Many severely depressed patients do not benefit from or tolerate existing treatments. Repetitive transcranial magnetic stimulation (rTMS) has been reported to benefit depression. We compared rTMS to electroconvulsive therapy (ECT) in severely ill, depressed patients.
Twenty-five patients with a major depression (unipolar or bipolar) deemed clinically appropriate for ECT were randomly assigned to rTMS (10-20 treatments, 10 Hz, 110% motor threshold applied to the left dorsolateral prefrontal cortex for a total of 10,000-20,000 stimulations) or a course of bitemporal ECT (4-12 treatments). The primary outcome measure was the 24-item Hamilton Depression Rating Scale (HDRS). The Brief Psychiatric Rating Scale (BPRS), Young Mania Rating Scale (YMS), and Clinical Global Impression scale (CGI) were secondary measures. Minimal rescue medications were utilized.
Mean percent improvement on the baseline HDRS score did not significantly differ between the two treatments (i.e., 55% for the rTMS group vs. 64% for the ECT group [p = ns]). With response defined as a 50% reduction from baseline and a final score < or = 8 on the HDRS, there was also no significant difference between the two groups. We did not observe any differences between groups on the secondary measures.
A 2-4 week randomized, prospective trial comparing rTMS to ECT produced comparable therapeutic effects in severely depressed patients.

    • "With respect to the diagnosis, participants in all studies had a current diagnosis of Major Depressive Disorder (MDD). In two studies [26, 27], this included patients with a history of Bipolar Affective Disorder (BPAD). In two other studies [20, 28], information was unclear on whether patients with a previous history of BPAD were included. "

    ABSTRACT: Electroconvulsive therapy (ECT) is the longest standing psychiatric treatment available and has unequivocal benefit in severe depression. However this treatment comes with a number of side effects such as memory impairment. On the other hand, Repetitive Transcranial Magnetic Stimulation (rTMS) is a relatively new form of treatment which has been shown to be efficacious in patients suffering from a number of psychopathologies, including severe depression, with few reported side effects. Due to its potential therapeutic efficacy and lack of side effects, rTMS has gained traction in the treatment of depression, with a number of authors keen to see it take over from ECT. However, it is not clear whether rTMS represents a therapeutic alternative to ECT. This meta-analysis will therefore compare the “gold standard” treatment for severe depression, with the relatively new but promising rTMS. A literature search will be performed with the intention to include all randomised clinical trials. The null hypothesis is that there is no difference in the antidepressant efficacy between the two types of treatment modalities. Statistical analysis of Hamilton Depression Rating Scale (HDRS) scores will be performed.

    • "However, an overview of studies in the literature does not support an association between higher intensities (110% or 120% of motor threshold) and greater response rates. rTMS trials have moved in the direction of administering longer-duration protocols with greater doses of magnetic pulses [19-21]. These clinical studies suggest that treating depressed patients with higher doses improves response and remission rates with rTMS. "

    ABSTRACT: Objective Repetitive transcranial magnetic stimulation (rTMS) can enhance the excitement of the brain through adjusting the biological activities of the cerebral cortex and has wide biological effects, making it one basic mechanism of therapy for depression. In the treatment of unipolar depressive disorder, almost in every treatment method, hypomanic and manic shifts can be observed. There is still a lack of data regarding manic and hypomanic symptoms triggered by rTMS applications. Method We describe four cases with unipolar depression in which high-frequency rTMS over the left dorsolateral prefrontal cortex applied as an add-on antidepressive strategy may have induced a hypomanic episode. Results In these cases, 25 Hz rTMS combined with antidepressants may have contributed to the occurrence of hypomanic symptoms. Conclusion Using an intensive methodology of rTMS may induce hypomanic or manic symptoms.

    • "If several antidepressant treatment trials have been inefficient, even lower response rates after switching to other drugs may be observed [4]. Given the pervasive nature of depression and the need for more effective, safer, and more socially acceptable therapeutic strategies, alternative approaches are being investigated, such as repetitive transcranial magnetic stimulation (rTMS) [5].

    ABSTRACT: Major depression is one of the leading causes of disabling condition worldwide and its treatment is often challenging and unsatisfactory, since many patients become refractory to pharmacological therapies. Transcranial magnetic stimulation (TMS) is a non invasive neurophysiological investigation mainly used to study the integrity of the primary motor cortex excitability and of the cortico-spinal tract. The development of pairedpulse and repetitive TMS (rTMS) paradigms has allowed investigators to explore the pathophysiology of depressive disorders and other neuropsychiatric diseases linked to brain excitability dysfunctions. Repetitive transcranial magnetic stimulation has also therapeutic and rehabilitative capabilities since it is able to induce changes in the excitability of inhibitory and excitatory neuronal networks that may persist in time. However, the therapeutic effects of rTMS on major depression have been demonstrated by analyzing only the improvement of neuropsychological performance. The aim of this study was to investigate cortical excitability changes on twelve chronically-medicated depressed patients (test group) after rTMS treatment and to correlate neurophysiological findings to neuropsychological outcomes. In detail, we assessed different parameters of cortical excitability before and after active rTMS in the test group, then compared to those of ten age-matched depressed patients (control group) who underwent sham rTMS. In line with previous studies, at baseline both groups exhibited a significant interhemispheric difference of motor cortex excitability. This neurophysiological imbalance was then reduced in the patients treated with active rTMS, resulting also in a clinical benefit as demonstrated by the improvement in neuropsychological test scores. On the contrary, after sham rTMS, the interhemispheric difference was still evident in the control group. The reported clinical benefits in the test group might be related to the plastic remodeling of synaptic connection induced by rTMS treatment.
