To investigate the current response to psychopharmacology and transcranial magnetic stimulation (TMS) in Pacific Islander adolescents with Major Depressive Disorder (MDD).BACKGROUND:40-60% of youth with Major Depressive Disorder (MDD) have a limited response to current treatment protocols and require either (a) medications with a wider side effect profile, (b) intensive psychosocial programs that interfere with school, and/or (c) publicly spurned options (electroconvulsive therapy). Such results are tempered further when working with Pacific Islanders, as such youth and families have shown in multiple studies. The aversion to such standard treatment is concerning, as Native Hawaiian adolescents have a higher risk of suicide than other adolescents in Hawaii (12.9/100,000 youth per year). With this in mind, the investigators wondered how a novel, non-pharmacological approach to depression treatment in children, transcranial magnetic stimulation (TMS), would fair.METHODS:2 literature searches (utilizing Pubmed, Ovid, Google Scholar, and OneSearch) were conducted on 6/10/19: 1 investigating rTMS in adolescent depression, the other researching rTMS in depression in Native Hawaiian or other Pacific Islander youth.RESULTS:At this point in time, 10 studies exist testing TMS’ effects in children and adolescents with treatment refractory depression. 9 of said studies were open-label trials; 1 was a small (n=2) RCT (with both patients randomized to the active arm). Of those evaluating depression severity through Children’s Depression Rating Scale-revised (“CDRS-R”) scores, 100% of the trials (8/8) displayed a statistically significant improvement. None of the trials of the 1st series of searches nor the entirety of the 2nd series yielded information as to how TMS fairs in Native Hawaiian or other Pacific Islander youth.CONCLUSIONS:No studies exist that can verify the efficacy of TMS in youth, of Oceanic origin or otherwise, with the same degree of scrutiny as currently done in adults. Therefore, our group is engaging in a pilot study to evaluate the performance of TMS for the treatment of MDD in Native Hawaiian and other Pacific Islander adolescents aged 12-17; we are planning on then progressing on to a sham-controlled RCT in a larger sample size of the same population to test its efficacy in not just Pacific Islanders, but all youth.Funding Acknowledgements:no funding

Abstract Background The goal of this study was to examine baseline transcranial magnetic stimulation measures of cortical inhibition and excitability in depressed patients and characterize their longitudinal posttreatment changes. Methods Fifteen adolescents (age 13–17 years) with moderate to severe major depressive disorder and 22 healthy controls (age 9–17) underwent single- and paired-pulse transcranial magnetic stimulation and clinical assessments. Transcranial magnetic stimulation measures included short-interval intracortical inhibition (2 and 4 milliseconds), long-interval intracortical inhibition (100, 150, and 200 milliseconds), cortical silent period, and intracortical facilitation (10, 15, and 20 milliseconds). Ten participants with major depressive disorder initiated antidepressant treatment or had dose adjustments. These participants were reassessed after treatment. Depression symptom severity was measured with the Children’s Depression Rating Scale, Revised. Robust regression modeling compared healthy and depressed adolescents at baseline. Relationships between changes in cortical inhibition and changes in depressive symptom severity were assessed in the depressed adolescents receiving antidepressant treatment. Results Our results revealed that at baseline, short-interval intracortical inhibition-2 was significantly reduced (Padj = .01) in depressed participants, suggesting impaired cortical inhibition compared with healthy controls. At follow-up, improvement in Children’s Depression Rating Scale, Revised scores correlated with improvement in short-interval intracortical inhibition-4 amplitude (greater inhibition) after antidepressant treatment (R2 = 0.63; P = .01). Conclusions These results suggest that cortical inhibition measures may have promise as biomarkers in adolescents treated for depression.

Background: Studies have implicated hypofrontality in the pathogenesis of impaired theory of mind (ToM) and executive function (EF) in major depressive disorder (MDD). These symptoms are usually resistant to treatment. Repetitive transcranial magnetic stimulation (rTMS) has been shown to reverse hypofrontality. Moreover, BDNF is an effective biomarker of antidepressant effects, but there have been very few studies on the correlation between BDNF and rTMS. We aimed to evaluate the efficacy of 20 sessions of a 10 Hz unilateral rTMS intervention over the left dorsolateral prefrontal cortex (DLPFC) in improving ToM and EF in patients with MDD and its correlation with BDNF. Methods: A total of 120 MDD patients were enrolled in this randomized, sham-controlled, double-blind trial. Each participant received 20 sessions of rTMS at 10 Hz frequency through the active or the sham coil over 4 weeks. ToM was assessed with the facial emotion identification test (FEIT) and hinting task (HT). EF was assessed with the Wisconsin card sorting test (WCST). BDNF assessments were carried out at baseline and 2-, 4-, 12-, and 24-week follow-ups. Results: The improvement in the ToM (FEIT, HT) in the active rTMS group was significantly different from that in the sham rTMS group (F = 18.09, p < 0.001; F = 5.02, p = 0.026). There were significant differences in the WCST (categories completed, response errors, response perseverative errors, non-response perseverative errors) after logarithmic transformation at different time points in the active rTMS group (F = 14.71, p < 0.001; F = 5.99, p = 0.046; F = 8.90, p = 0.031; F = 2.31, p = 0.048). However, there was no significant difference in log transformed BDNF concentration between the two groups (t = 0.07 to t = 1.29, p > 0.05). BDNF was negatively correlated with WCST categories completed at the 24th week (r = −0.258, p = 0.046). Conclusions: The results show that rTMS may improve the ToM and EF of patients with MDD and there was no significant correlation with serum BDNF concentration. RTMS can not only be used for treatment of patients with MDD but also has a positive effect on ToM and EF.
