Movement Disorders and Inherited Metabolic Disorders: Recognition, Understanding, Improving Outcomes

Inherited metabolic movement disorders are a significant and rapidly evolving field of study, linking two subspecialty areas of childhood-onset movement disorders and inborn errors of metabolism. Increasing the chance of early recognition of inherited metabolic movement disorders can have significant therapeutic implications for patients. Containing information on new disorders of post-translational modification and autophagy and their identification and treatment, there is thorough coverage of disorders of amino acids, energy metabolism, and lysosomal storage, amongst others. This key resource explores future directions in the field including next-generation genetic sequencing and novel therapeutic approaches such as deep brain stimulation. Supplementary videos are available on Cambridge Core, accessible via the code printed inside the cover. This essential text bridges the gap in communication between experts in genetic-metabolic medicine and movement disorder neurology. With an emphasis on treatable conditions that should not be missed, this volume guides you through various disorders from a clinical, biochemical and genetic perspective.
