A single incidence of traumatic brain injury (TBI) can lead to long-lasting neurodegeneration, according to a study of 32 individuals. In addition to clarifying the little-understood chronic effects of TBI, the study's methods could improve the diagnosis and monitoring of brain damage in patients who have suffered an injury. Research has shown that TBI can trigger progressive accumulation of tau, a protein associated with neurodegeneration that plays a major role in Alzheimer's disease.
