86yearold Andre Cassagnes passed away. He created the classic drawing toy in his garage in 1950. It made its debut in 1959. We told you last week it was so cold that officials in one new jersey town postponed a polar bear plunge. The event where swimmers go in a dip in fridged for fun. The water temperature a balmy 42. More top stories when cnn sunday morning continues. Good morning, thanks for joining us. Just about ten hours now until the super bowl. You know, i love football and im looking forward to the game tonight. This year im also going to be thinking harder about all those collisions as i watch them and how they affect the health of players now and potentially for years to come. The most pressing questions i see are about lasting damage from hard hits to the head. There is this new study out of ucla and it has relevance for all of us. It may have found a way for for the first time to look for tell tale damage in the brains of players who are still alive. When he was a backup quarterback in the nfl, wain clark was lucky to call a play or throw a pass. In fact, he spent most of his time on the sidelines. So, i didnt take the contacts that other players did. Except for one game, one concussion in 1972. I went down on a slump because i didnt know where i was and didnt know what was going on. He spent several blear hours confused. Somewhere over new mexico or arizona i finally became aware of what was going on, again. Clarks brain was rattled, but only happened once during his fiveyear career. The scans turn red and green and yellow. Reporter that is what makes this picture of clarks brain so interesting and perplexing. Researchers at ucla says he has an abnormal protein in his brain. If it sounds familiar thats because its been found in the brains of several former nfl players. All had serious cognitive and emotional problems and eventually committed suicide and were diagnosed with cte or chronic traumatic encephlopathy. Look over here. Normal brain scan compared to two players in the study who had one concussion. You can immediately tell bright areas of yellow and bright areas of red. Thats what researchers believe indicates the presence of it. Memory problems, depression and anger. Theyre not looking just whether or not its present, but whether its present in parts of the brain that are responsible for those emotions. What were looking at reporter dr. Gary small, the lead researcher, said he was supposed to find it in the brains of all five players in the study. Until now it could only be seen by pathologists after death. What pathologists have been seeing in the brain are little deposits. We could see the same pattern. Reporter small is cautiously optimistic that this brain scan will diagnose cte in living people. Its a small step forward, but a baby step. Reporter robert stern, a cte expert at the Boston University school of medicine is a bit more skeptical. He says smalls brain scan doesnt just measure tow, it measures another protein, which is present in alzheimers disease. We dont know if whats lighting up is the tau protein. Reporter are they suffering from alzheimers . I agree we need to do alzheimers study to pin down our hypothesis is correct. Reporter remember, researchers found tau in his brain, but he is a cogatively normal 65yearold. Whether it necessarily means an early death or other factors like genetics also play a role. Still, clark says hes willing to keep up the brain scans until he dies to help figure it out. Be able to find out what our conditions are now, address possible interventions earlier, so we dont have to wait until were dead and autopsy our brains. I could tell you that players are much more concerned about head injuries than they were even just a few years ago. In fact, i want to take a moment to introduce you to lamar campbell. He took and gave out a lot of hard hits and hes now living with the consequences. Lamar campbell has achieved what many young men only dream of. After four years starting for the university of wisconsin, he made it to the pros. I got offered to come to detroit lion in 1988. I made the team and played with them for five years. Reporter injuries ended his career, but he successfully found a new life after the game. As a real estate broker. Welcome back to life after the game. Reporter and radio talk show host on the voice america sports network. A platform he uses to educate other players about transitioning to life after football and the dangers of injuries you cant really see. Repeated hits to the head. Perception of what a concussion was was different. We didnt think you had a concussion until you were knocked out on the field and we looked at it as a badge of honor. Reporter he didnt know concussions could cause serious injury to the brain. Now he says playing football takes years off a players life. Reporter he also said he suffered some memory loss. Situations where i dont remember certain series. I will be out there and not realize exactly what was going on. Reporter while he was never diagnosed, looking back, campbell believes he had over ten concussions in his football career and he believes players today need to recognize the symptoms and be willing to let their brains heal. A year ago campbell considered donating his brain for research for cte. Its a degenerative brain disorder found in athletes with repetitive brain trauma and most recently linked to the suicides. I wrapped my brain around it for a long time. I think my decision was made, it was just the timing of when to tell my family with everything that was going on, it was such a hot topic and players committing suicide. One thing you didnt want to do was scare your family members. You didnt want them to think you were on the verge of doing something that drastic. Reporter just a few months ago, he sent his paperwork to Boston University. For him, it is all about the game. Watching the super bowl today, i know that seeing those collisions theyll show them in slomo and make me shutter just a bit. Coming up, making fictional medicine as realistic as we can. Exclusive look behind the scenes of my new tnt show monday mornings. I saw his brain. There was nothing you could do. Hey did you know that honey nut cheerios has oats that can help lower cholesterol . And it tastes good . Sure does wow. [ buzz ] delicious, right . Yeah. Its the honey, it makes it taste so. Well, would you look at the time. Whats the rush . Bee happy. Bee healthy. With clusters of flakes and os. Oh, ho ho. Its the honey sweetness. I. I mean, you. Love. [ angry gibberish ] [ justin ] mulligan sir. Mulligan. Take a mulligan. I took something for my sinuses, but i still have this cough. [ male announcer ] truth is, a lot of sinus products dont treat cough. They dont . [ male announcer ] nope, but alka seltzer plus severe sinus does it treats your worst sinus symptoms, plus that annoying cough. [ angry gibberish ] [ fake coughs ] sorry that was my fault sir. [ male announcer ] alka seltzer plus severe sinus. [ breathes deeply ] oh, what a relief it is [ male announcer ] try alka seltzer plus severe sinus day and night for complete relief from your worst sinus symptoms. Ive always been a fan of medical dramas. In some ways like holding up a mirror in a fun way to the work i do in the hospital. A thrill to get a call from a tv legend david e. Kelly. Boston legal, the Practice Chicago hope and tomorrow he rolls out a new one called monday mornings. Im excited now to give you a little preview. Coming through. Welcome to chelsea general. This is the emergency room and its a trauma center. Get out of my way. Clear. Multiple traumas at once. This is the sort of place where they all end up. Multiple trauma and lots of action in this area. But you remember this dr. Tyler wilson comes in with the team of doctors to make it all happen. Thats what this hospital is all about. Its a singlelevel set, as you might imagine. Ways we can make it multiple levels. For example elevator over here that goes straight through. You go through that elevator and youre suddenly on a different floor. Are these real . Anything could be real. Were going to go to my favorite place at chelsea general, the operating room. This is an operating room that youre going to see where we could actually perform surgery. We wanted the entire room to be real. So, nothing in here is out of place. Nothing doesnt belong. This is what a real operating room looks like. This is a microscope we use to perform surgery. Be able to move this microscope all around and focus in on different parts of the head. If i had to do surgery because someone needed it on the set, i could do it right here in this room. But chelsea general is like every other hospital. Sometimes complications occur. People are held accountable here in room 311. All right, lets get started, shall we . This is the room that very few people know about. Even fewer people get to see. Its room 311. Our characters often sit in the same seats, for example, and theyll have villanueva usually a big presence in the back of the room. This is the place, really, that you never want to be. If you can avoid it. Literally this walk where the doctors hear for the first time that theyre the ones in the hot seat when they come to this podium over here. You see its a glass podium. People can see their body language. The only person who sits in the same seat every time is dr. David hearting. He is the boss. He is the only person who can see, he can read everyones expressions and that was critically important. The other goal of 311 was to make sure we learn from mistakes. This is how medicine and science moves forward. The worst thing of all that a mistake occurs and no one learns from it. Room 311 makes sure that doesnt happen. Those meetings that we just saw, those are a real thing. Many of the story lines on monday mornings are from my own experiences not only as a doctor, but as a journalist. And action. This is our writers room, essentially. We brain storm a lot in here and just come up with ideas and i think we all sort of try ideas off each other and put them out there like trial balloons. Ill come up with a story and ill be like, is that possible . We can do that, right . And then youll talk me through a lot. Ill call, how do i do this . A story we did for cnn about this doctor, dr. Chung who is down in texas, military doctor and theyve been focusing on trying to create a presence in really, really tough spots. War zones, areas that are difficult to get to. Be here controlling a robot in the hospital or around the world, right . This news story inspired one of the episodes. Dont hit the robot. Had a 20yearold medic who has never done anything like this before who is basically going to be talked through a major brain operation. Youre going to need three packets of sutures, 10 blade and as many little clamps as you can find. Even though its scripted drama, you know, the auth authenticity and making sure the facts are right and really spending so much time on that stuff is that important. I joke with these guys a lot because i dont have any medical background, not a doctor but i research for ones on tv. And this Research Really matters. The cdc says about a third of tv viewers take action on Health Issues after hearing about them on primetime shows. Thats one reason the government makes their medical experts available to consult with hollywood studios, free of charge. We do that. We have actual medical technicians down on set. Several medical meetings and prep. We clear everything through you and you see everything. Was there anything else i could do . I think that we do the best we can to make sure its as close to the real deal as we can be. You have the other two steps in there, too, thats perfect. And next weekend right here, youll see my interview where doctors villanueva and huten as i know them. You will, too. Monday mornings premieres this monday night at 10 00 p. M. Eastern on tnt. A fun way, i think, to keep fresh food on the table. Im going to be with rapper t. I. Get this, were going to be planting a winter garden.

Tip it over but hold onto the little plant and pull it out. All three you guys did as a family there. Lets put arugula, the purple one down there. Arugula. Lets put that here. All right. Do you want to do some carrots . Yeah. Carrots and lettuce, when you plant them together, they help each other because they give off different nutrients in the soil that help each other, so thats called companion planting. How do you know when these things are ready to be picked. The lettuce, you can see, you can start picking it now. With the carrots, you want to wait a couple of months. Should we put something in the edible wall . Okay. Cool. Weve just demonstrated how easy it is to do this and how quick it is to do it. Thats pretty amazing. You guys have a problem now.
