Abstract

Is tau load associated with long-term outcomes of TBI? By using PET to assess tau deposits in patients with chronic TBI, Takahata et al. reveal elevated tau load compared to age-matched controls, and show that the abundance of tau in white matter is associated with late-onset neuropsychiatric symptoms.
