KATHERINE COLE: American researchers are urging athletes to take head injuries seriously. Their comments come after tests showed that a football player suffered serious brain damage from repeated blows to the head. Chris Henry played five years with the Cincinnati Bengals of the National Football League. He died last December when he either fell or jumped from a truck.
Researchers reported in June that Chris Henry had a serious kind of brain damage. It is called chronic traumatic encephalopathy, or C-T-E.
Doctors believe that each hit to the head causes a harmful protein to build up in the brain. This causes the inside of neurons to become tangled together, similar to what doctors find in patients with Alzheimer’s disease. Other studies have linked C-T-E to dementia, depression and memory loss. The condition also is sometimes linked to drug and alcohol use.
