(KTVI) – The NFL recently agreed to pay 4,000 former players $765-million in a class action suit because of the affect suffered from concussions.

And now, a new study is adding to the evidence that the repeated blows to the head may leave long lasting effects in athletes.

Dr. David Brody, Site Director of the NFL Neurological Care Unit at Washington University, came by the studio to share his insight on the new findings.

The study looked at a group of former NFL players and their brain activity.

Researchers found a major difference when NFL player’s brains were compared with brain activity of non NFL players.

Dr. Brody talked about what concussions may mean later on in life and how these injuries impact players differently at varying ages.
