New Imaging Method for Early Detection of Traumatic Brain Injury

  Five retired profesional football players age 45 and older with a history of concussions underwent PET scanning after IV injections of FDNNP, a chemical marker which binds to amyloid beta and tau .
  Compared with healthy males, the former pro athletes had elevated levels of FDNNP in the amygdala and subcortical regions of their brains.
  Additionally, higher levels of FDNNP correlated with a higher number of reported concussions.
