Book Description :

A lot of research on biomarkers for Alzheimer is being done in the last few decades. The aim of these studies is to find some method to ease the diagnosis of Alzheimers as early as possible. Such methods are a range of blood or CSF tests on one hand and several types of neuroimaging scans on the other. Many of the images coming both from laboratory and neuroimaging are very visual and illustrative. These images, accompanied by a short description, can perfectly explain the main results and usefulness of every biomarker. The objective of this book would be to summarize the most important studies made in this field. Few publications have systematically compiled results on this topic and only one as an atlas. Readers would be interested in this publication because it allows reviewing the current status of research by handily visualizing the results.

Book Description :

In view of the growing prevalence of AD worldwide, there is an urgent need for the development of better diagnostic tools and more effective therapeutic interventions. Indeed, much work in this field has been done during last decades. As such, a major goal of current clinical research in AD is to improve early detection of disease and presymptomatic detection of neuronal dysfunction, concurrently with the development of better tools to assess disease progression in this group of disorders. All these putative correlates are commonly referred to as AD-related biomarkers. The ideal biomarker should be easy to quantify and measure, reproducible, not subject to wide variation in the general population and unaffected by co- morbid factors. For evaluation of therapies, a biomarker needs to change linearly with disease progression and closely correlate with established clinico-pathological parameters of the disease. There is growing evidence that the use of biomarkers will increase our ability to better indentify the underlying biology of AD, especially in its early stages. These biomarkers will improve the detection of the patients suitable for research studies and drug trials, and they will contribute to a better management of the disease in the clinical practice. Indeed, much work in this field has been done during last decades. The vast number of important applications, combined with the untamed diversity of already identified biomarkers, show that there is a pressing need to structure the research made on AD biomarkers into a solid, comprehensive and easy to use tool to de deployed in clinical settings. To date there are few publications compiling results on this topic. That is why when I was asked to address this task I accepted inmediately. I am happy to present you a bundle of the best articles published about biomarkers for Alzheimer’s disease in recent times.

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 prevalence of neurodegenerative disorders is increasing dramatically and one of the major challenges today is the need of early and accurate diagnosis, the other is the need of more effective therapies -in turn the development of such therapies also requires early and accurate diagnosis-. The main hope for an earlier and more accurate diagnosis comes from the use of biomarkers. Much research is being done trying to solve the many interrogates related to the role of biomarkers in clinical practice, including the early diagnosis, differential diagnosis and follow-up of neurodegenerative disorders. This is a field where translational research is intense enough to make this topic interesting for basic researchers and clinicians. Indeed, the amount and quality of articles received in response to the call for contributions was very good. This eBook contains a good amount of high quality articles devoted to diverse techniques across several neurodegenerative disorders from different perspectives, including original reports, reviews, methods reports and opinion letters on biochemical biomarkers in biological fluids, neuroimaging techniques and multidimensional approaches linking clinical findings with biomarkers. The disorders covered are also diverse: Alzheimer’s disease, Frontotemporal Dementia, Dementia with Lewy Bodies, Huntington’s disease, Parkinson’s disease among others. As we can learn from articles in this Research Topic, biomarkers are allowing us to expand the knowledge on the biological and anatomical basis of neurodegenerative diseases and to implement diagnostic techniques in clinical practice and clinical trials.

Book Description :

This volume presents the proceedings of the symposium held in Toulouse on April 24, 1989, on the topic "Biological Markers of Alzheimer's Disease. " This sym posium was the fourth of a continuing and successful series of Colloques Medecine et Recherche organized by the Fondation IPSEN pour la Recherche Therapeutique, addressing various aspects of contemporary research in the field of Alzheimer's disease (AD). The series started in September 1987 with "Im munology and Alzheimer's Disease," followed 6 months later in Paris by "Gene tics and Alzheimer's Disease" and in September 1988 in Montpellier by "Neuronal Grafting and Alzheimer's Disease. " The present symposium was organized for the purpose of gathering the most current ideas concerning biological markers of AD. The papers presented at this symposium may be roughly subdivided into three groups. The first deals with the markers of AD at the level of the brain itself. These markers are studied either through the cerebrospinal fluid or through techniques such as nuclear magnetic resonance (NMR) - approaches which respectively aim at demonstrating the cerebral changes indicated by the debris resulting from the disease, or studying the possible neurochemical abnormalities that occur in the earlier stages of AD.

Book Description :

Alzheimer's disease (AD) is characterized by the deposition into the brain of amyloid peptide, which originates a cascade of inflammatory events leading eventually to neuronal death. These pathological events likely occur several years before the clinical manifestation of the disease, implying that potential therapeutical interventions are currently started too late to give beneficial results. Recently, growing attention has been paid to the Mild Cognitive Impairment (MCI), considered the prodromal phase of AD, as 80% of subjects with MCI have been shown to develop AD within 5 years. Several studies aimed to identify biological markers to differentiate between normal aging and incipient AD have been carried out, including cerebrospinal fluid (CSF) analysis and neuroimaging. In particular, the evaluation of CSF Amyloid beta (1-42) levels, together with tau and phospotau, are of help for recognizing early AD. Besides, a number of additional molecules are altered in CSF. Other early modifications have been observed in peripheral cells, such as fibroblasts and leukocytes, as well as in serum from patients. Biomarkers for AD represent important tools supporting the clinical diagnosis and the choice of potential therapeutic options. Moreover, they would be of great help for the selection of cohorts of homogeneous patients for clinical trials with new disease-modifying compounds. This book is aimed to give an update about MCI as prodromal Alzheimer's disease (AD), to discuss the main known pathological mechanisms at the basis of AD and to describe the possible biomarkers to be used for an early diagnosis of the disease.

Book Description :

Alzheimer's disease (AD) is a devastating neurodegenerative disease that slowly claims the memories and experiences that comprise the life experiences of individuals that suffer from the disease. Despite a continually accelerating pace of research and discovery, a viable therapeutic intervention for AD has yet to be realized. There are a multitude of factors that may contribute to this difficulty including the challenge of separating the overall disease of Alzheimer's from the clinically recognizable memory loss that occurs in what is now known to be the end-stage of the disease. Efforts to treat AD have increasingly turned toward very early disease states, before clinical signs and symptoms become apparent, as a number of clinical trials have failed to meet cognitive endpoints over the last 5-10 years -- potentially due to the sole recruitment of individuals already experiencing significant cognitive decline.One important aspect of AD treatment is identification. It is now recognized that the disease begins more than a decade before the signature symptoms of cognitive impairment become apparent. Identifying individuals in this "preclinical" disease state has become a primary focus of many investigators who believe that AD must be targeted and fought well before the clinical manifestations of memory impairment appear.Biomarkers, indicators of normal biological or pathological processes that may be studied as a means to give individuals a disease diagnosis, prognosis, or theragnosis -- provided a treatment is available for the disease in question -- are of paramount importance in many diseases. AD has proved a difficult target to nail down reliable, sensitive, and specific biomarkers. This is in part due to analytical difficulties in major, core biomarkers of disease and in part due to setbacks in clinical trials of promising therapeutic candidates.The current work begins with an overview of biomarker modalities used in AD; however, the primary focus is on protein biomarkers in cerebrospinal fluid (CSF). CSF provides an intimate window to the central nervous system that, in the case of AD, has shown the ability to identify and monitor disease progress over time in cohorts of cognitively normal and demented individuals. In an effort to pinpoint AD before clinical signs and symptoms manifest, biomarker research in preclinical AD has become a robust area of investigation. CSF biomarkers of amyloid pathology, neuronal damage, and neuroinflammation are discussed in two independent cohorts: the Adult Children Study (ACS) from Washington University in St. Louis and the Alzheimer's Disease Neuroimaging Initiative.The ACS cohort is comprised of middle-aged, cognitively normal individuals recruited on a volunteer basis from community dwelling participants with and without a family history of AD. The ADNI cohort is comprised of older individuals also recruited on a volunteer basis from community dwelling participants, though participants are recruited with respect to clinical status and include cognitively normal individuals, individuals with mild cognitive impairment, and individuals with AD, in addition to being older than the ACS cohort.In both cohorts, it was found that CSF markers of amyloid plaques -- one of two required pathological hallmarks that indicate AD -- changed earlier than those of tau tangles, the second required pathological hallmark.Currently, examining biomarkers on a group-wide basis is the best way to get an accurate picture of biomarkers at baseline and followup lumbar punctures (LPs). As the goal is to be able to give individual people a diagnosis and prognosis of their disease, the behavior of biomarkers is particularly interesting because studies have found that CSF A[beta]42 changes up to 15 or more years before cognitive signs and symptoms become apparent and, hopefully, beginning treatment in this period will be helpful not only for diagnosing for individuals with AD dementia, but also for individuals with very early disease.

Book Description :

Alzheimer s disease (AD) is the major form of dementia in the elderly, characterised by progressive decline in cognitive function and the gradual build-up of A amyloid deposits and neurofibrillary tangles in the brain. Due to our aging population, and increasing lifespans, this disease is reaching epidemic proportions: currently 35 million people are estimated to have AD worldwide and within a generation this figure is predicted to increase to 115 million. Although considerable progress has been made into our understanding of AD there is still no effective treatment and no definitive diagnostic test during life. It is now generally recognized that for any drug treatment to be effective, an early diagnostic test for AD is essential. This study investigated the effects of low testosterone and high levels of dietary fats that have been associated with the pathogenesis of AD, and determined whether their effects were more pronounced in APOE e4 carriers, using an animal model of AD. Cholesterol and certain cholesterol metabolite levels were altered by these factors and with age. The findings help demonstrate the inter-relationships between lifestyle factors, age-associated hormone changes in men and APOE genotype on the development of AD and indicate they exert their effects via modulation of brain lipid metabolism. Changes in levels of selected human plasma protein biomarkers were measured in the hope of finding protein changes that indicate AD pathogenesis or pathology. Similarly, a comprehensive screen of plasma lipid levels in AD and control subjects identified several potential novel lipid biomarkers, which together with apoE genotype and protein biomarkers such as the 430kDa reelin protein were analysed to determine their diagnostic significance. The work presented in this thesis supports the theory of a concurrence of changes in multiple factors in the pathogenesis of late onset AD and has identified a selection of candidate biomarkers, which potentially could produce a preliminary biomarker panel for the detection of AD.
