The latest concussion study at the Boston University School of Medicine, released in January, looked at the donated brains of 85 people who had suffered head trauma in football, hockey, boxing or military combat. The study found 68 had evidence of chronic traumatic encephalopathy, the degenerative brain disease also found in Seau's brain after the popular player shot himself in May.
"This success comes at a price to the players who make the game great," Seau's parents said in their lawsuit, which was consolidated with the other Brody cases last month.
