dr. scott small whose's part of the research effort. >> alzheimer describes the disorder in 1906. but 's quite remarkable that for 40, 50,0 years after that there was no talk, no deception about alzheimer. mainly because it was thought to be part of normal aging. so in the 1980 there was a real serious attempt to try to understand this disorder. and the reason why one should be cautiously optimistic is because rational drug discovery, a basic principal of that is that the only way you will really cure a disease is if you understand its fundamental molecular mechanism. and we are only starting to shed light on that in the last 10, 20 years. >> we continue this evening talking to dr. henry kissinger about his recent conversation with vladimir putin in moskow. >> what putin has been trying to do is to conduct a very assertive foreign policy to put russia on the map again like his model peter the great who brought russia into europe. and so some of his apparent-- is his attempt to give russia an id

dr. scott small is a coauthor of the study and appeared february 3 to talk about the developments. >> early stage of alzheimers the patien patient dies and you find it in area a and you see alzheimers in two areas and then three areas and that's always been known for the last 20 years. and the question has always been does area a jump to b and c or are they just different areas that are vulnerable and pop in at different time points. that's a very difficult question to answer with human patients. what we did at columbia and brad hyman at harvard we used genetic engineering to introduce the pathology of alzheimers of area an in a mouse and that's the pathway. the pathway begins in the area called the interonal cortex and it's starts in the hypocampus and spread and that might account for why when we do follow patients with alzheimers it begins with mild forgetfulness but as it progresses you get language problems, etcetera. >> rose: how does it go from one cell and region to another. >> we don't
