parkinson's with his own adult stem cells. heart damage, a number of papers out. spinal cord injury. in fact, embryonic.... >> woodruff: all with adult. >> with adult stem cell. >> woodruff: that don't involve the destruction of embryos. >> that's right. 50,000 or more patients a year treated with adult stem cells. it's true most of these have been for mayor owe diseases, anemia, cancers. now we're seeing adult stem cells actually help patients-- published evidence-- for things like parkinson's spinal cord, m.s., juvenile diabetes and the list goes on. >> woodruff: if that's the case, dr. snyder, why are the embryonic stem cells so important? >> first, i would like to respond to dr. prentice's comment that there's been demonstrated efficacy. i can tell you that i've reviewed many of those studies. i myself in our lab do research comparing various kinds of stem cells head to head. and the evidence that blood stem cells or that bone marrow- derived stem cells are useful for diabetes or for stroke or for many of the diseases that

most diseases-- parkinson's-- they have multiple causes. so one doesn't think of simply a single factor like genes. that's one way of producing the disease but there are other ways of producing it also. >> yeah. that's exactly right. so one of the ways that scholars over the last several years have tried to understand this is to look at that 10% of cases where we know a miscreant gene and a sick protein have caused the disease. and so basically one can take, for example, a family. and here we have a pedigree with individuals in light and dark coloring, those who the light color having the disease, those with dark don't. and one can essentially profile d.n.a. and use profiles of d.n.a. to screen the families and essentially in that manner find the disease-causing genes. and i'll just tell you that it's... >> rose: and once you do that? >> well, the question is once one has a disease-causing gene, can one use that both to understand the disease and ultimately, of course, to find therapy. and the answer is that thus far there have been huge in

i see the neurologist, he tells me that the good news is that you don't multiple sclerosis or parkinson's but you may have a.l.s. so i had to go home and look it up. i knew about lou gehrig but very little else. it turns out that a.l.s. is a disease about which almost nothing is known. it was identified by a french neurologist about 75 years ago. since then, we've learned more about how it works but very little about what to do about it. (inaudible) the painter, the plumber, the bus driver, there's nothing you can do to (inaudible) do nothing. because i'm a teacher, i was able to continue for two years after the initial diagnosis. that's actually what kept me going, the fact that i could continue, i could dictate, i could think, i could, so to speak, write. therefore that's what kept me going. >> rose: help us understand how you think about dying and help us understand how you think about what insights you have about living. >> well, i'm better on living than i am on dying because by the time you think about it, it's too late. but i can tell you a little bit about the peculiarity of knowi

for instance, there are now over 75,000 parkinson patients worldwide who've had tiny electrodes implantedin their brains. doctors say the operation significantly reduces tremors and allows patients to rely less on medications. >> by the way, nobody is picketing, protesting, oh, people putting computers in their brains -- that is somehow unnatural or defies the way things should be. >> reporter: bioethicist brugger worries that science will soon cross thline to where brain implants will not simply heal patients, but enhance their ability to think and compete. >> if we move in this direction of radical human enhancement, are we going to develop those who are and those who aren't? the enhanced and the unenhanced? i mean, lord, we can't even find the money to get everyone braces who needs braces. >> when the technologies are only affordable by the rich they actually don't work very well. consider mobile phones. 15 years ago somebody took out a mobile phone in the movie. that was a signal this person is very powerful and wealthy, and they didn't work very well. now 5 billion people out of 6 bi

you can't cure parkinson, you can't cure multiple scpler row sister louehrig disease, it is hard to figureout where to go with this and it is only very recently that they discovered some real clues that can help this renaissance in drug development where people think they know what to do, what kind of drugs to develop that might actually make a difference. it remains to be seen, but for the first time people are really optimistic, they say we know now what to do to try to fight it early, we can find signs of this disease ten or 20 careers before they ever get it. >> rose: is genetics playing a role in this? >> to a certain extent. if your family members have it, you have a higher risk, but most -- they don't have many, they have a few genes that are absolute predictors you are going to get alzheimer's but it is so rare only a few families have them, for most people, it is kind of like a bolt out of the blue, it is probably genetics but they don't know what the genes are, here is a field that is just sort of moribund and all of a sudden there is this explosion of knowledge and information a
