Few medical or scientific addresses have so unmistakeably made history as the presentation delivered by Alois Alzheimer on November 4, 1906 in Tübingen.


The celebratory event, "Alzheimer 100 Years and Beyond" organized on the initiation of the Alzheimer community in Germany and worldwide, in collaboration with the Fondation Ipsen, was the highlight of the Year of Alzheimer. However, beyond these few months of tributes, the centennial offers a unique opportunity to assess both the progress achieved and the uncertainties remaining. This volume, a collection comprised mainly of articles by the invited speakers and also of a few other prominent researchers, is meant to be a record of those events.
