How iTBS and a brain drug could boost brain wiring to help depression
Official title: Synaptic Mechanisms of Intermittent Theta Burst Stimulation for Major Depressive Disorder
Funded at Mclean Hospital · NIH-11337250 · Data updated 2026-11-12
A study tests whether a brain-stimulating treatment (iTBS) works by improving brain plasticity and whether adding a drug (DCS) enhances this effect for people with major depressive disorder.

Who could benefit from this research
✓Could help
Adults diagnosed with major depressive disorder who are candidates for iTBS and may consent to participate in a pharmacologic augmentation study.
✕Less likely to help
Some participants may not experience symptom improvement or may have limited or no enhancement of brain plasticity.
What this research studies
This project looks at how a specific brain stimulation technique called intermittent theta burst stimulation may improve the brain’s ability to change and adapt, which is often reduced in people with depression. It also tests whether a medication that acts on NMDA receptors, d-cycloserine, can boost the benefits of iTBS. Researchers plan to measure changes in brain plasticity and relate them to clinical symptoms in participants who receive the treatment in a clinical setting. The study combines clinical depression treatment with neuroscience methods to better understand how these interventions work together. The goal is to guide future optimization of plasticity-inducing therapies for depression and possibly other disorders.
Why it matters
Potential benefit: If successful, the study could lead to more effective depression treatments by enhancing brain plasticity.
How similar studies have gone: Preliminary data suggest NMDA receptor modulation can influence TMS-related plasticity and clinical symptoms, but this approach needs direct clinical validation in depression.
