ABSTRACT We tested whether transcranial magnetic stimulation (TMS) over the left dorsolateral prefrontal cortex (DLPFC) is effective and safe in the acute treatment of major depression.
In a double-blind, multisite study, 301 medication-free patients with major depression who had not benefited from prior treatment were randomized to active (n = 155) or sham TMS (n = 146) conditions. Sessions were conducted five times per week with TMS at 10 pulses/sec, 120% of motor threshold, 3000 pulses/session, for 4-6 weeks. Primary outcome was the symptom score change as assessed at week 4 with the Montgomery-Asberg Depression Rating Scale (MADRS). Secondary outcomes included changes on the 17- and 24-item Hamilton Depression Rating Scale (HAMD) and response and remission rates with the MADRS and HAMD.
Active TMS was significantly superior to sham TMS on the MADRS at week 4 (with a post hoc correction for inequality in symptom severity between groups at baseline), as well as on the HAMD17 and HAMD24 scales at weeks 4 and 6. Response rates were significantly higher with active TMS on all three scales at weeks 4 and 6. Remission rates were approximately twofold higher with active TMS at week 6 and significant on the MADRS and HAMD24 scales (but not the HAMD17 scale). Active TMS was well tolerated with a low dropout rate for adverse events (4.5%) that were generally mild and limited to transient scalp discomfort or pain.
Transcranial magnetic stimulation was effective in treating major depression with minimal side effects reported. It offers clinicians a novel alternative for the treatment of this disorder.

    ABSTRACT: Context The aim of this study was to assess whether the combination of low frequency repetitive transcranial magnetic stimulation (rTMS) and venlafaxine (150-225 mg/day) is effective and safe for treatment-resistant unipolar depression (TRD). Method In a multicenter (18 centers) randomized double blind controlled trial with three arms, 170 patients were allocated to receive active rTMS combined with active venlafaxine (n= 55), active rTMS combined with placebo venlafaxine (n= 60) or sham rTMS combined with active venlafaxine (n= 55). The patients received once daily sessions of active or sham 1Hz rTMS applied over the right dorsolateral prefrontal cortex (360 pulses/day delivered at 120% of the resting motor threshold) for two to six weeks; rTMS was combined with active or sham venlafaxine (mean dose: 179.0 ± 36.6 mg/day). The primary outcome was the number of patients who achieved remission, which was defined as an HDRS-17 score < 8. Results We reported a similar significant antidepressant effect in the 3 groups (p< 10-6), with a comparable delay of action and a comparable number of remitters at the endpoint (28% in the combination group, 41% in the rTMS group and 43% in the venlafaxine group; p= 0.59). Conclusion Low frequency rTMS appears to be as effective as venlafaxine and as effective as the combination of both treatments for TRD. Because of its short session duration (the duration of one session was 8.5 minutes) and its safety, slow rTMS might be a useful alternative treatment for patients with TRD.

    ABSTRACT: Background Transcranial magnetic stimulation (TMS) allows to manipulate neural activity non-invasively, and much research is trying to exploit this ability in clinical and basic research settings. In a standard TMS paradigm, single-pulse stimulation over motor cortex produces repetitive responses in descending motor pathways called I-waves. However, the details of how TMS induces neural activity patterns in cortical circuits to produce these responses remain poorly understood. According to a traditional view, I-waves are due to repetitive synaptic inputs to pyramidal neurons in layer 5 (L5) of motor cortex, but the potential origin of such repetetive inputs is unclear. Objective/Hypothesis Here we aim to test the plausibility of an alternative mechanism behind D- and I-wave generation through computational modeling. This mechanism relies on the broad distribution of conduction delays of synaptic inputs arriving at different parts of L5 cells’ dendritic trees and their spike generation mechanism. Methods Our model consists of a detailed L5 pyramidal cell and a population of layer 2 and 3 (L2/3) neurons projecting onto it with synapses exhibiting short-term depression. I-waves are simulated as superpositions of spike trains from a large population of L5 cells. Results Our model successfully reproduces all basic characteristics of I-waves observed in epidural responses during in vivo recordings of conscious humans. In addition, it shows how the complex morphology of L5 neurons might play an important role in the generation of I-waves. In the model, later I-waves are formed due to inputs to distal synapses, while earlier ones are driven by synapses closer to the soma. Finally, the model offers an explanation for the inhibition and facilitation effects in paired-pulse stimulation protocols. Conclusions In contrast to previous models, which required either neural oscillators or chains of inhibitory interneurons acting upon L5 cells, our model is fully feed-forward without lateral connections or loops. It parsimoniously explains findings from a range of experiments and should be considered as a viable alternative explanation of the generating mechanism of I-waves.

    ABSTRACT: Transcranial magnetic stimulation (TMS) of the dorsolateral prefrontal cortex (DLPFC) is increasingly used as a non-invasive treatment for medication-resistant depression. However, this target site is commonly localized using an inaccurate standard procedure, which uses a fixed distance with respect to the motor cortical site for optimal stimulation of a hand muscle. Several studies have suggested this 5-cm distance is in average too short to reliably target the DLPFC, while others just found the opposite. Nevertheless, they all agree on the fact that the interindividual neuroanatomical variability cannot be neglected. We simulated the effect of this inaccurate targeting on the electromagnetic and neurophysiological response to TMS by displacing the stimulation coil to more rostral or dorsal areas with respect to the correct reference position. The induced electric field distribution in the brain and the spatio-temporal distribution of the membrane potentials along a traced nerve bundle, localized in the targeted brain region of interest, are computed. Our results show that the number of spikes initiated and propagating towards deeper limbic regions is highly variable, even for coil shifts of only 2 mm whereas the electric field changes are moderate. Moreover, they illustrate the increased (decreased) generation of spikes in case of targeting more dorsal (rostral) regions. This confirms that an accurate patient-specific determination of the stimulation target in combination with a neuronavigation system is mandatory to perform reliable TMS studies.
