Book Description
Alzheimer’s disease (AD) represents the most common form of dementia in the elderly population worldwide. AD is characterized by progressive neurodegeneration that leads to a gradual deterioration of memory and other cognitive functions. Given the global prevalence and impact of AD, there is a critical need to establish biomarkers that can be used to detect AD in individuals before the onset of clinical signs and provide mitigating therapeutics. The aim of this Special Issue is to discuss the current knowledge as well as future perspectives on the role of biomarkers in the screening, diagnosis, treatment and follow-up of AD.

Book Description
Alzheimer disease (AD) is a neurodegenerative disorder characterized by significant cognitive deficits, behavioral changes, sleep disorders and loss of functional autonomy. AD represents the main cause of dementia and has become a major public health issue. In addition, the number of patients suffering from AD is growing rapidly as the population ages worldwide. Memory impairment is usually the earliest clinical and core symptom of this disease. The diagnosis at a late clinical stage is relatively easy. However, a delay in the diagnosis is damageable for the handling of patients in terms of optimal medical and social care. The actual interest of the scientific head-ways is to optimize the diagnosis in prodromal stage of the disease and to propose personalized therapeutic solutions to individual patients. New revised AD diagnostic criteria include early alteration of cerebrospinal fluid (CSF) biomarkers: decrease of amyloïd peptides (Aβ42), and increase in tau and phosphorylated-tau (p-tau) protein concentration. This recognition of CSF biological biomarkers for the diagnosis of AD is a major step towards the “molecular” diagnosis and follow-up of the disease. Many issues are however still subject of debate. This e-book provides a comprehensive overview of the state of the art of fluid biomarkers for AD, e.g. which novel biomarkers should be implemented in clinical practice for diagnosis or for monitoring treatment or side effects, which ones are new for AD or related dementias or what is the potential of peripheral blood markers. Moreover, the e-Book provides practical guidelines how to optimally and efficiently develop and validate novel biomarker assays, and to document and control pre-analytical variation.

Book Description
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.

Book Description
Clinicopathological studies suggest that Alzheimer's disease (AD) pathology begins to appear ~10-20 years before the resulting cognitive impairment draws medical attention. Biomarkers that can detect AD pathology in its early stages and predict dementia onset and progression would, therefore, be invaluable for patient care and efficient clinical trial design. To discover such biomarkers, we measured AD-associated changes in the cerebrospinal fluid (CSF) using an unbiased proteomics approach (two-dimensional difference gel electrophoresis with liquid chromatography tandem mass spectrometry). From this, we identified 47 proteins that differed in abundance between cognitively normal (Clinical Dementia Rating [CDR] 0) and mildly demented (CDR 1) subjects. To validate these findings, we measured a subset of the identified candidate biomarkers by enzyme linked immunosorbent assay (ELISA); promising candidates in this discovery cohort (N=47) were further evaluated by ELISA in a larger validation CSF cohort (N=292) that contained an additional very mildly demented (CDR 0.5) group. Levels of four novel biomarkers were significantly altered in AD, and Receiver-operating characteristic (ROC) analyses using a stepwise logistic regression model identified optimal panels containing these markers that distinguished CDR 0 from CDR>0 (tau, YKL-40, NCAM) and CDR 1 from CDR1 (tau, chromogranin-A, carnosinase-I). Plasma levels of the most promising marker, YKL-40, were also found to be increased in CDR 0.5 and 1 groups and to correlate with CSF levels. Importantly, the CSF YKL-40/A[beta]42 ratio predicted risk of developing cognitive impairment (CDR 0 to CDR0 conversion) as well as the best CSF biomarkers identified to date, tau/A[beta]42 and p-tau181/A[beta]42. Additionally, YKL-40 immunoreactivity was observed within astrocytes near a subset of amyloid plaques, implicating YKL-40 in the neuroinflammatory response to A[beta] deposition. Utilizing an alternative, targeted proteomics approach to identify novel biomarkers, 333 CSF samples were evaluated for levels of 190 analytes using a multiplexed Luminex platform. The mean concentrations of 37 analytes were found to differ between CDR 0 and CDR>0 participants. ROC and statistical machine learning algorithms identified novel biomarker panels that improved upon the ability of the current best biomarkers to discriminate very mildly demented from cognitively normal participants, and identified a novel biomarker, Calbindin, with significant prognostic potential.

Book Description
The Neurobiology of Aging and Alzheimer Disease in Down Syndrome provides a multidisciplinary approach to the understanding of aging and Alzheimer disease in Down syndrome that is synergistic and focused on efforts to understand the neurobiology as it pertains to interventions that will slow or prevent disease. The book provides detailed knowledge of key molecular aspects of aging and neurodegeneration in Down Syndrome by bringing together different models of the diseases and highlighting multiple techniques. Additionally, it includes case studies and coverage of neuroimaging, neuropathological and biomarker changes associated with these cohorts. This is a must-have resource for researchers who work with or study aging and Alzheimer disease either in the general population or in people with Down syndrome, for academic and general physicians who interact with sporadic dementia patients and need more information about Down syndrome, and for new investigators to the aging and Alzheimer/Down syndrome arena.

Book Description
Almost four decades of innovative and intensive research on Alzheimer’s disease (AD) have brought major advances in our understanding of its pathogenesis, improved tools for diagnosis, and strategies for its treatment. This research has helped build a solid foundation of knowledge in the neurosciences and biological basis of AD and AD-related neurological disorders. Scientific background and insightful hypotheses are of major relevance in order to approach to an effective therapy for this devastating disease. Current Hypotheses and Research Milestones in Alzheimer's Disease contains 20 seminal chapters by authors with varying views on the neuroanatomical, neuropathological, neuropsychological, neurological, and molecular aspects of AD. These chapters grew out of “Current Hypothesis on Alzheimer’s Disease”, held in Viña del Mar, Chile, in November of 2007. Participants included the world’s leading Alzheimer’s researchers, whose work has illuminated AD investigations during the past few decades. Students, academics and medical professionals will find this text an invaluable addition to the study of this important subject.
