This book highlights the key phases and central findings of Alzheimer’s Disease research since the introduction of the label ‘Alzheimer’s Disease’ in 1910. The author, Christian Behl, puts dementia research in the context of the respective zeitgeist and summarizes the paths that have led to the currently available Alzheimer’s drugs. As the reader is taken through the major developments in Alzheimer''s Disease research, particularly over the past thirty years, Behl poses critical questions: Why are the exact causes of Alzheimer''s Disease still in the dark, despite all the immense, worldwide research efforts in academia as well as in the pharmaceutical industry? Why has the majority of an entire research field kept focusing on a single hypothesis that establishes the deposition of the amyloid beta peptide in the brain as the key trigger of Alzheimer''s pathology, even though this concept has still not been convincingly proven in the clinics? Are there other hypotheses that might explainthe pathogenesis of this complex brain disease, and if so, why were these perspectives not adequately followed?

In this book, Behl tries to answer these questions. Starting with the historical background, the author illustrates the long and arduous research journey, its numerous setbacks, and the many alternative explanations for the disease, which have started gaining increasing attention and acceptance in the Alzheimer’s research community only more recently. 

With his deep dive into the history and progression of this research, including the most recent developments, Behl explains why he believes that it is high time to promote a paradigm shift in Alzheimer’s Disease research.

Aging represents a physiological and per se non-pathological and multifactorial process involving a set of key genes and mechanisms being triggered by different endogenous and exogenous factors. Since aging is a major risk factor in connection with a variety of human disorders, it is increasingly becoming a central topic in biochemical and medical research. The plethora of theories on aging – some of which have been discussed for decades – are neither isolated nor contradictory but instead can be connected in a network of pathways and processes at the cellular and molecular levels. This book summarizes the most prominent and important approaches, focusing on telomeres, DNA damage and oxidative stress as well as on the possible role of nutrition, the interplay between genes and environment (epigenetics) and intracellular protein homeostasis and introduces some genes that have actually extended life spans in animal models. Linking these different determinants of aging with disease, this volume aims to reveal their multiple interdependencies. We see that there is no single “perfect” theory of aging and that instead it is possible to define what the authors call the molecular aging matrix of the cell. A better knowledge of its key mechanisms and the mutual connections between its components will lead to a better understanding of age-associated disorders such as Alzheimer’s disease.

Dieses Buch führt in die wichtigsten Theorien des Alterns ein; es konzentriert sich auf Telomere, DNA-Schädigung, oxidativen Stress, die Rolle der Nährstoffversorgung bzw. -erkennung, das Zusammenspiel von Genen und Umwelt (Epigenetik) und die Proteinhomöostase und stellt einige Gene vor, die die Lebensdauer in Modellorganismen zu verändern in der Lage sind. Indem es die verschiedenen das Altern bestimmenden Faktoren mit Erkrankungen des Menschen verknüpft, sucht das Buch ihre vielfältigen Wechselbeziehungen und Abhängigkeiten aufzuzeigen und zu einer molekularen Matrix des Alterns zusammenzuführen.

Von diesem Buch werden alle profitieren, die sich einen profunden Überblick über die Mechanismen der Zellalterung und ihre Verknüpfung mit altersassoziierten Erkrankungen des Menschen verschaffen wollen.
