Importantly, DNALI1 expression was significantly correlated with AT8 (Figure S4a, Supporting Information, r = 0.53, p = 0.011) and the ratio of ptau181/tau (Figure S4b, Supporting Information, r = 0.68, p = 0.002) in participants with TBI‐“clinical dementia”, whereas such correlations were absent in “non‐demented” participants. Here, DNALI1 is linked to dementia.
