Clinical Trial Summary

The current study aims to better understand the efficacy of intermittent theta-burst stimulation (iTBS) treatment in patients diagnosed with post-concussion syndrome (PCS) and to explore changes in brain networks after undergoing iTBS to assess its safety and feasibility in treating PCS.


Clinical Trial Description

This open-label pilot study aims to investigate the potential of a non-invasive brain stimulation technique, accelerated intermittent theta-burst stimulation (iTBS) repetitive transcranial magnetic stimulation (rTMS), for treating post- concussive syndrome (PCS) in persons with mild traumatic brain injury (mTBI). PCS is characterized by symptoms like cognitive impairment, mood dysregulation, fatigue, and headaches, with limited treatment options. Previous research has indicated brain network dysfunction in mTBI patients and suggested the potential of conventional once daily high frequency rTMS for treating PCS symptoms. Our proposal builds on these findings by utilizing the expertise and resources of Sunnybrook's Harquail Centre for Neuromodulation, which has extensive experience in delivering rTMS and theta-burst stimulation for treatment-resistant depression. This pilot study will implement an accelerated iTBS rTMS protocol, offering shorter treatment duration, as well as MRI-guided stimulation for precise targeting. The investigators will also explore changes in brain function following rTMS using a technique called functional magnetic resonance imaging. The investigators ultimately aim to understand how iTBS may alter the post-concussive brain and the extent to which these changes may improve PCS. ;
