The neurochemical indicators which help in the assessment of risk or the presence of Alzheimer's disease are known as Alzheimer's disease biomarkers. They help in an early diagnosis as well as tracking the progress of the disease in a reliable manner. The analysis of biomarkers becomes vital to the management of this disease since the neuropathologic changes occur years before the symptoms are seen. The most important biomarker used for the detection of Alzheimer's disease is amyloid beta. One of the novel approaches towards research on Alzheimer's disease is the usage of autoantibody. These can be used as both biomarkers and for future treatment. This book elucidates the concepts and innovative models around prospective developments with respect to novel biomarkers in Alzheimer's disease. It will also provide interesting topics for research which interested readers can take up. Researchers and students in this field will be assisted by this book.
