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.
