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
Subjective cognitive decline (SCD) with self-reported concerns and mild cognitive impairment (MCI) are well-established to be at increased risk of developing Alzheimer’s disease (AD) dementia and a clinical continuum of dementia progression as a spectrum of AD. AD may develop from SCD to MCI (early MCI and late MCI) and eventually to AD. Nevertheless, until recently little was known about their pathophysiology associated with cognitive-behavioral syndrome. Although for researchers, scientists and clinicians, the pathophysiology of AD spectrum is an intriguing issue, delineating it in a clear way is far from easy. Taken together, in-depth understanding of neuroimaging-based pathology behind cognitive impairments across AD spectrum may help to develop new strategy for the early diagnosis and treatment of AD. Neuroimaging has been thought to potentially reveal the pathological mechanisms of AD progression. Individuals across AD spectrum are often associated with anatomical and functional brain alterations and cognitive impairment, most of the pathophysiology will focus primarily on the brain. To investigate brain structures and functions associated with cognition, neuroimaging will be the most appropriate tool.

Book Description
Interventions to delay or prevent the onset of Alzheimer’s disease (AD) would dramatically reduce the number of people living with dementia in the future. To reach this goal, it will be critical to identify individuals with preclinical AD, a clinically asymptomatic disease stage that is characterized by accumulation of beta-amyloid aggregates and neurofibrillary tangles in the brain, which are thought to contribute to neuronal injury and structural brain changes. The overarching goal of this dissertation was to better understand relationships between key pathological features of AD during this important preclinical timeframe and to assess the combined power of biomarkers to predict progression along the AD trajectory prior to the onset of clinical impairment. These experiments addressed two major questions: 1) are early indicators of preclinical AD better associated with biomarkers that capture multiple pathologies simultaneously than with a biomarker for a single pathology measured in isolation?; and 2) do longitudinal analyses of pathology and cognitive decline within individuals provide better indications of movement along the AD trajectory compared to cross-sectional models? To address these questions, three Specific Aims assessed relationships between multiple biomarkers and both their cross-sectional and longitudinal associations with brain change. Specifically, analyses were performed to investigate whether biomarkers for amyloid and neural injury predict longitudinal brain amyloid accumulation (Specific Aim 1), white matter microstructural changes (Specific Aim 2), and cognitive decline (Specific Aim 3) in late-middle-aged adults with elevated risk of AD due to parental family history and genetic factors. As hypothesized, measures of co-occurring amyloidosis and neural injury were more commonly associated with disease outcomes than markers of a single pathology, and longitudinal models enabled detection of early pathological and cognitive decline often not possible with cross-sectional approaches. This dissertation provides important contributions to the field by assessing the preclinical phase of AD using a unique cohort of individuals who were middle-aged and cognitively healthy at study entry and who are enriched with risk factors for AD; by investigating an extensive panel of multimodal biomarkers; and by examining longitudinally measured change within individuals in terms of both biomarker levels and cognitive performance.

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
This up-to-date, superbly illustrated book is a practical guide to the effective use of neuroimaging in the patient with cognitive decline. It sets out the key clinical and imaging features of the various causes of dementia and directs the reader from clinical presentation to neuroimaging and on to an accurate diagnosis whenever possible. After an introductory chapter on the clinical background, the available "toolbox" of structural and functional neuroimaging techniques is reviewed in detail, including CT, MRI and advanced MR techniques, SPECT and PET, and image analysis methods. The imaging findings in normal ageing are then discussed, followed by a series of chapters that carefully present and analyze the key findings in patients with dementias. Throughout, a practical approach is adopted, geared specifically to the needs of clinicians (neurologists, radiologists, psychiatrists, geriatricians) working in the field of dementia, for whom this book will prove an invaluable resource.

Book Description
As indicated by its title, this monograph deals chiefly with morphologically recognizable deviations from the normal anatomical condition of the human CNS. The AD-associated pathology is illustrated from its beginnings (sometimes even in childhood) to its final form, which is reached late in life. The AD process commences much earlier than the clinically recognizable phase of the disorder, and its timeline includes an extended preclinical phase. The further the pendulum swings away from the symptomatic final stages towards the early pathology, the more obvious the lesions become, although from a standpoint of severity they are more unremarkable and thus frequently overlooked during routine neuropathological assessment. For this reason, the authors deal with the hallmark lesions in the early phases of the AD process in considerable detail
