Objective: Major depressive disorder (MDD) which comes to transcranial magnetic stimulation (TMS) is prone to relapse. Cluster maintenance (CM) TMS is courses of 5 treatments delivered over 2.5-5 days, separated by monthly or greater non-treatment periods. Our aim was to characterize the outcomes of 100 courses of CM TMS., Method: This was a Quality Assurance/Clinical Audit study. We studied consecutive CM TMS courses provided to private hospital inpatients. Mood was rated (on admission and discharge) using the six-item Hamilton depression rating (HAMD6) and the Clinical Global Impression - Severity (CGI-S) scales. We also applied recent STAR*D criteria which are designed to measure the 'clinical change' expected to impact patient function [16]., Results: For the total sample, using the HAMD6, 83% of courses featured relapse or partial relapse on admission, and 81% featured remission on discharge. Of 46 courses featuring HAMD6 relapse on admission, 74% featured remission on discharge. For the 100 courses the HAMD6 discharge scores were significantly lower than the admission scores (p = 2.0 × 10 -24 ), as were the CGI-S scores (p = 1.8 × 10 -25 ). Using STAR*D criteria for people in relapse or partial relapse on admission, CM TMS provided least a 'clinically meaningful' outcome in 82% of the cases., Conclusion: For courses featuring relapse or partial relapse on admission, CM TMS converted greater than 70% to remission at discharge. It produced statistically significant reductions in HAMD6 and CGI-S scores, and using STAR*D criteria, at least 'clinically meaningful' change was extensively demonstrated. This evidence indicates CM TMS should be readily available to people living with relapsing MDD., (Copyright © 1964–2022 by MedWorks Media Inc, Los Angeles, CA All rights reserved.

Objective: To examine reports of Transcranial Magnetic Stimulation (TMS) during pregnancy for evidence of fetal risk., Method: PubMed was used to locate relevant literature for the years 1998-2020 and reference lists were examined for materials not located electronically., Results: Ten reports were located dealing with 67 births over 20 years. Stimulation was applied is all trimesters, at low and high frequency, and as intermittent theta-burst stimulation. No mother or baby experienced a serious event., Conclusions: Certainty awaits large, standardized studies. However, the available reports provide no evidence that TMS to mother during pregnancy has detrimental effects on the fetus.

Objective: Transcranial magnetic stimulation is an emerging treatment of treatment-resistant depression. Current protocols rely on daily treatments. This study was designed to determine whether the time period over which treatment is delivered is an important factor in efficacy., Method: Sixteen adult patients with treatment-resistant major depression were randomly assigned to one of the two treatment groups, both of which received 2 weeks of treatment. One group received daily treatment (10 treatments, on business days). The other group received three treatments in week one, and two treatments in week two (five treatments, on spaced business days). Mood was rated using the Hamilton Depression Rating Scale (HDRS) and a self-rated visual analogue scale. Response was defined as a 50% reduction in HDRS rating, and remission was defined as achieving an HDRS score of 8 or less. The groups were compared throughout the 2-week study period., Results: At entry, there were no demographic differences between the groups. Multivariate tests showed a significant main effect for time (Pillai trace=0.76, F(4,56)=8.56, p<0.001, power=0.99) reflecting the improvement in both measures of depression during treatment. There was no significant difference between the groups overall (Pillai trace=0.25, F(2,13)=2.12, p=0.16, power=0.36). Additionally, there was no significant interaction between time and treatment group (Pillai trace=0.18, F(4,56)=1.35, p=0.26, power=0.39) indicating that the significant improvement in depression over time was similar for both treatment groups. There were no significant differences in response and remission rates between the groups., Conclusion: The time period of treatment appeared to be an important outcome factor. This suggests that less than daily transcranial magnetic stimulation treatment may be a useful clinical alternative.

Background: Major depressive disorder (MDD) is frequently chronic and relapsing. The use of maintenance or continuation transcranial magnetic stimulation (TMS) has received clinical and some research support. Objective: To conduct a case series study to report the outcomes of once-weekly (OW) or once-fortnightly (OF) continuation TMS in a real-life setting. Methods: We offered OW or OF TMS sessions to patients with MDD in remission or partial remission/relapse. Results: Ten patients received OW TMS and four received OF TMS, for 8 to 46 weeks. No patients in either group who were in remission or partial remission at baseline experienced a relapse. Improvements in HAMD6 and CGI-S scores were statistically significant or of borderline significance for the total sample and the OW group. Conclusions: This naturalistic, open-label observational study indicates that OW TMS is effective as maintenance therapy in MDD, while also offering some support for OF TMS maintenance in preventing relapse.

Objective: To determine the impact of clustered maintenance transcranial magnetic stimulation (TMS) on irritability occurring in treatment-resistant major depressive disorder (MDD).Method: A naturalistic study of 106 courses that includes pre- and posttreatment assessments of subjective and objective depression and a subjective measure of irritability developed for this study.Results: Forty-six participants (35 females), mean age 43.2 years (14.3), completed 106 courses. There was a significant reduction in irritability and depression scores (p < .001). The change in irritability scores was significantly correlated with the change in depression scores, r = .40, p < .001.Conclusion: TMS has the capacity to reduce the irritability co-occurring with treatment-resistant MDD, known to be responsive to TMS. This increases the possibility of using TMS in the treatment of irritability co-occurring with other disorders or standing alone (should irritability be categorized as a stand-alone disorder).

Background: Various TMS protocols have been described, none is appropriate in all circumstances. Objective: To describe the response of a person with acute MDD treated with TMS who was only available for treatment on 3 consecutive days per week. Method: 5 treatment sessions were provided over 3 days – this was provided 4 times, separated by no-treatment periods of 4 days. HAMD6, CSI-S and VAS for depression were completed on the first and last day of each 3-day treatment series. Results: Remarkable improvement; the HAMD6 fell from 12 (severe depression) to 0, the CGI-S fell from 5 (Markedly ill) to 1 (Normal, not mentally ill) and the VAS fell by 98%. There was clear improvement during the last 3 treatment series, as well as during all 3 no-treatment periods. Conclusion: Should these findings be replicated, an additional, useful protocol may be established. [ABSTRACT FROM AUTHOR]

Transcranial magnetic stimulation (TMS) was used to study the postexercise facilitation of 11 normal subjects on eight occasions. Between individuals, there was almost a sixfold difference in facilitation. The greatest positive percentage change for any individual was 61%, and the greatest negative percentage change was 51%. The results suggest that facilitation is a durable individual characteristic of normal subjects. Serial studies may therefore be indicated in monitoring individ-uals suffering relapsing conditions.
