Cerebral Energy Metabolism and Metabolic Encephalopathy

by D. W. McCandles

In recent years, there has been rapid growth in knowledge pertaining to the nervous system. This has, in some measure, been due to the development and application of a number of techniques such as the 2-deoxyglucose method and microchemical methods for measuring metabolites and regional cerebral blood flow. Data from the application of these techniques are just beginning to be collected, and the next few years promise to bring many new and exciting findings. The study of energy metabolism in brain is particularly interesting due to the fact that although the brain has scant energy reserves (as compared with the liver), it has one of the highest metabolic rates in the body. Recent studies from several laboratories have shown a surprising divergence of re­ sponses to metabolic insult in different areas of brain. In this regard, the cer­ ebellum, for example, may have metabolic features which are uniqve from those of any other region. The high-energy phosphate compounds ATP and phos­ phocreatine, supplied by the oxidative metabolism of glucose, are necessary for normal cerebral functions such as the maintenance of membrane potentials, transmission of impulses, and synthetic processes. Interruption of substrate or "poisoning" of the system by a variety of means lead to a rapid change in cellular energetics, and ultimately cell death. From the clinical standpoint, an interesting feature of metabolic encephalopathy is that in many cases, early diagnosis and treatment may result in a rapid reversal of symptoms.

Cerebral Hemorrhage (Acta Neurochirurgica Supplement #105)

by Liang-Fu Zhou Guohua Xi Xian-Cheng Chen Richard F. Keep Feng-Ping Huang Ya Hua Yi-Cheng Lu Karin Muraszko

Cerebral hemorrhage is a common and often fatal subtype of stroke. while in the past it has received relatively little attention compared to ischemic stroke, there have been major advances in our understanding of this devastating form of stroke. The papers by world experts cover the field from molecular biology to clinical trials.

Cerebral Ischemia

by Werner Hacke Michael Hennerici Herman J. Gelmers Günter Krämer

Despite a worldwide reduction in its incidence, stroke remains one of the most common diseases generally and the most important cause of premature and persistent disability in the industrialized countries. The most frequent cause of stroke is a localized disturbance of cerebral circulation, i.e., cerebral ischemia. Less common are spon­ taneous intracerebral and subarachnoid hemorrhages and sinus ve­ nous thromboses. The introduction of new diagnostic procedures such as cranial computed tomography, magnetic resonance imaging, digi­ tal subtraction radiologic techniques, and various ultrasound tech­ niques has led to impressive advances in the diagnosis of stroke. Through the planned application of these techniques, it is even possible to identify the pathogenetic mechanisms underlying focal cerebral ischemia in humans. However, these diagnostic advances have made the gap between diagnostic accuracy and therapeutic implications even greater than before. This fact can be easily explained. In the past, therapeutic studies had to be based on the symptoms and temporal aspects of stroke; it was impossible for early investigations to consider the various pathogeneses of cerebral ischemia. Inevitably, stroke patients were treated as suffering from a uniform disease.

Cerebral Ischemia: Molecular and Cellular Pathophysiology (Contemporary Neuroscience)

by Wolfgang Walz

The human brain represents about 2% of the body weight, yet it accounts for approximately 20% of aerobic metabolism. This high dependency on energy-consuming processes is mainly caused by the active transport of ions, which is necessary to compensate for the transmembrane ion currents that are part ofthe complex signaling processes in the brain. Ninety-five percent ofthe brain's ATP is derived from mitochondrial oxidative phosphorylation. Since that organ' s storage capacity for oxygen is minimal, any interruption of oxygen delivery to brain cells willlead to changes in membrane excitability and, there­ fore, to disruption of neuronal signaling within seconds. It seems that mamma­ lian brain is especially vulnerable to such an interruption, since oxygen deprivation leads to activation of ion channel mechanisms in neurons that impair their communications. Thus, the function of the brain as a coordinator of vital homeostatic reflexes, and complex body reactions to external challenges, depends critically on the rate of oxygen delivery and oxygen consumption. Oxygen delivery depends on two variables described in the Fick relation­ ship: volume flow rate ofblood and the arterial oxygen content. A reduction in either of these two variables will have serious effects on vital brain func­ tions. Reduction of arterial blood flow to the brain can be caused by cardiac arrest, shock, carotid occlusion, Of hypotension (global ischemia). Oxygen content is progressively decreased in asphyxia (including drowning).

Cerebral Ischemia and Basic Mechanisms

by Alexander Hartmann Frank Yatsu Wolfgang Kuschinsky

In this volume, one of a series of monographs devoted to the problems of cerebral ischemia and related topics, we present the proceedings of an international conference on Cerebral Ischemia and Basic Mechanisms held in Bad Schachen/Lake Constance, Germany in June 1992. The enormous progress in research recently on the basic mechanisms associated with cerebral ischemia has provided greater insight into the pathophysiological mechanisms of reduced brain perfusion and decreased cerebral metabolism. The high technology instrumentation used to unravel the intricacies of cerebral blood flow and metabolism includes positron emission tomography and magnetic resonance imaging. A description of sophisticated neurophysiological techniques will give the reader insight into new models of reversible and irreversible tissue damage and changes at the molecular level have been described. The therapeutic approaches which have developed from this re­ search have been or will be used in clinical trials and will open new avenues in the treatment of stroke. The organizers of the meeting would like to thank the advisory board for its helpful suggestions and the Deutsche Forschungsgemeinschaft and other sponsors for their important support.

Cerebral Ischemia and Calcium

by Alexander Hartmann Wolfgang Kuschinsky

Although many books deal with isolated problems of calcium disturbance in relation to cardiac and cerebral function, this is the first to focus specifically on calcium metabolism and cerebral ischemia. Internationally acknowledged experts present recent data and new concepts in an interdisciplinary approach to the subject. They examine basic information on the pathophysiology of cellular events, the damage caused by excitotoxic substances, and the effects of calcium antagonistic drugs as measured in experimental animals. These contributions may help lead to possible therapeutic interference for the prevention of calcium imbalance.

Cerebral Ischemia and Dementia

by Alexander Hartmann, Wolfgang Kuschinsky and Siegfried Hoyer

In contrast to dementia of the Alzheimer type, the subject of dementia subsequent to cerebral ischemia has been discussed rather rarely. Now this book provides a summary of the brain morphology, neurochemistry and clinical aspects of dementia subsequent to cerebral ischemia. The contributions discuss the similarities and differences between the two predominant dementia types. The broad range of aspects cover 1) the morphology and morphobiology of brain tissue during aging and under the two pathological condi- tions, 2) the neuropathochemistry of post mortem brain tissue of patients as well as brain tissue from experimental animals, 3) CSF changes during aging and in dementia states and 4) clinical research, mainly using brain imaging tech- niques to differentiate between dementia types and to find a basis for rational therapeutic approaches.

Cerebral Ischemia and Hemorheology


This book contains the scientific contributions presented during the inter­ national symposium "Cerebral Ischemia and Hemorheology", held in Germany in June 1987. The purpose of the symposium was to bring together experts in the fields of cerebral circulation and rheology, in order to increase the knowl­ edge and scope of both of these groups by making the members of each group more aware of work in the complementary field. The organizers hoped to stimulate the discussion between both groups and to reach adecision about whether the alteration of rheologie parameters might change the course and fate of cerebral ischemia. The contributions also report on clinical and basic studies pertinent to the topic of the symposium. The book is a comprehensive description of the state of the art wich may help to define what is known and to find new strategies to better und erstand metabolie, circulatory, and rheologie changes during cerebral ischemia. The selection of papers for publication was the task of the advisory board. The editors would like to thank the members for their critical analyses and suggestions; they are: Shu Chien, New York; F. Gotoh, Tokio; K.A. Hossmann, Cologne; G. Schmid-Schönbein, Aachen; L. Symon, London; and F. Yatsu, Houston.

Cerebral Localization: An Otfrid Foerster Symposium

by K. J. Zülch, O. Creutzfeldt and G. C. Galbraith

The demonstration of the basic brain mechanism through studying the partially commissure-sectioned case appears to be a most prom­ ising enterprise. The work with animals of HAMILTON and others in elucidating psychological brain process heretofore not imagined are mere indications of what the potential seems to be. Study of the partially disconnected patient seems equally revealing and productive in showing how many high level cognitive activities are managed in the cerebral flow of information. With respect to the issue of localization of function, it would seem clear that those cerebral areas clearly involved in the im­ mediate processing of raw sensory information can be selectively and specifically isolated and disconnected. In other words, the informational products of the long axonal type cells of Golgi, which MARCUS JACOBSON claims are the brain cells under strict genetic control, can be isolated, whereas the products of more complex and integrative mental activities which are managed by the more mutable Golgi type II cells do not seem to be so spec­ ifically disposed. Thus, these data suggest the lateralized spe­ cialities of the various left and right brain areas can make their contribution to the cerebral activities of the opposite hemisphere through almost any callosal area regardless of its size and loca­ tion. Indeed, this interpretation suggests to me that the long­ standing issue of the extent of localization could be better un­ derstood by considering the dichotomy in genetic specification as offered by HIRSCH and JACOBSON (1974).

The Cerebral Microvasculature: Investigation of the Blood-Brain Barrier (Advances in Experimental Medicine and Biology #131)

by Howard M. Eisenberg

As traced by Uichael Bradbury in his recently published monograph, The Concept of a BZood-Brain Barrier, the idea of a scientific challenge is just about as old as the twentieth century. Curiously, it remains undefined. Is it a structure or structures as some use the term, or is it a reciprocal per­ meability, a force-flow relationship, as do others, or is it a group of processes, some more specialized than others? Depend­ ing upon the observer, the method, and what is observed, it seems to be each of these or all. This Symposium takes as its focus of interest the micro­ vasculature of the brain and includes considerations of blood flow, the properties of vessel walls and the control of flow and permeability. In addition perturbations that change the characteristics of the flow of materials are given attention. By changing the usual focus of interest, the organizers, Drs. Suddith and Eisenberg, have given a fresh outlook to the subject and now, by publication of the Proceedings, have arranged for wide availability of these interesting papers. Keasley Welch v PREFACE A symposium on the cerebral microvasculature and its function in the blood-brain barrier was held at The University of Texas Medical Branch, Galveston, in the summer of 1979. Investigators from the United States and Europe met to discuss their recent work.

Cerebral Monitoring in the Operating Room and the Intensive Care Unit (Developments in Critical Care Medicine and Anaesthesiology #22)

by Enno Freye

In spite of today's increasing body of knowledge in regard to central nervous func­ tion and/or the mode of action of centrally active compounds, little is done to monitor those patients which are at risk of cerebral lesions either in the OR or in the ICU. Due to the inconsistency of reports regarding the application and the benefits computerized EEG and/or evoked potential monitoring will bring to the clinician, physicians still are reluctant to get involved with a technique, which they think, will have little or no effect on the outcome of a patients well being. However, due to the development in computer technology, data acquisition and comprehension, it now is possible to monitor such a viable organ as the Central Nervous System (CNS) on a routine base without being a specialist in neurology or electroencephalography. Thus, the book is intended to guide the clinician to use BEG and evoked potential monitoring in a day to day situation, without going too deep into technical details. As an improvement of cerebral care is needed, various representative cases underline the interpretation of EEG power spectra and evoked potential changes in regard to the underlying clinical situation. It is hoped that this book will serve as a guide to anyone who considers cerebral monitoring a necessity in today's patient care. This may be the anesthesiologist, the intensive care therapist, the nurse anesthetist as well as the medical personnel in the lCU setting.

Cerebral Monitoring in the OR and ICU

by Enno Freye

This comprehensive volume will serve as a complete guide to the clinical application of computer assisted systems in monitoring central nervous functions both in the OR and ICU. It presents practical guidelines and therapeutic indications for computerized EEG and Somatosensory Evoked Potential (SSEP) monitoring for the experienced user as well as the novice, leading the newcomer step-by-step to a level of advanced monitoring. Basic procedures and data handling are explained in a user-friendly and practical way. The book also describes what cerebral monitoring can do and what its limitations are. In addition, proper selection of the available monitoring devices, set-up procedures, the technique of electrode placement, trouble shooting and data interpretation are fully covered. Various typical cases underline how EEG power spectra and evoked potential changes are interpreted, how they are used in the light of other variables being measured how they can serve to get a deeper insight into the underlying clinical situation. In this respect representative and color illustrated examples further emphasize the link between this book and clinical practice.

Cerebral Palsy: Perspective and Clinical Relation to Perinatal Complications/Events in Japan

by Yoshio Matsuda

This edited book presents the latest information on epidemiology, pathophysiology, diagnosis, and some current topics covering all aspects of cerebral palsy. It offers a novel interpretation of a group of lifelong movement disorders, which now is an accepted notion that the causes of cerebral palsy are multifactorial rather than birth asphyxia. The book is organized into three parts, and it begins with illustrating the perspective of the disease. Then focuses on the relationship between clinical features of perinatal complications/events and cerebral palsy. The last part offers a hot topic of the prevention such as hypothermia, neuroprotection, and stem cell transfer. Since there is no cure for this congenital motor disability of cerebral origin, effective strategies for primary prevention are highly desirable. Effective strategies require an understanding of causal pathways and the Editor wishes to disseminate the experience and knowledge through this comprehensive volume to the readers.Cerebral Palsy - Perspective and Clinical Relation to Perinatal Complications/Events is a valuable source for clinicians, researchers, and medical staff who deal with the management of pregnancy and delivery. It also attracts clinicians worldwide who are interested in recent updates on this field.

This work was written by an international team of such specialists, providing a comprehensive mix of perspectives and expertise.

Cerebral Palsy in Infancy E-Book: targeted activity to optimize early growth and development

by Roberta B. Shepherd

Cerebral Palsy in Infancy is a thought-provoking book which introduces a new way of thinking on the development and use of interventions. Relevant to current practice, it advocates early, targeted activity that is focused on increasing muscle activation, training basic actions and minimizing (or preventing) mal-adaptive changes to muscle morphology and function. The authors present recent scientific findings in brain science, movement sciences (developmental biomechanics, motor control mechanisms, motor learning, exercise science) and muscle biology. This knowledge provides the rationale for active intervention, underpinning the need for an early referral to appropriate services. The book features methods for promoting relatively intensive physical activity in young infants without placing a burden on parents which include assistive technologies such as robotics, electronic bilateral limb trainers and baby treadmills. Cerebral Palsy in Infancy begins by specifying the guidelines for training and exercise, outlining the rationale for such intervention. It goes on to cover the fundamentals of neuromotor plasticity and the development and negative effects of limited motor activity on brain organization and corticospinal tract development. Neuromuscular adaptations to impairments and inactivity are discussed along with the General Movement assessment that can provide early diagnosis and prognosis, facilitating very early referral from paediatric specialists to training programs. The book ends with a section featuring various methods of training with the emphasis on preventing/minimizing muscle contracture, stimulating biomechanically critical muscle activity and joint movement. An ideal clinical reference for those working to improve the lives of infants suffering from cerebral palsy. CONTRIBUTORS: Adel Abdullah Alhusaini (Saudi Arabia); David I.
