Disorders of the Nervous System

The hippocampus is one of the most studied structures in the human brain and plays a pivotal role in human memory function. It's recognized function is reflected by the presence of an extensive body of neurophysiological, neuropsychological, anatomical, and neurocomputational literature that presents basic mechanisms, theoretical models, and psychological concepts. However, in the rapidly growing field of hippocampal research, the clinical aspects of diseases that affect the hippocampus are greatly under-represented, and clinical approaches and concepts are scattered throughout various clinical and basic scientific disciplines. This book explores clinical approaches to the range of diseases that affect the hippocampus. It brings together and reviews the common methods, clinical findings, concepts, mechanisms and, where applicable, therapeutic strategies for these clinical approaches. The clinical spectrum of hippocampal dysfunction encompasses a wide range of neurological, behavioural, and psychiatric symptoms and surpasses the ability to encode, store, and retrieve information. The relevance of hippocampal involvement in clinical diseases goes beyond mere neuropsychological deficits and includes psychopathological states in various conditions, such as acute amnesic syndromes, Alzheimer's disease, temporal lobe epilepsy (TLE), sleep, stroke medicine, limbic encephalitis, neurodevelopmental disorders, stress- and trauma-related disorders, depression, and schizophrenia.

During the First World War many soldiers suffered brain injuries, mostly from gunshot wounds. The localized nature of these injuries made them of special significance for neuropsychological studies and they were the subject of research by British and German psychologists and neurologists working in military hospitals. The work carried out by Walther Poppelreuter in Germany is of particular interest. He was one of the first to design and use precise experimental methods for neuropsychological assessment and analysis. Poppelreuter was also one of the first to suggest a relatively specific processing of visual submodalities such as movement, depth, form, and colour in the prestriate areas. Much of his practical advice on the management of patients is still of value. Anyone concerned with brain injuries, especially of the occipital lobe, can still benefit from his contribution. This translation makes this classic now available to a wider audience.

Epilepsy is one of the most common disorders of the brain, and these patients often suffer from memory problems. There are a number of reasons for this: seizures can directly affect the brain in ways that disturb memory; epilepsy often results from trouble in brain regions closely linked to memory; the treatment of epilepsy can affect memory; epilepsy can cause psychological problems, like depression, which interfere with memory. This book reviews all aspects of the relationship between this common and potentially serious neurological disorder and memory, one of the core functions of the human mind. The chapters review the history of the subject; the clinical features of memory disorder in epilepsy; neuropsychological, neuroradiological, neuropathological, and electrophysiological findings; the roles of anticonvulsant side effects and psychiatric disorder; and the scope for memory support and rehabilitation. The study of patients with epilepsy has revealed much about the workings of memory, yet there has been no recent review of this field of research. This book aims to this gap.

This book studies the organization of the white matter pathways of the brain. The book analyzes and synthesizes the corticocortical and corticosubcortical connections of the major areas of the cerebral cortex in the rhesus monkey. The result is a detailed understanding of the constituents of the cerebral white matter and the organization of the fiber tracts. The findings from the thirty-six cases studied are presented on a single template brain, facilitating comparison of the locations of the different fiber pathways. The summary diagrams provide a comprehensive atlas of the cerebral white matter. The text is enriched by close attention to functional aspects of anatomical observations. The clinical relevance of the pathways is addressed throughout the text and a chapter is devoted to human white matter diseases. The introductory account gives a detailed historical background. Translations of seminal original observations by early investigators are presented, and when these are considered in the light of the authors' new observations, many longstanding conflicts and debates are resolved.

This book provides an atlas of the normal human brain based on three dimensional reconstructions of magnetic resonance scans obtained in normal living adults as well as neurological patients with focal brain lesions. It provides detailed descriptions of sulci and gyri and illustrates how they appear in different brains. The book shows how different slice orientations obtained in the same brain produce different images that can be anatomically misinterpreted, in normal brains as well as brains with lesions. The book also addresses quantitative differences between the human brain and the brains of apes; gray and white matter differences between the hemispheres; and differences related to gender, age, and congenital deafness.

This volume provides up-to-date information concerning new applications of brain imaging to the study of Parkinson’s disease (PD). The chapters, written by experts in this field, focus on the various imaging methodologies that have recently been used to study the natural history of the disease with emphasis on each of the distinctive clinical features that characterize the disorder (e.g., bradykinesia, rigidity, tremor and gait disturbance). Individual chapters also address the role of imaging in differential diagnosis, and in the evaluation of cognitive dysfunction/dementia in parkinsonian patients. Considerable emphasis is placed on potential applications of neuroimaging in clinical trials to assess new pharmacologic and surgical treatment strategies for PD, including deep brain stimulation (DBS), cell transplantation, and gene therapy. In-depth discussion is provided on advanced imaging applications, including rest-state and activation fMRI, volumetric MR, PET assessment of dopaminergic and cholinergic neurotransmission, and echosonography. Additional topics cover recent developments in the use of brain imaging to assess disease mechanisms including neuroinflammation, protein aggregation, and disordered brain network organization in PD.

This new edition covers advances in understanding immunological and inflammatory responses in the nervous system, research driven by the potential to use knowledge of the molecules and mechanisms involved to intervene in, and arrest, neurodegenerative disease processes. This book covers developmental aspects of immune/inflammatory responses in the central nervous system (CNS), basic aspects of glial function, as well as inflammatory mediators, their mechanisms of action, clinical importance, and sites of infection. There is also coverage of the major diseases of the CNS, including stroke, brain injury, multiple sclerosis, and Alzheimer's disease. Throughout, the focus is on the underlying basic neuroscience, clinical relevance, and the potential for therapeutic interventions. The book will be useful for improving the diagnosis of neuroimmune diseases and determining therapeutic measures.

Key thoughts leaders and practitioners in personalized medicine distil its current status, future directions, and recommendation for successful implementation of for brain disorders. This text is a summary of the “science to patient” continuum in and integrative neuroscience. Included are measures of genes using whole genome approaches and SNIPS, as well as BRAINmarkers of direct brain function such as brain imaging, biophysical changes and objective cognitive and behavioral measurements. The chapters provide a review of relevant literature; show the personalized diagnostic and treatment prediction solutions for patient care achieved through integrative neuroscience, providing a practical guide. This book provides a summary of the key translations from laboratory discoveries to patient and reimbursement issues, in personalized medicine.
