A study hints that it might be possible to diagnose chronic traumatic encephalopathy, a neurodegenerative disease associated with frequent head injuries, while patients are still living.

People who have suffered traumatic brain injury had slower reaction times and more false starts after disrupted sleep than well-rested controls, according to a study presented at the Society for Neuroscience meeting.

Levels of tau, amyloid-β 42, and IL-10 extracted from extracellular vesicles that started out in the brain were higher in military personal suffering head injuries compared with healthy soldiers.

The diagnostic measures two proteins indicative of brain injury.

MRI scans and other assessments of high school football players reveal changes in brain tissue, correlated to head impacts, after just one season, researchers report.

A Congressional investigation indicates that the National Football League may have sought to steer millions of dollars in National Institutes of Health funding away from one of its critics.
