Chicago: Football players with memory and behavior problems have no way of knowing for sure if getting hit too many times caused brain damage. The only test to diagnose their condition is done after death in an autopsy.But now, researchers are experimenting with an imaging technique to detect a debilitating condition caused by repeated concussions. And a study in Boston of five retired athletes — three NFL players, a boxer and a wrestler — is being called a preliminary first step toward diagnosis and maybe even treatment.
"It tells us that these guys with repetitive head injury do have something that is biochemically abnormal," Lin said.There were no "before and after" images of the athletes` brains, and the research doesn`t prove that repeated head blows caused the damage. But it provides intriguing evidence that needs to be confirmed in additional research, said Dr. Jeffrey Kutcher, chief director of a neurological sports injury program at the University of Michigan."It`s an important step," said Kutcher, who was not involved in the study.Currently, chronic traumatic encephalopathy or CTE is diagnosed by pathologists inspecting brain tissue during autopsies.There is no treatment for the condition. But if it turns out that chemical changes in the brain are a true symptom, then scientists could test drugs that would affect those chemicals to see if that slows or prevents symptoms."The only way we can get to the point of studying potential treatments is to be able to diagnose it during life," said Robert Stern, a study co-author and a director of the Boston University center studying CTE. Several former NFL players have agreed to donate their brains after death for the research.If the new imaging proves to be an accurate detection method, then the technique could potentially help determine whether athletes with head injuries can return to sports or should stop playing for good, said Dr. Stefan Bluml, director of an imaging technology lab at Childrens Hospital Los Angeles.Bureau Report
