Brain Connectivity and Behaviour in Post-Concussion Syndrome: A Scoping Review Protocol

Background: About 10-15% of patients experience persistent symptoms 3-months post-concussion, referred to as Post-Concussion Syndrome (PCS). There are no biomarkers for detecting this condition, but advanced neuroimaging tools such as Diffusion Tensor/Weighted Imaging (DTI/DWI) or functional MRI (fMRI) can detect subtle changes in the integrity of white matter tracts or brain activity, respectively. Methods This study protocol presents search strategies for a scoping review that provides an overview of the studies that assessed both alterations of structural and/or functional connectivity and cognitive/neuropsychiatric outcomes in PCS. Discussion A better understanding of the brain-behaviour relationships in PCS can lead to improved diagnosis of this condition. Scoping Review Protocol Registration: osf.io/sqt7d
