Suicide was linked to head injuries suffered on the field. Todays report identifies brain abnormalities consistent with what is known as chronicti traumatic encephalopathy, or cte, which is caused by repetitive trauma to the brain. Dr. Russell lonzer oversaw the study. Individuals that have been found to have cte in the past, in some cases, have exhibited behaviors such as impulsivity, irritability, aggression, memory loss, and suicidal thoughts. Reporter seau is the fifth former nfl player to commit suicide who was later found to have cte. More than 4,000 players have filed suit against the nfl for brainrelated injuries. The nfl has changed rules to discourage blows to the head. It has given a 30 Million Research grant to the National Institutes of health to study medical conditions prominent in athletes. Y we need to better understand this. Nditio we need to have better awareness, better diagnostic capabilities. We need to find ways to assess this before someone passes away, or diagnose it. Reporter seaus familyay released a statement saying thatd they were deeply saddened that he suffered from such a debilitating condition. And scott, the nfl said the findings underscore the need forfi Additional Research to better understand cte. Pelley seth, thank you. There was another School Shooting today this time, at a high school in taft, california, just over 100 miles north of los angeles. The sheriff says a Student Armed with a shotgun shot one classmate, leaving him critically wounded. A teacher talked the shooter into putting the gun down. This happened on the very day that the Vice President met with the n. R. A. The Vice President has been tasked with coming up withga recommendations for curbing gun violence, and Major Garrett is at the white house for us tonight. Major . Scott, there were no illusions on either side about what would come from the vices president s meeting with the National Rifle association and other gun rights groups. Re but for pure political andso Public Relations reasons neither side could ignore the other. They didnt, and deep differences remain. The meeting lasted more than 90 minutes. Afterward, we spoke with n. R. A. President david keene, who did not attend the session with biden. He described the conversation asescr onesided. We were disappointed, in a sense, because prior to the meeting, they made a number of statements from the white house that they havent made up their mind. But at the meeting, the Vice President made it clear that, in terms of firearms, they have made up their mind. Reporter keene said the n. R. A. Will take its lobbying might and growing membership list to congress to fight every item on the biden agenda, from a reinstated assault weapons banve to a universal criminal and Mental Health background check and bans on highcapacity ammunition magazines. The group also opposes increased federal research into gun violence, another biden priority. I think there are a lot of people who would like to completely gut the Second Amendment and to deprive americans of the rights that they enjoy under the Second Amendment. Are they going to be able to do that . I dont think so. Reporter in a separate meeting with hunters and conservation groups, mr. Biden appealed for consensus. Even if what we do only saves one life, it makes sense. And i think we can do a great deal without in any way imposing on or impinging on the rights of the Second Amendment. That the Second Amendment guarantees. Reporter n. R. A. Says it knows, after newtown, theyre facing a gun control debate unlike any in its history. And they may be more politically isolated than they were in 1994, when the assault weapons ban was first pushed tenaciously through congress by thensenator joeth biden. Pelley major, thank you. Major just mentioned the n. R. A. s growing membership. Well, the n. R. A. Told us today that it has attracted 100,000 new members since the newtown tragedy for a total membership today of 4. 2 million members. President obama today introduced his nominee for treasury secretary, white house chief of staff jack lew. The president said lew is a master of policy who can work with members of both parties. And about lews now famous signature, which would appear on the bills in your pocket, the president said that lew has promised him to make at least one letter legible in order to not debase our currency, the president said. The president is getting some criticism today for not naming more women to his cabinet. And after this white house photograph appeared in the newspaper, showing the president th meeting with top aides, all but one of them men, the white house quickly put out another photograph of the president with senior advisors, including three women. With a little perspective on the president s cabinet picks, we turn to our political director john dickerson. John, what do you make of it . Reporter well, scott, there are a series of critiques here. Some of the president s political allies think that he should acknowledge in his staff selections that he won reelection with the votes of women and minorities. Other critics have pointed out that these all white male selections at the important departments of state, defense,s and treasury suggest a lack of diverse viewpoints in the second term. And yet another criticism is that these posts, which are in the news almost daily, send ais bad signal about what is possible for anyone who is not already in the white male club. The president won reelection, in part, by relentlesslyhe pressing mitt romney and republicans on every aspect of gender and race issues. Hes now getting to experience what thats like. Pelley john, the president did prefer susan rice as an appointment for. As the appointee for secretary of state to replace hillary clinton, butans the republicans didnt allow him to go forward with that. Reporter well, thats right. It and white house aides point right to that. Susan rice was on the short list to be secretary of state until she withdrew her name from nomination. And immediately, aides said, that put her on the short list someday to be national securitye advisor. That is a top job. She, of course, remains in the cabinet, as do several other women and minorities. The president s closest, and some would say most powerful advisor, is a woman, an African American woman, valerie jarrett, and white house aides point out that the white house has more women than men. They also say stay tuned, the president has more personnel decisions to announce. Pelley john, thanks very much.

The government said today that the recommended dose for women should be cut in half, and a lower dose is recommended for men as well. Dr. John lapook has been looking into this for us. Well, scott, the active ingredient in ambien, the fda decision comes from lab studies that show, eight hours after somebody takes a normal standard dose of ambien, the drug levels in the blood are potentially capable of causing a driving problem in 15 of women and 3 of men. Its even higher in the extended form of the drug thats 33 of women and 25 of men. Pelley eight hours afterwards. Eight hours later. Pelley there are other sleep medications on the market.

Because bashar assad destroyed all of syria and we come here to have a life, good life. Reporter another boy, ali, told us that he lost both of his hands and his left eye when a plane bombed his house. In a math class, we wanted to know how many have lost someone in their family in the war. Nearly a third raised their hands. Principal zikwan dayid taught history in syria. He told us he was arrested threeus times by Government Forces before he fled to turkey. He said many of the children here are traumatized. They get frightened by loudes noises, he told us.

Textbooks are donated by a charity and the teachers salaries are minimal. What is your dream for these children .

Clarissa ward is joining us on the border with turkey and syria. Clarissa, what is the refugee situation there now . Reporter well, its incredibly difficult, scott. The turkish government is really struggling to house this wave of refugees. They say that theyve spent a billion dollars on trying to host them. There are currently more than 150,000 Syrian Refugees living here. But they simply cant build these camps quickly enough. And one result that you are starting to see because of that is that there are now tens of thousands of syrian wouldbe refugees who are massing along the turkish border, but still stuck inside syria where that aid cannot reach them easily.
