[Cuomo:] All right. We got results from the largest study ever about TBI, traumatic brain injury, and football, and the link is stronger than ever to this degenerative disease called CTE. Andy Scholes has more in "The Bleacher Report." We know that Sanjay Gupta looked at this, but this research from Boston University, this is more than guys like us expected to learn, Andy.
[Andy Scholes, Cnn Sports Correspondent:] Yes, that's right, Chris. I mean, it's definitely concerning for the game of football. Researchers at Boston University studied the donated brains of 111 deceased former NFL players, and they found that 110 of them were found to have a degenerative brain disease CTE. That's more than 99 percent. In total, CTE was diagnosed in 87 percent of 2002 former football players studied, that included high school and college players. Now, CTE is believed to be caused by repeated trauma to the head. It can only be diagnosed in someone after death. Now, it's important to note that in this study, many of the donated brains came from former players and their families who were worried about CTE while the player was still alive. Lead author of the study said there are many questions that remain unanswered like how common is this and how many years of football are too many. Now, the NFL issued a statement saying these studies are important for advancing science related to head trauma and the league will continue to work with a wide range of experts to improve health of current and former NFL athletes Alisyn.
[Camerota:] That is really valuable that they're beginning to look at all this and try to get some answers. Andy, thank you very much. So what drives President Trump's tweets? Well, we're going to look at his social media habit and the patterns it reveals and what all that tells us, next.
