- A new study from Boston University found that concussions do not lead to chronic traumatic encephalopathy, or CTE, a neurodegenerative disease that causes dementia.

To further understand this phenomenon, the researchers had to resort to mouse brain models.

Let's start with the obvious: Four teenaged brains and some mice can't support sweeping conclusions about the causes of CTE. The athletes died 1, 2, 10 and 128 days, respectively, after sustaining their injuries. "The results may explain why approximately 20 percent of athletes with CTE never suffered a diagnosed concussion".

They found early evidence inside the brain consistent with signs of CTE, including abnormal accumulation of tau protein.

An earlier study out of BU found CTE in 110 of the 111 brains donated from National Football League players. "These results were surprising and alarming", says Dr.

"It's the hits to the head, not concussion, that trigger CTE", says Lee Goldstein, associate professor of psychiatry at the School of Medicine and a co-author of the study.

In fact, just the act of being hit is the mechanism that triggers CTE, which could potentially be a death knell for the long-term viability of football as we know it.

We're hearing a lot more about concussions and their long term effects on the brain, but a new study found there's also cause for concern about other blows to the head.

Those blood vessels can become leaky which leads to the cascade of changes in the brain that cause CTE.

"We were able to pick up the type of damage that we saw in the brain and now pick it up in the living animal and this is very helpful as we try to move this into the clinic to try to detect early fingerprints of the disease", Goldstein said. "Concussions can not be the cause of CTE". There have been studies earlier that show that CTE has occurred without the signs of a concussion.

The NFL has been working overtime to make us all believe that its newfound supposed fervor for protecting players from getting concussions and playing through them will be a boon for the future of its players, and the game itself.

This study provides the "best evidence we have so far", he added, that it's really those subconcussive impacts (those below the threshold of an actually concussion) that are risky and cause CTE.

The research was presented in New York City in conjunction with a new campaign from the Concussion Legacy Foundation to discourage the participation of kids under 14 in tackle football.
