When a brain-damaged person seems unresponsive, the uncertainty is excruciating. Is the person in a vegetative state, awake but not conscious, or are they minimally conscious, still retaining some shreds of awareness? Scientists can now distinguish between people in vegetative and minimally conscious states by measuring brain waves, a Belgian research team announced at the Society for Neuroscience conference last week, which could lead to a more clear-cut, objective way to make the diagnosis.
The last NFL season was dominated by worries about concussions and other head injuries more than any before, but it ended on an upbeat note when Green Bay Packers quarterback Aaron Rodgers shook off two regular season concussions to win Super Bowl MVP honors. But after the bright lights go down, the long-term effects of brain injuries linger in the dark. And no one, it seems, knew that better than Dave Duerson.
Duerson played 11 seasons as a battering ram, a safety for the Chicago Bears and New York Giants. Last week he committed suicide, thrusting the worries about the long-term consequences of repeated blows to the head back into the spotlight.

According to reports, Duerson made sure to get his final message across. He texted family members on the day of his death that he wanted his brain to go to the center, and to be sure he was heard, he left behind a paper note reading “Please, see that my brain is given to the NFL’s brain bank.”
