Could a 5-Day brain stimulation blitz ease depression in PTSD?
NCT ID NCT07682207
First seen Jul 02, 2026 · Last updated Sep 18, 2026 · Updated 1 time
Summary
This pilot study tests whether a faster schedule of non-invasive magnetic brain stimulation, called accelerated intermittent theta burst stimulation (iTBS), is practical and safe for adults with both PTSD and major depression. Participants receive six short sessions per day for five days. The study focuses on feasibility, tolerability, and changes in symptoms and brain activity over 12 weeks.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- accelerated intermittent theta burst stimulation (iTBS)
- What this could lead to
- If this faster schedule proves practical and safe, it could offer a quicker, non-invasive treatment option for depression in people with PTSD.
- What could go wrong
- This is a very small, early feasibility study with only 16 participants. It is not designed to prove effectiveness, and results may not apply to everyone. Side effects like headache or discomfort are possible.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Adults aged 18 years or older. * Current post-traumatic stress disorder (PTSD) and current major depressive disorder (MDD), confirmed by a structured diagnostic interview (e.g., MINI 6.0 using the PTSD and MDD modules). * Minimum symptom severity at baseline: HAMD-17 score ≥14 (moderate depression) and/or PCL-5 score ≥33 (probable PTSD). * On a stable pharmacologic and/or psychotherapeutic regimen for at least 4 weeks prior to baseline, and willing to maintain stability during the treatment phase, unless medically necessary. * Capacity to provide informed consent and comply with study procedures and visits at St. Joseph's Health Care, London/Parkwood Institute. * Sufficient English proficiency to complete consent and study assessments. Exclusion Criteria: * Neurologic or device-related risks, including seizure history, traumatic brain injury with loss of consciousness greater than 5 minutes, major neurologic illness, or metal/electronic implants contraindicated for transcranial magnetic stimulation. * Psychiatric or substance-related risks, including current psychotic disorder, acute mania, diagnosis of Bipolar I or Bipolar II disorder, recent substance use disorder, or imminent suicide risk. * Medical or medication-related risks, including unstable severe illness, high-risk medications, hearing impairment, unwillingness to use ear protection, or prior non-response to an adequate course of theta burst stimulation for the current depression/PTSD episode. * Enrollment in another interventional trial. * Inability to comply with the study schedule.
