Accelerated iTBS for PTSD and Depression
Accelerated Intermittent Theta Burst Stimulation for Depression in Post-Traumatic Stress Disorder: A Single-Arm, Open-Label Feasibility Study
The goal of this pilot clinical trial is to learn if a faster brain stimulation schedule is practical, safe, tolerable, and acceptable. This study looks at accelerated intermittent theta burst stimulation, or accelerated iTBS. This is a non-invasive type of magnetic brain stimulation. This study is for adults with post-traumatic stress disorder (PTSD) and major depressive disorder (MDD).
The main questions this study aims to answer are:
- Can participants complete six short brain stimulation sessions per day for five days?
- Is this treatment schedule safe and tolerable for participants?
- What changes occur in depression symptoms, PTSD symptoms, anxiety, quality of life, and brain activity over time?
Participants will:
- Complete health screening and baseline assessments.
- Receive six short sessions of magnetic brain stimulation per day for five days.
- Have their brain activity measured using an EEG recording.
- Return for a post-treatment assessment at Week 2 and follow-up visits at Week 5 and Week 12.

Beskrivelse
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.

- 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.

Eksperimentel: Accelerated iTBS
Participants will receive active accelerated intermittent theta burst stimulation (iTBS).
Treatment will consist of six short stimulation sessions per day delivered over five consecutive days, for a total of 30 sessions.
|
Accelerated intermittent theta burst stimulation, also called accelerated iTBS, is a non-invasive magnetic brain stimulation intervention.
Stimulation is delivered to the left dorsolateral prefrontal cortex using a transcranial magnetic stimulation system.
Participants receive six short sessions per day over five consecutive days.
