Challenging the Pleiotropic Effects of Repetitive Transcranial Magnetic Stimulation in Geriatric Depression: A Multimodal Case Series Study.

ABSTRACT:

Background

Although the antidepressant potential of repetitive transcranial magnetic stimulation (rTMS), the pleiotropic effects in geriatric depression (GD) are poorly investigated. We tested rTMS on depression, cognitive performance, growth/neurotrophic factors, cerebral blood flow (CBF) to transcranial Doppler sonography (TCD), and motor-evoked potentials (MEPs) to TMS in GD.

Methods

In this case series study, six drug-resistant subjects (median age 68.0 years) underwent MEPs at baseline and after 3 weeks of 10 Hz rTMS on the left dorsolateral prefrontal cortex. The percentage change of serum nerve growth factor, vascular endothelial growth factor, brain-derived growth factor, insulin-like growth factor-1, and angiogenin was obtained. Assessments were performed at baseline, and at the end of rTMS; psychocognitive tests were also repeated after 1, 3, and 6 months.

Results

Chronic cerebrovascular disease was evident in five patients. No adverse/undesirable effect was reported. An improvement in mood was observed after rTMS but not at follow-up. Electrophysiological data to TMS remained unchanged, except for an increase in the right median MEP amplitude. TCD and neurotrophic/growth factors did not change.

Conclusions

We were unable to detect a relevant impact of high-frequency rTMS on mood, cognition, cortical microcircuits, neurotrophic/growth factors, and CBF. Cerebrovascular disease and exposure to multiple pharmacological treatments might have contributed.

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: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:ObjectiveThere is conflicting published research about the clinical effectiveness of repetitive transcranial magnetic stimulation (rTMS) for the treatment of post-stroke depression (PSD). In order to provide trustworthy information for upcoming therapeutic treatments, this review attempts to compile and assess the data from pertinent systematic reviews and meta-analyses.MethodsThe systematic evaluation of repetitive transcranial magnetic stimulation for post-stroke depression was collected by searching CNKI, VIP, Wanfang Database, CBM, PubMed, EMBASE, Web of Science, and Cochrane Library. The retrieval time is from database construction to September 2022. After selection, the included literature was evaluated for methodological quality, reporting quality, and evidence quality using AMSTAR2, PRISMA statements, and the GRADE system.ResultsThere were a total of 13 studies included, with three having generally comprehensive reporting according to the PRISMA statement, eight having some reporting issues, two having pretty substantial information issues, and 13 having extremely poor methodological quality according to the AMSTAR2. The GRADE was used to grade the quality of the evidence, and the included literature had 0 high-level evidence, eight medium-level evidence, 12 low-level evidence, and 22 very low-level evidence.LimitationsThe results of this study are from researchers' subjective evaluation and only qualitative analysis, not quantitative evaluation. Although repeated cross-evaluation of researchers is carried out, the results will be personal. The interventions included in the study were complex, and it was impossible to analyze their effect values quantitatively.ConclusionPatients with post-stroke depression may benefit from repetitive transcranial magnetic stimulation. However, in terms of the quality of the reports, the methodology, and the quality of the evidence, published systematic evaluations/meta-analyses are of low quality. We list the drawbacks of the current clinical trials of repetitive transcranial magnetic stimulation for post-stroke depression as well as potential therapeutic mechanisms. This information may serve as a guide for future clinical trials aiming to establish a solid foundation for the clinical efficacy of repetitive transcranial magnetic stimulation in the treatment of post-stroke depression.
