Movement Disorders Presenting in Childhood.

PURPOSE OF REVIEW: This article provides an overview of movement disorders that present in childhood. Key clinical features are discussed, and a brief guide to management strategies is provided. Recent advances in the field of pediatric movement disorders are also a focus of the article.

RECENT FINDINGS: Advances in genetic technologies and cell biology have contributed greatly to the elucidation of underlying disease mechanisms in childhood movement disorders. This article discusses the expanding spectrum of both genetic and acquired movement disorders that present in childhood, including benign, acquired, genetic, and psychogenic movement disorders.

SUMMARY: Movement disorders in childhood comprise a wide spectrum of both genetic and acquired diseases, ranging from benign self-limiting conditions to more progressive phenotypes associated with significant morbidity and mortality. Elucidation of the underlying cause is achieved through accurate history, detailed clinical examination, review of video footage (including home videos), and, where appropriate, neuroimaging and laboratory investigations. Early accurate diagnosis will facilitate the instigation of appropriate management strategies.
