Few medical or scientific addresses have so unmistakeably made history as the presentation delivered by Alois Alzheimer on November 4,1906 in Tübingen. The one-hundred year anniversary of that event has been marked on several occasions in 2006, most notably at the very site of the original lecture, namely the Institute of Psychiatry of the University of Tübingen in Germany on November 2-5,2006.
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.
Over the last century of Alzheimer research (1906-2006), remarkable progress has been achieved in many areas:
- Progress towards understanding the pathogenesis: In this field progress has been very much dependent on developments in technology and other speciality areas. This was true from the very start: Alois Alzheimer's research would not have been possible without then-nascent microscopic staining techniques. It has proven true again over the last few decades, with molecular and cellular biology, genetics, and brain imaging all making contributions while benefiting from related fields. For instance, the discovery of the role of apolipoprotein E enabled Alzheimer scientists to apply research findings from the cardiovascular field. On the other hand, research into the pathogenesis of Alzheimer's disease revealed fundamental findings regarding protein aggregation, or regulated intramembrane proteolysis that has not only been applied to other neurodegenerative diseases but also paved the road to understanding completely unexpected signalling pathways.
- Recognition of the disease and clinical treatment. Although no cure has been found for Alzheimer's disease yet, the outlook is promising. Alzheimer's disease has ceased to be considered as an inescapable consequence of ageing.
- Economic and social considerations. With the aging of our society over the last 100 years, there has been a continuous increase in the number of Alzheimer patients and the burden for individual care-takers, as well as social and medical institutions. Demography has helped to make the public aware and prepared of the social and economic consequences of this devastating form of dementia.
Yet, none of the advances made have yet culminated in a fully satisfactory outcome. The pathogenic mechanisms of the disease remain inadequately understood and are at the centre of serious controversy, such as determining whether the observed lesions in post mortem brains of patients with Alzheimer's disease are the cause or a consequence of the disease; in no country have the public authorities provided fully for patients; and treatment options remain largely insufficient, despite hope from various symptomatic treatments and ongoing promising clinical studies targeting the pathological mechanisms.
Despite these shortcomings, the last one hundred years have been full and active ones. The aim of the meeting held in November 2006 in Tübingen, like that of this volume, is not to lay out the final legacy of a scientific corpus that is, to the contrary, constantly-developing, nor to crown the contributions of a specific researcher, at the expense of his colleagues or competitors. Instead, it is to honor the work accomplished and provide material for the history of science. We asked the invited authors to present their pioneering research explaining the conditions under which they were conducted from their viewpoint, and thus intentionally leaving room for a certain degree of subjectivity. Their testimonials contain unavoidably some contradictions, in particular regarding their part in certain essential discoveries. The editors of this book did not, at anytime, wish to take sides in the possible ownership squabbles, but only to provide readers with information from the very individuals who have made Alzheimer research what it is, over the past few decades. The only editing changes related to form alone - no article was changed in substance, none were censured and none were rejected. Some authors invited to present their research at the meeting in Tübingen were unable to hand in their contributions in time, however contributed significantly to the meeting, such as Monique Breteler, Nick Fox, Michael Hutton, Steven Paul, Gerard D. Schellenberg, Sangram S. Sisodia, Bengt Winblad, Bruce Yankner.
Lastly, several of the pioneers passed away too early to be able to attend the Tübingen meeting and contribute to this work: George Glenner, Henry Wisniewski, Tsunao Saitoh, Eva Braak, Jean-Louis Signoret, Yvon Lamour, Nelson Butler, Luigi Amaducci, and others. We dedicate this volume to them.
