Much attention has focused on the neurodegenerative syndrome called chronic traumatic encephalopathy (CTE), which is associated with a history of repeated concussive (mild TBI) and/or subconcussive brain trauma (Bailes, Petraglia, Omalu, Nauman, & Talavage, 2013) and defined by the “accumulation of abnormal hyperphosphorylated tau (p‐tau) in neurons and astroglia distributed around small blood vessels” (McKee et al., 2016). The gene discussed is MAPT; the disease is brain injury.
