Summary

This study is testing a personalized form of brain stimulation called PrTMS as a treatment for post-traumatic stress disorder (PTSD) in military service members and veterans. Unlike standard approaches, this treatment uses a simple brainwave test (EEG) to tailor the therapy to each individual. Participants will be randomly assigned to receive either active treatment or a comparison (sham) treatment over 6 weeks. Researchers will track changes in PTSD symptoms, mood, sleep, and overall well-being, including using wearable devices to measure things like sleep and heart rate. The goal is to see whether this personalized approach can provide greater and longer-lasting relief for individuals living with PTSD.

Detailed description

This study is a randomized, double-blind, sham-controlled trial evaluating a personalized approach to repetitive transcranial magnetic stimulation (PrTMS) for the treatment of post-traumatic stress disorder (PTSD) in military service members and veterans. PrTMS integrates spectral electroencephalography (sEEG) with neurocognitive assessments to individualize stimulation parameters, including frequency and intensity, and to allow for dynamic adjustment over the course of treatment based on each participant's evolving neurophysiological profile. Participants will undergo a 6-week treatment protocol (5 sessions per week), followed by longitudinal assessments over 6 months to evaluate durability of response. Multimodal outcomes will include clinician-administered and self-report measures of PTSD, mood, anxiety, and sleep, as well as physiologic and behavioral data collected via wearable devices. This study is designed to determine whether EEG-guided, precision neuromodulation improves clinical outcomes compared to standard, non-personalized stimulation approaches and to inform the development of individualized treatment strategies in PTSD.

Conditions

• Posttraumatic Stress Disorder (PTSD)

Interventions

Type	Name	Description
DEVICE	Transcranial Magnetic Stimulation	Personalized repetitive transcranial magnetic stimulation (PrTMS) is delivered using the Neurocare Apollo TMS Therapy System for 30 minutes per session, 5 days per week, over 6 weeks. Stimulation parameters (frequency 8-13 Hz and intensity typically 50-60% of motor threshold) are individualized based on baseline and serial spectral EEG (sEEG) assessments, with adjustments made throughout treatment to optimize response.
DEVICE	Transcranial Magnetic Stimulation Sham	Sham stimulation will be delivered using the same Neurocare Apollo TMS Therapy System as the active intervention, with identical treatment schedule (5 days per week for 6 weeks; 30 minutes per session). A sham coil identical in appearance to the active coil will be used, which does not generate a therapeutic magnetic field. To mimic the sensory experience of active treatment, the sham procedure will produce similar auditory clicking and will include a surface electrical stimulation (TENS) applied to the forehead to replicate scalp sensations and mild muscle contraction. This approach is designed to maintain blinding while delivering no active neuromodulatory effect.
