Doctors dont know what causes them. There is no diagnosis, and there is no known cure. And limited funding to find one. Susan spencer on the case. Reporter her paintings are bright, often arresting. Wow. The colors are so brilliant. Thank you. Reporter but the source of those intense colors is intense pain. The first thing i feel is pressure in my temples. Almost like my head is getting squeezed in. Reporter priya has suffered chronic migraine attack most of her life. Five years ago, the cincinnati artist began trying to paint them. How do you paint a migraine . When i close my eyes, i feel this imagery kind of. It starts around the top, and it sort of floats down. And its a symphony of colors. Reporter but dont be fooled by that peaceful description. So are you painting in the middle of the migraine . It depends how functional i am and how painful it is. Reporter so sometimes you paint during the migraine . Yes. Reporter sometimes its overwhelming and you paint what you remember . Yes. I love all your work. Its beautiful. Thank you. Reporter and its most overwhelming priya has endured 25 attacks in a single month. The headache is the dominant symptom. It is so dominating that it crushes you. And youre unable to process or think or do anything at all. And it affects my vision. Sometimes it gets blurry, it affects your stomach. How does anybody live with this . What choice do you have . Here is my spray. Reporter she never leaves home without a purse full of medication. It doesnt stop the pain, but can reduce the severity and duration of the attack. So would you give yourself an injection . Yes. Reporter inside the Grocery Store . Ive done that. Ive gone to the rest room and given myself an injection. I think when people hear the word migraine, they think a really, really bad headache. How accurate is that . Its pretty inaccurate. Its a headache and its usually really bad, but it also has light sensitivity, nausea, sound sensitivity, smell sensitivity, brain fog, dizziness, and a host of other symptoms that are often attached to it. Reporter though the cause is unclear, migraine is a serious neurological disease that often runs in families, says dr. William young, a neurologist and headache specialist at Thomas JeffersonUniversity Hospital in philadelphia. And this can last for how long . Well, have i patients who never get rid of their migraine. Reporter come on. Every single day and every moment of every day. Reporter fortunately, thats rare. The disease, unfortunately, is not. About 40 million americans have migraine, a billion people in the world. A billion people in the world . A billion people in the world. Reporter thats about one in seven, living with whats ranked as the second most debilitating disease on the planet, right after back pain. Just how debilitating . Well, watch what happened to this tv reporter in 2011. Well, a very, very heavy we had a very everybody was sure that she had had a major stroke. It almost seems like she is speaking in tongues. Exactly, yes. Reporter and thats migraine . The most commonplace is in the vision part of the brain. But in her case, it was in the language part of the brain. The past couple of months it has gotten worse. Reporter a new class of drugs can reduce the number of attacks. And handheld electrical devices to block pain can help some patients. But there is no cure, and often no real diagnosis. Typically you cant see a migraine on a brain scan. Migraine is still a radically undertreated disorder. Reporter we met medical historian Katherine Foxhall in a new york city bookstore. Her recent book traces the history of the disease. So when is the first reported instance of someone having a migraine . Migraine is a disease that we can really trace back for thousands of years. Reporter over the centuries she says its been treated with everything from wrapping the patients head with ground up earth worms to bloodletting. As for why were not much better at treating it today one of the problems we have at the moment with migraine is really that its not taken that seriously. Reporter foxhall thinks thats largely because migraine affects three times as many women as men. Its often seen as an excuse. Its seen as a disorder of women, of, you know, women who cant really cope with modern life or who are too stressed. If this were men, we wouldnt be in the same situation . There is no way that the second most disabling disease in the world would get this little attention if it was happening to men principally. Reporter dr. Young heads up miles for migraine, which hosts running events. Dont let anybody ever say that its just a headache. Reporter aimed at raising awareness. If society tells you its not valid to have migraine headache, that you shouldnt be disabled, that its there because youre weak, you are not going to be a good advocate for yourself when it comes to getting treatment. Reporter even though its that common, people are uncomfortable admitting it . Right. So they hide it. They dont seek help. They dont talk about it because they know how little sympathy theyre going get if they say, you know, they need to miss work. Reporter that stigma, he says, has a dramatic effect on research. The National Institutes of Health Budget for arthritis, for example, is about ten times that for migraine, though the two have a comparable impact on society. If migraine was treated fairly by nih, it would get 240 million worth of research. It gets about 20. We obviously have limited funds. And so we have to be really careful how we spread them across the different diseases that were responsible for. Reporter linda porter is an nih director in the National Institute of Neurological Disorders and stroke. She says funding for Migraine Research is on the rise. Its a slow process. So weve gone in 2015 from about 22 million a year commitment, and now were getting up into the high 30s over a small number of years. Reporter is that satisfactory as far as youre concerned . You know, if, you know, the minimum wage goes from 6 to 6. 3 6 6. 50, no, its not satisfactory. Its shamefully poor. Reporter do you feel like this is getting enough attention . I feel like its getting enough attention. I think will the is a need for more funding in the area because there are some critical gaps. Reporter gaps she blames in part on a shortage of Migraine Researchers and the difficulty of treating people whose symptoms vary so widely. So headaches dont affect people all the same way. Reporter so this is hard . It is hard. Its not an easy equation of how i treat this patient to make them feel better. Because its not a one size fits all. Reporter small comfort to people like priya rama. She says the impact of migraine on her life is so great, shed even give up painting. If it also meant giving up pain. If i told you that tomorrow there is a cure, you know, you take this little pill once a month and youll never have another migraine. I would do it. Am i going to stop seeing these visions and not have anything to paint . Maybe. But if nascar hero ryan newman was released from a Florida Hospital two days after a frightening crash on the final lap of the daytona 500. Now newman was on his way to the checkered flag when a tap from behind sent his car spinning into the wall and then airborne. It took emergency teams 20 minutes to get him out of the wreck. It has some people asking how could anyone survive such a crash . Manuel bojorquez in daytona went looking for answers. There are so many areas on this car, not many you can look at that safety hasnt been thought of. Reporter andy petri has lived and breathed racing since 1981. Everywhere you can see where a car could possibly hit is protected. Reporter yesterday he showed us a series of features nascar has installed over several decades that he believes helped keep ryan newman alive at daytona, from padded doors this is a crush zone. It absorbs energy when something hits the side. Reporter to window nets. If anything happens in the crash, it keeps the arms and things from coming out. Reporter to stiffer carbon fiber seats. It can withstand a lot of impact. Crash into the wall, into the air goes newman. As spectacular as it was, we still expect our drivers to be able to get out and shake it off. Reporter petri was the crew chief for the late racing legend Dale Earnhardt sr. In the 90s. His death on the same daytona track sparked a safety revolution, requiring all drivers to use an upgraded seat belt and harness system. When you have an impact, it keeps your head from overtraveling and causing bigger injuries. Reporter drivers must also wear fire retardant racing suits, and new more crash absorbent walls have replaced concrete around the perimeter of nearly every track. If you think about it, race 200 miles an hour side by side, you can flip up in the air and 99 times out of 100, these guys are getting out of the car and walking away. This time it didnt happen. Reporter petris c helped build a generatio generaf sports car that will be used by every driver starting next february. But local sports columnist told me he believes speed restrictions on the race at daytona keep drivers clustered too close together and t t could re in a problem.
