This is a book for practicing clinicians, particularly neurologists and clinical geneticists, about the commonest muscular dystrophy of adult life world wide, mytonic dystrophy. Chapters on the different aspects of management and therapy are written by world authorities on the topics: together, they represent the only comprehensive account for a condition which is currently very poorly managed because of its great variability. It should form part of any book list in neurology, muscle disease or genetics.
