There has been a lot of talk about football and concussions in players, but new research suggests that brain changes can occur in high school football players when less severe head injuries occur.

The study found that repeated blows to the head after just one season could cause significant changes in the brain, even if there is no concussion.

The more often the players were struck, the more evidence they showed of brain changes that appeared abnormal.

Traumatic head injury

Amyotrophic lateral sclerosis has been all over social media lately with the all familiar ice bucket challenge. The attention A.L.S. is getting from the challenge has raised the debate of whether or not contact sports of vigorous exercise might somehow contribute to the development of the fatal disease.

When 4,500 retired players filed a lawsuit after they said the league hid the long-term impact of concussion, the NFL agreed to a $765 million settlement. However, only players with the most severe brain injuries would be eligible to collect, and the estates of the retirees who died before 2006 would be excluded, according to a draft of the proposed settlement sent on October 9 to players represented by one of the law firms that sued the NFL.

New York Attorney General, Eric T. Scheiderman warned Thursday, that claims by equipment makers of helmets that boast “anti-concussive” properties cannot be relied upon – especially by parents of children who play the game. Any claims made that a helmet is made to be “anti-concussive” or “concussion-proof” is misleading and a potentially dangerous claim which gives parents a false sense of security.

A new study, conducted by researchers from the Virginia Tech-Wake Forest School of Biomedical Engineering and Sciences, challenges the belief that more practice will help reduce the risk of concussions in football players. Our current assumption is that more practice means better game performance and therefore, less head injuries during a game.

New research has found that the heavier and more expensive football helmet sold today does not lower the risk concussions any more than the standard helmet does. A study that monitored more than 1,300 football players at 36 different Wisconsin high schools found that players who wore older and more worn out helmets received just as must protection as the players with the newer and more expensive helmets. About 40,000 high school students in the United States receive concussions ever year.
