Scientists have speculated as to the nature of cerebrospinal fluid (CSF) - "the third circulation" or "vital spirit" for centuries. Just what is this mysterious bathing solution of the central nervous system? Is it a vehicle of transport for an "animal spirit" directing all our activities, as thought by Galen (Singer, 1956) or but a "modified tap water" (Halliburton, 1917)? With the advent of lumbar puncture, cerebrospinal fluid has become a readily available and important means of studying disease affecting the nervous system. In recent years, many sophisticated tools including com puter guided gas chromatography/mass spectrometry and high performance liquid chromatography have made it possible to identify and quantify many constituents of this fluid. The CSF has an enormous, though largely "untapped", potential in aiding diagnosis and evaluating treatment of many neurological, psychiatric and systemic disorders. As the ependyma is only a diffusional barrier between the CSF and extracellular fluid of the brain for many compounds, changes in the concentration of these compounds in the CSF may reflect disease processes in the brain.

Given the evolution of cerebrospinal testing (CSF) testing methods, the near future is certain to see an explosion of new CSF analysis methodologies. Broad-based and extensively illustrated, Cerebrospinal Fluid in Clinical Practice provides in-depth coverage of CSF examination and analysis, CSF physiology and pathophysiology, approach to diagnosis, and future directions in CSF analysis. It examines the alterations of the composition of CSF in relation to diseases and disorders of the nervous system, emphasizing the findings that are useful in clinical practice. This expansive reference is perfect regardless of your level of experience in central nervous system diseases. Provides in-depth coverage of CSF examination and analysis, CSF physiology and pathophysiology, approach to diagnosis, and future directions in CSF analysis. Explores the gamut of all CNS infections for a broad but detailed review of the scope of neurological disease. Contains detailed discussion on the proper use of specific diagnostic screens on CSF, so you may gain knowledge on how new diagnostic methods impact clinical medicine. Incorporates extensive illustrations and tables, with visual emphasis on diagnostic, laboratory, and anatomic data.

The cerebrospinal fluid (CSF) is an invaluable diagnostic tool in clinical neurology, not only in the evaluation of inflammatory, degenerative, and malignant diseases of the nervous system, but also in the diagnosis of all forms of cerebral and subarachnoidal bleedings. The CSF can be easily obtained by lumbar puncture and a set of basic analyses can be conducted using relatively simple laboratory methods. By combining different CSF parameters, a wide range of diagnostic entities can be identified. However, properly interpreting the test results requires a high level of expertise and cannot be achieved by just reporting on individual analytic values. This book covers essential aspects of cerebrospinal fluid analysis and its use in the diagnosis of common neurological diseases. The first part addresses preclinical aspects such as the history of CSF, as well as the anatomical, physiological, and biological background of this valuable fluid. In addition, CSF collection, its preanalytical and methodological implications, and the increasing number of disease-specific markers in CSF are discussed in detail. Lastly, CSF analyses are put into context with clinical syndromes, demonstrating their diagnostic value in neurological clinical practice. Cerebrospinal Fluid in Clinical Neurology helps readers understand the preanalytical and analytical aspects of CSF diagnostics and offers a valuable reference guide for interpreting CSF results during the clinical work-up for neurological patients.

cytochemical techniques (ICC) which provide a useful adjunct to investigations by immunoblotting. A particular advantage of a cytochemical approach to the investiga tion of mitochondrial disorders is that it allows the mosaic distribution of certain of these defects to be detected, whereas the tissue homogeniza tion involved in conventional enzyme assays or immunoblotting precludes this. A further advantage of MEA or ICC is that only small amounts of tissue are needed, which is important since many of the affected patients are infants or small children. The main aim of this communica tion is to outline ways in which these techniques can be used in the diagnosis and further investigation of mitochondrial disorders. Reference will be made not only to those situations in which MEA and ICC offer advantages over standard enzyme asays and immunoblotting but also to contexts in which the reverse applies. 4. 2 MATERIALS AND METHODS Muscle biopsies for cytochemical investigation were snap-frozen using isopentane cooled to - 150°C in liquid nitrogen. Samples were stored in heat-sealed polythene packets in the vapour phase of liquid nitrogen containers. 4. 2. 1 Microphotometric enzyme assays Frozen sections 8 Jlm thick were cut using a Reichert-J ung Frigocut cryostat microtome equipped with motor-driven cutting action to maintain maximal reproducibility of section thickness. Sections were picked up on microscope slides and air-dried for 15 min at room temperature.

This single-volume reference covers the natural course, treatment, and management of all neurological diseases affecting the brain, spinal cord nerves and muscles.

Diagnostic Reference Index of Clinical Neurology aims to give the busy clinician a fast, easy-to-use guide to the core neurological literature published from 1980 to 1986. This book is divided into two sections, key words and references. The keywords section consists of neuroscience terms and each main entry is followed by reference citation numbers and corresponding references. This index, unlike the usual computerized systems for literature retrieval, is structured around clinical problems and uses the approach and terminology of a practicing neurologist. The contents were sources from the full text of articles that were published in critical core of fourteen major international English-language journals in medicine and neurology. This book will be of interest to neurology students and to practicing clinical neurologists.

Physiologic compartmentalization effectively isolates the central nervous system from the rest of the body. This isolation not only provides protection of its delicate function from aberrant peripheral influences but also impedes its diagnostic evaluation. Cerebro spinal fluid (CSF) bathes the brain and spinal cord, is in dynamic equilibrium with its extracellular fluid, and tends to reflect the state of health and activity of the central nervous system. CSF examination is the most direct and popular method of assessing the central chemical and cellular environment in the living patient or mammal. The purpose of this multidisciplined reference text is to provide the sophisticated knowledge of CSF physiology and pathology necessary for the meaningful interpretation of data obtained by various types of CSF analysis. The methodology for reliable CSF collection, storage, preparation, and analysis is discussed with respect to individual, somatotropic, chronologic, endorcinologic, pharmacologic, and possible artifactual var iations in CSF composition. These essential aspects, which ensure the validity of CSF data, are presented to aid the investigator in clinical and experimental protocol formu lation and in elimination of possible sources of error.
