Demographic features and neuropathology features including National Institute on Aging–Alzheimer’s association guidelines ‘ABC’ scores of the cases studied. Chronic traumatic encephalopathy cases also include frequency of traumatic incidents (first figure frequency of reported concussions, second figure concussions resulting in loss of consciousness) and sporting career length
