As human longevity continues to be extended, so will the impact of age-associated dementia on individual lives and society. Alzheimer’s disease as the most common cause of dementia in the elderly remains a sentinal problem and its underlying pathology is still poorly understood. Available therapeutic strategies require considerable refinement and the development of new therapeutic strategies need input from basic research. Thus continued efforts are necessary both to understand basic mechanisms of the condition and to achieve more powerfull therapies.This volume brings together the reports of basic scientists and clinical investigators. The chapters provide a spectrum of information valuable for clinicians and scientists. This issue bridges the gap between laboratory work in basic science and the development of urgently needed therapeutic strategies. Areas presented are the molecular and cellular biology of the disease, pathogenetic mechanisms and potential therapeutic targets, genetics, risk factors, strategies of prevention and treatment as well as practical aspects of medical and social care for patients with Alzheimer’s disease.
