Study: Brain scans may identify concussion-related disease
NEW YORK - A brain-scanning technique might one day help identify people with a disease linked to concussions in football and other sports.
The illness, called CTE, is now diagnosed only after death.
In a new study, scans of retired football players showed deposits of abnormal protein in a pattern like what shows up at autopsy.
CTE causes progressive brain degeneration in athletes and others who've had repeated concussions and other blows to the head. Symptoms include memory loss and progressive dementia.
No cure is known. But the brain-scanning approach raises the possibility of detecting the disease early on, when the chances would be greatest for success of experimental treatments, study authors said.
The study was released Monday by the Proceedings of the National Academy of Science.
