Study summary

This study will investigate the anti-anhedonic efficacy of a novel neurostimulation strategy termed accelerated intermittent theta burst stimulation (aiTBS) in participants with treatment resistant depression (TRD).

Read the detailed description

Repetitive transcranial magnetic stimulation (rTMS) is an established therapy for treatment-resistant depression. The approved method for treatment is 10Hz stimulation for 40 min over the left dorsolateral prefrontal cortex (L-DLPFC). This methodology has been effective in real world situations. The limitations of this approach include the duration of the treatment (approximately 40 minutes per treatment session, 5 days per week, for 4-8 weeks). Recently, the investigators have pursued modifying the treatment parameters to reduce treatment times with an accelerated treatment paradigm. This study aims to further study the accelerated protocol and examine changes in neuroimaging biomarkers.

Interventions

  • DeviceActive TBS-DLPFC

    Participants in the active stimulation group will receive intermittent TBS to left DLPFC. The L-DLPFC will be targeted utilizing the Localite neuronavigation system. Stimulation intensity will be standardized at 90% of RMT and adjusted to the skull to cortical surface distance (see Nahas 2004). Stimulation will be delivered to the L-DLPFC using a MagPro TMS system (MagVenture, Denmark).

  • DeviceActive TBS-DMPFC

    Participants in the active stimulation group will receive intermittent TBS to DMPFC. The DMPFC will be targeted utilizing the Localite neuronavigation system. Stimulation intensity will be standardized at 90% of RMT and adjusted to the skull to cortical surface distance (see Nahas 2004). Stimulation will be delivered to the DMPFC using a MagPro TMS system (MagVenture, Denmark).

  • DeviceSham TBS-DLPFC or DMPFC

    The parameters in the sham arm will be as above with the internal randomization of the device internally switching to sham in a blinded fashion.

What researchers measure

Primary outcomes

  1. Percentage Change in MADRS Score

    The Montgomery-Asberg Depression Rating Scale (MADRS) is a 10-item self-survey administered scale, designed to be particularly sensitive to antidepressant treatment effects in patients with major depression. Score range: 0 to 54, higher scores correspond to more severe depressive symptoms.

    Time frame: Baseline, immediate post treatment (up to 2 weeks post baseline), 4 weeks and 8 weeks post treatment.

  2. Percentage Change in SHAPS Score

    The Snaith-Hamilton Pleasure Scale is a 14-item self-report questionnaire designed to measure the reduced ability to experience pleasure. Score range: 0 to 14, higher scores indicate higher levels of anhedonia.

    Time frame: Baseline, immediate post treatment (up to 2 weeks post baseline), 4 week and 8 week post treatment.
