Project description:ObjectivePreliminary studies suggest that repetitive transcranial magnetic stimulation (rTMS) may be an effective and tolerable intervention for adolescents with treatment-resistant depression. There is limited rationale to inform coil placement for rTMS dosing in this population. We sought to examine and compare three localization techniques for coil placement in the context of an open-label trial of high-frequency rTMS for adolescents with treatment-resistant depression.MethodsTen adolescents with treatment-resistant depression were enrolled in an open-label trial of high-frequency rTMS. Participants were offered 30 rTMS sessions (10 Hz, 120% motor threshold, left 3000 pulses applied to the dorsolateral prefrontal cortex) over 6-8 weeks. Coil placement for treatment was MRI guided. The scalp location for treatment was compared with the locations identified with standard 5 cm rule and Beam F3 methods.ResultsSeven adolescents completed 30 rTMS sessions. No safety or tolerability concerns were identified. Depression severity as assessed with the Children's Depression Rating Scale Revised improved from baseline to treatment 10, treatment 20, and treatment 30. Gains in depressive symptom improvement were maintained at 6 month follow-up visits. An MRI-guided approach for coil localization was feasible and efficient. Our results suggest that the 5 cm rule, Beam F3, and the MRI-guided localization approaches provided variable scalp targets for rTMS treatment.ConclusionsOpen-label, high-frequency rTMS was feasible, tolerable, and effective for adolescents with treatment-resistant depression. Larger, blinded, sham-controlled trials are needed for definitive safety and efficacy data. Further efforts to understand optimal delivery, dosing, and biomarker development for rTMS treatments of adolescent depression are warranted.

Project description:ImportanceRepetitive transcranial magnetic stimulation (rTMS) and transcranial direct current stimulation (tDCS) are both recognized as effective treatments for depression when applied individually. However, it is unknown whether rTMS combined with tDCS has better efficacy in the treatment of major depressive disorder (MDD).ObjectiveTo investigate the clinical effectiveness and safety of rTMS, tDCS, tDCS + rTMS, and sham tDCS + sham rTMS after 2 weeks of treatment in patients with MDD.Design, setting, and participantsThis double-blind, sham-controlled randomized clinical trial was conducted from November 2021 to April 2023 at 3 hospitals in China (Kangning Hospital affiliated with Ningbo University, Lishui Second People's Hospital, and Taizhou Second People's Hospital). Adult patients (aged 18-65 years) who were diagnosed with major depressive disorder were recruited. Participants were randomly assigned to 1 of 4 interventions: active tDCS + active rTMS, sham tDCS + active rTMS, active tDCS + sham rTMS, and sham tDCS + sham rTMS. Data analysis followed an intention-to-treat approach.InterventionPatients received a 2-week course of treatment. The tDCS was administered using a 2-mA direct current stimulator with electrodes placed on the left and right dorsolateral prefrontal cortex (DLPFC). Each tDCS session lasted 20 minutes and was conducted 30 to 60 minutes prior to the rTMS session for a total of 10 sessions. The rTMS was delivered at a frequency of 10 Hz using a figure-8 coil placed on the left DLPFC, with each session consisting of 1600 pulses. Treatments were administered 5 times per week for 2 weeks. Sham treatments were performed with a pseudostimulation coil and emitted only sound.Main outcomes and measuresThe primary outcome was the change in total score from baseline to week 2 on the 24-item Hamilton Depression Rating Scale (HDRS-24; score range: 0-52, with the highest score indicating more severe symptoms).ResultsA total of 240 participants (139 females [57.9%]; mean [SD] age, 32.50 [15.18] years) were included. As a primary outcome, patients who received active tDCS + active rTMS showed a significantly greater reduction in mean (SD) HDRS-24 total scores compared with patients in the other 3 groups (active tDCS + active rTMS: 18.33 [5.39], sham tDCS + active rTMS: 14.86 [5.59], active tDCS + sham rTMS: 9.21 [4.61], and sham tDCS + sham rTMS: 10.77 [5.67]; F3,236 = 35.79; η2 = 0.31 [95% CI, 0.21-0.39]; P < .001).Conclusions and relevanceThis trial found that tDCS + rTMS was a more effective and safe treatment option than either the tDCS or rTMS intervention alone for patients with MDD.Trial registrationChina Clinical Trial Registry Identifier ChiCTR2100052122.

Project description:Background: Major depressive disorder (MDD) is common in youth and treatment options are limited. We evaluated the effectiveness and safety of repetitive transcranial magnetic stimulation (rTMS) in adolescents and transitional aged youth with treatment resistant MDD. Methods: Thirty-two outpatients with moderate to severe, treatment-resistant MDD, aged 13-21 years underwent a three-week, open-label, single center trial of rTMS (ClinicalTrials.gov identifier NCT01731678). rTMS was applied to the left dorsolateral prefrontal cortex (DLPFC) using neuronavigation and administered for 15 consecutive week days (120% rest motor threshold; 40 pulses over 4 s [10 Hz]; inter-train interval, 26 s; 75 trains; 3,000 pulses). The primary outcome measure was change in the Hamilton Depression Rating Scale (Ham-D). Treatment response was defined as a >50% reduction in Ham-D scores. Safety and tolerability were also examined. Results: rTMS was effective in reducing MDD symptom severity (t = 8.94, df = 31, p < 0.00001). We observed 18 (56%) responders (≥ 50% reduction in Ham-D score) and 14 non-responders to rTMS. Fourteen subjects (44%) achieved remission (Ham-D score ≤ 7 post-rTMS). There were no serious adverse events (i.e., seizures). Mild to moderate, self-limiting headaches (19%) and mild neck pain (16%) were reported. Participants ranked rTMS as highly tolerable. The retention rate was 91% and compliance rate (completing all study events) was 99%. Conclusions: Our single center, open trial suggests that rTMS is a safe and effective treatment for youth with treatment resistant MDD. Larger randomized controlled trials are needed.

Project description:Repetitive transcranial magnetic stimulation (rTMS) has become a useful tool to treat different neuropsychiatric conditions such as depression, dementia and extrapyramidal syndromes insufficiently responding to conventional treatment. In this SHAM-controlled exploratory study safety, symptom improvement as well as changes in inflammation markers and neurotransmitter precursor amino acids availability were studied after a prefrontal cortex (PFC) stimulation using rTMS as add-on treatment in 29 patients with geriatric depression. Out of these, ten patients received SHAM treatment. Treatment was well tolerated, no serious adverse effects were observed. A clear improvement in symptoms of depression with a significant decrease in the HAMD-7 (U = 3.306, p = 0.001) was found by rTMS treatment. In parallel, serum phenylalanine dropped significantly (U = 2.340, p < 0.02), and there was a decline of tryptophan and of Phe/Tyr concentrations, both the effects, however, failed to reach the levels of statistical significance. In the patients who underwent SHAM treatment, no significant changes of HAMD-7 or the concentrations of any biomarker in the study could be found. In addition to the significant effect of rTMS on depression scores, these results point to a possible influence of rTMS on the enzyme phenylalanine hydroxylase (PAH), which plays a crucial role in the biosynthesis of neurotransmitter precursors related to geriatric depression.

Project description:ObjectivesThe authors previously reported that repetitive transcranial magnetic stimulation (rTMS) produced a response rate of 39.4% among 62 patients with treatment resistant vascular depression. This study was undertaken to assess the outcome of continuation therapy to prevent relapse among these patients during 9 weeks after completion of rTMS.DesignPatients were randomly assigned to 18,000 pulses of rTMS given over 3 weeks or sham treatment using double blind methods. After rTMS, all patients were given 20 mg/day of citalopram for 9 weeks and reevaluated at 3, 6, and 9 weeks.SettingOutpatient continuation treatment trial.ParticipantsPatients with vascular depression (N = 62), as determined by magnetic resonance imaging hyperintensities and three or more clinical risk factors for vascular disease without other major medical illness, were recruited. They had onset of major depression after age 50 and failed at least one trial of antidepressants.InterventionAfter rTMS or sham treatment, all treatment responders were given citalopram for 9 weeks.ResultsAmong the 33 patients who were given rTMS, 13 responded (i.e., >50% decline in Hamilton Depression Scale score). Of these 13, all completed the 9 weeks of continuation treatment. There were nine patients who continued to be responders and four who had a relapse of depression.ConclusionMore effective methods are needed to treat elderly patients with treatment resistant vascular depression and to prevent relapse among treatment responders.

Project description:Repetitive transcranial magnetic stimulation (rTMS) is an effective and safe treatment for depression; however, its potential has likely been hindered due to non-optimized targeting, unclear ideal stimulation parameters, and lack of information regarding how the brain is physiologically responding during and after stimulation. While neuroimaging is ideal for obtaining such critical information, existing modalities have been limited due to poor resolutions, along with significant noise interference from the electromagnetic spectrum. In this study, we used a novel diffuse optical tomography (DOT) device in order to advance our understanding of the neurophysiological effects of rTMS in depression. Healthy and depressed subjects aged 18-70 were recruited. Treatment parameters were standardized with targeting of the left dorsolateral prefrontal cortex with a magnetic field intensity of 100% of motor threshold, pulse frequency of 10 per second, a 4 s stimulation time and a 26 s rest time. DOT imaging was simultaneously acquired from the contralateral dorsolateral prefrontal cortex. Six healthy and seven depressed subjects were included for final analysis. Hemoglobin changes and volumetric three-dimensional activation patterns were successfully captured. Depressed subjects were observed to have a delayed and less robust response to rTMS with a decreased volume of activation compared to healthy subjects. In this first-in-human study, we demonstrated the ability of DOT to safely and reliably capture and compare cortical response patterns to rTMS in depressed and healthy subjects. We introduced this emerging optical functional imaging modality as a novel approach to investigating targeting, new treatment parameters, and physiological effects of rTMS in depression.

Project description:BackgroundPeripartum depression is a common disorder with very high potential hazards for both the patients and their babies. The typical treatment options include antidepressants and electroconvulsive therapy. However, these treatments do not ensure the safety of the fetus. Recently, repetitive transcranial magnetic stimulation has emerged as a promising treatment for neuropathies as well as depression. Nevertheless, many studies excluded pregnant women. This systematic review was conducted to confirm whether repetitive transcranial magnetic stimulation was a suitable treatment option for peripartum depression.MethodsWe performed a systematic review that followed the PRISMA guidelines. We searched for studies in the MEDLINE, PsycINFO, EMBASE, and Cochrane library databases published until the end of September 2020. Eleven studies were selected for the systematic review, and five studies were selected for quantitative synthesis. Data analysis was conducted using Comprehensive Meta-Analysis 3 software. The effect size was analyzed using the standardized mean difference, and the 95% confidence interval (CI) was determined by the generic inverse variance estimation method.ResultsThe therapeutic effect size of repetitive transcranial magnetic stimulation for peripartum depression was 1.394 (95% CI: 0.944-1.843), and the sensitivity analysis effect size was 1.074 (95% CI: 0.689-1.459), indicating a significant effect. The side effect size of repetitive transcranial magnetic stimulation for peripartum depression was 0.346 (95% CI: 0.214-0.506), a meaningful result. There were no severe side effects to the mothers or fetuses.ConclusionsFrom various perspectives, repetitive transcranial magnetic stimulation can be considered an alternative treatment to treat peripartum depression to avoid exposure of fetuses to drugs and the severe side effects of electroconvulsive therapy. Further research is required to increase confidence in the results.

Project description:IntroductionWhile repetitive transcranial magnetic stimulation (rTMS) is effective for 50-60% of those treatment-resistant depression, it is critical to identify predictors of response for optimal patient selection to improve therapy. Insomnia is a known symptom of depression that is both correlated with depression severity and associated with poor antidepressant response. Therefore, understanding this relationship may open new opportunities for the optimization of rTMS treatment. We aimed to explore whether baseline sleep quality, specifically insomnia, is associated with rTMS outcomes in a naturalistic sample of 975 patients (age 18-90; 63.9% F) receiving a standard course of rTMS treatment from two outpatient TMS clinics located within psychiatric hospitals in the United States. One site additionally collected information on concurrent medication use on 350 patients; among these, we examined whether pharmacological treatment of insomnia affected TMS treatment response.MethodsDepression was measured using the 30-item Inventory of Depressive Symptomology Self Report (IDS-SR) in site one and an abbreviated 16-item Quick Inventory of Depressive Symptomology (QIDS) derived from the IDS-SR in site two. Sleep disturbances were measured using three insomnia-related questions. Multilevel logistic regression was used to determine whether baseline insomnia scores were associated with TMS treatment outcome. Upon dichotomous categorization of the sample by insomnia and sleep-medication use, depression and sleep scores were analyzed across time using mixed repeated measures ANOVA.ResultsWe found that sleep quality improves after TMS (p<.001) and correlates with improvement in non-insomnia related depression symptoms (r= .318, p<.001). We found that among those who had significant insomnia at baseline, those not using sleep medications had significantly worse post-treatment IDS-SR scores compared to those using sleep medications (p=. 021) despite no difference in final insomnia score.DiscussionTogether, our results suggest that while baseline insomnia is not associated with TMS effectiveness, treating insomnia may affect the trajectory of TMS therapy. Future prospective studies are needed to examine the effect of insomnia treatment alongside TMS for depression.

Project description:BackgroundRepetitive transcranial magnetic stimulation (rTMS) can target specific neural circuits, which may allow for personalized treatment of depression. Treatment outcome is typically determined using sum scores from validated measurement scales; however, this may obscure differential improvements within distinct symptom domains. The objectives for this work were to determine: (1) whether a standard depression measure can be represented using a four symptom cluster model and (2) whether these symptom clusters had a differential response to rTMS treatment.MethodsData were obtained from two multi-centre randomized controlled trials of rTMS delivered to the left dorsolateral prefrontal cortex (DLPFC) for participants with treatment-resistant depression (TRD) conducted in Canada (THREE-D [Conducted between Sept 2013, and Oct 2016] and CARTBIND [Conducted between Apr 2016 and Feb 2018]). The first objective used confirmatory factor analytic techniques, and the second objective used a linear mixed effects model. Trial Registration: NCT01887782, NCT02729792.FindingsIn the total sample of 596 participants with TRD, we found a model consisting of four symptom clusters adequately fit the data. The primary analysis using the THREE-D treatment trial found that symptom clusters demonstrated a differential response to rTMS treatment (F(3,5984) = 31.92, p < 0.001). The anxiety symptom cluster was significantly less responsive to treatment than other symptom clusters (t(6001) = -8.02, p < 0.001). These findings were replicated using data from the CARTBIND trial.InterpretationThere are distinct symptom clusters experienced by individuals with TRD that have a differential response to rTMS. Future work will determine whether differing rTMS treatment targets have distinct patterns of symptom cluster responses with the eventual goal of personalizing rTMS protocols based on an individual's clinical presentation.FundingCanadian Institutes of Health Research, Brain Canada.

Project description:BACKGROUND:The management of late-life depression is challenged by high rates of treatment-resistance and adverse effects, along with medical comorbidities and polypharmacy. Together with the limited data on managing treatment-resistant depression in older adults, there is a need for investigating the efficacy of nonpharmacological treatment strategies. Repetitive transcranial magnetic stimulation (rTMS) is one modality that may better serve this patient population. METHODS:The present study examines data from two previous clinical trials (NCT00305045 and NCT01515215) to explore the efficacy of bilateral and unilateral high-frequency left-sided (HFL) rTMS in older adults suffering from treatment-resistant depression. A total of 43 adults aged 60 or older with a current major depressive episode were randomized to bilateral sequential, unilateral HFL, or sham. Bilateral sequential stimulation involved low-frequency (1 Hz) right dorsolateral prefrontal cortex (DLPFC) stimulation followed immediately by high-frequency (10 Hz) left DLPFC. The unilateral condition was HFL stimulation alone, and the placebo condition was either HFL or sequential bilateral form of sham. The primary outcome was remission of depression. RESULTS:Participants receiving bilateral rTMS experienced greater remission rates (40%) compared with unilateral (0%) or sham (0%) groups. Response to rTMS in the Hamilton Depression Rating Scale scores similarly favored the efficacy of bilateral rTMS. CONCLUSION:This study suggests that sequential bilateral treatment may be an optimal form of rTMS when used for treatment-resistant depression in older adults. Further large-scale comparative effectiveness trials of bilateral rTMS in this population are warranted.
