Inherited Ataxias

Download or read book Inherited Ataxias written by A. E. Harding and published by Lippincott Williams & Wilkins. This book was released on 1993 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this volume, more than 50 leading international experts review the latest scientific and clinical observations on inherited ataxias. The book demonstrates how molecular genetic studies, as well as recent physiological, neurochemical, and clinical data, have generated new concepts on the nosology of these disorders. Close attention is given to the important practical applications of these new findings - in diagnosis, prognosis, and genetic counseling, in development of tests for prenatal diagnosis and carrier detection, and in the search for more effective therapies. The opening chapter identifies the clinical features that distinguish the various inherited ataxic syndromes and presents a classification based on etiology, mode of inheritance, age of onset, and associated clinical features. A major portion of the book focuses on current clinical and molecular genetic studies of different forms of inherited ataxia. Coverage includes a molecular analysis of the Friedreich's ataxia locus and extensive studies on autosomal recessive spastic ataxia of Charlevoix-Saguenay, ataxia telangiectasia, dominantly inherited spinocerebellar ataxias, Machado-Joseph disease, and inherited prion diseases. The contributors provide detailed information on the various clinical phenotypes of each form of inherited ataxia and thoroughly explain the use of linkage analysis and other molecular genetic techniques to localize and isolate the genes responsible for these diseases. The book also reviews the most significant research findings on neurotransmitters in the cerebellum, on the phosphoinositide second messenger system in cerebellar degenerative disorders, and on oligodendrocyte-associated andmyelin-associated inhibitors of neurite growth in the adult nervous system. The contributors assess recent progress in developing drugs for treatment of ataxias and other cerebellar movement disorders and identify new targets for pharmacological intervention. Experimental therapeutic observations on cerebellar grafting in heredodegenerative ataxia are also presented. This volume is an invaluable reference for clinicians treating patients with ataxias or counseling families at risk for inherited neurological diseases. It is also a rich source of ideas for molecular geneticists and for neuroscientists investigating disorders of the cerebellum.
