More than half of the first 21 brains donated to the Australian Sports Brain Bank by former athletes showed signs of chronic traumatic encephalopathy (CTE), a degenerative disease caused by repeated concussions, a study showed.

Abbot received 510(k) clearance for the first rapid handheld traumatic brain injury (TBI) blood test, which will help clinicians assess individuals with suspected mild TBIs, including concussions.

Dr. Ann McKee of Boston University studies the brains of deceased football players at the world’s largest brain bank, hoping to learn about the long-term impact of repeated head traumas for people ranging from professional athletes to victims of domestic abuse.

A study of more than a thousand former professional soccer players has uncovered significantly more deaths from brain disease than among non-players.

One of the largest concussion studies ever conducted found that a new blood test developed by Abbott was able to detect a protein in the blood that confirmed a concussion, even if the result of a CT scan came back negative.

Levels of a protein called tau in spinal fluid may help predict which former pro athletes with multiple concussions will end up with long lasting effects from their history of jolts to the brain, a new study suggests.

Abbott announced the next phase of partnership with the U.S. Department of Defense and researchers from the Transforming Research and Clinical Knowledge in Traumatic Brain Injury (TRACK-TBI) Network, one of the largest traumatic brain injury efforts of its kind.

For soccer players, regularly “heading” the ball may have a bigger effect on everyday cognitive functioning than occasional accidental head impacts, a U.S. study suggests.

Nearly 20 percent of American adolescents, or one in five, has suffered a concussion, according to newly released statistics.

NFL teams violated federal laws governing prescription drugs, according to a Washington Post story based on sealed court documents contained in a federal lawsuit filed by former players against the league and reviewed by the newspaper.
