There is increasing need for both consensus definitions and continued research into the causes, clinical spectrum, and treatment of pediatric movement disorders. Treatment has been largely based on experience rather than evidence because clinical trials are limited. With development of consensus definitions, identification of causative genes, understanding of the clinical spectrum of disease, and clinical trials, we can provide overall better care for children with movement disorders. This review highlights 5 areas where progress is being made to achieve these goals in pediatric movement disorders.
