Detailed Description
Repetitive transcranial magnetic stimulation (rTMS) is an established technology as 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 very successful. The limitations of this approach include the duration of the treatment (approximately 40 minutes per treatment session). Recently, researchers have aggressively pursued modifying the treatment parameters to reduce treatment times with some preliminary success. This study will investigate the efficacy of a further modified protocol, creating a more rapid form of the treatment and look at the change in neuroimaging biomarkers. In particular, this study will determine the efficacy of re-treatment in individuals who have already experienced benefit of the accelerated protocol to ensure results can be repeated.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Accelerated theta burst treatment All participants will receive theta-burst TMS. |
Device: Intermittent theta-burst stimulation (iTBS)
Participants will receive iTBS to the left DLPFC or bilateral DLPFC, to the right and left DLPFC. The DLPFC will be targeted utilizing either Localite's neuronavigation system or Nexstim's eField 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 or bilateral DLPFC using either a MagVenture MagPro X100 or a Nexstim TMS device.

Outcome Measures
Primary Outcome Measures
- Percentage change in Hamilton Depression Rating Scale 21-Item score [Difference between baseline and one month after aiTBS treatment]
A 21 item clinical assessment tool used to rate a patient's level of depression
Secondary Outcome Measures
- Change in Hamilton Rating Scale for Depression (HAMD-17) [Pretreatment, immediately posttreatment, 2 weeks posttreatment, 4 weeks posttreatment]
A provider administered questionnaire used to assess remission and recovery from depression.
- Change in The Scale for Suicide Ideation [Pretreatment, immediately posttreatment, 2 weeks posttreatment, 4 weeks posttreatment]
A rating scale that measures the current intensity of specific attitudes, behaviors, and plans to commit suicide
- Change in Hamilton Rating Scale for Depression (HAMD-6) [Every day of stimulation, follow-up every 2 weeks after treatment for 6 months by telephone]]
A 6 item questionnaire used to score the severity of depression.
- Change from baseline functional connectivity [Pretreatment, immediately post-treatment, 4 weeks post-treatment]
We will assess functional connectivity as seen on resting state fMRI, between the subcallosal cingulate to the default mode network and within the default mode network.
- Change in Beck Depression Inventory (BDI) [Pretreatment, immediately post-treatment, 4 weeks post-treatment]
Self-report measure of depressive symptoms
- Change in Montgomery-Åsberg Depression Rating Scale (MADRS) [Pretreatment, immediately post-treatment, 4 weeks post-treatment]
A 10 item clinician rated measure of depressive symptoms
