There are over 800 neuromuscular disorders and this can leave clinicians feeling lost as they try to diagnose and manage patients. On the basis of 66 adult and paediatric neuromuscular case vignettes, readers will be walked through using case histories and clinical manifestations as a starting point for diagnosis. For each case, diagnostic tools, disease pathogenesis, prognosis and treatment options are discussed. Symptoms, signs and syndromes are cross-linked to help the reader navigate the array of disorders. Accompanying tables explain differential diagnoses and 30 videos demonstrate clinical features. This second edition has been thoroughly updated as the neuromuscular subspecialty has developed from clinically and pathologically descriptive to making use of new diagnostic technologies and therapies. Neurologists at all levels, paediatricians, internists, geneticists, rehabilitation physicians, physiotherapists and researchers in the field will find this an invaluable guide, as they seek to familiarise themselves with this complex range of disorders.
