The TBI group had a significantly greater burden of ePVS (prevalence ratio rate (PRR) = 1.29, p = 0.013, CI95% [1.05, 1.57]). The presence of bilateral lesions was associated with greater ePVS burden (PRR = 1.41, p = 0.021, CI95% [1.05, 1.90]). There was no association between ePVS burden, sleep quality (PRR = 1.01, p = 0.491, CI95% [0.98, 1.048]) and sleep duration (PRR = 1.03, p = 0.556, CI95% [0.92, 1.16]). ePVS was associated with verbal memory (β = -0.42, p = 0.006, CI95% [-0.72, -0.12]), but not with other cognitive domains. Burden of ePVS was not associated with emotional distress (β = -0.70, p = 0.461, CI95% [-2.57, 1.17) or brain age (PRR = 1.00, p = 0.665, CI95% [0.99, 1.02]).Discussion TBI is associated with a greater burden of ePVS, especially when there have been bilateral brain lesions. ePVS was associated with reduced verbal memory performance. ePVS may indicate ongoing impairments in glymphatic system function in the chronic post-injury period. %U //www.ez-admanager.com/content/neurology/early/2023/05/08/WNL.0000000000207370.full.pdf
