Keywords: Traumatic brain injury, Diffusion/other diffusion imaging techniquesDiffusion tensor image analysis along the perivascular space (DTI-ALPS) as a non-invasive method for evaluating the activity of the glymphatic system in human brain by using diffusion images. In this study, DTI-ALPS was used to evaluate the activity of the human lymphatic system in patients with Sports-related concussion (SRC). We found SRC has a higher ALPS index compared to the healthy controls. Our findings suggested that abnormal glymphatic function in brain might be a potential biomarker for explaining the cognitive function decline of SRC.
