Treatable Movement Disorders of Infancy and Early Childhood

Movement disorders in childhood can be difficult to diagnose early. Disease processes present variably and can mimic each other. It is particularly important to remain vigilant for the subset of these movement disorders that are treatable. These disorders can be managed with (1) treatments specific to the disease that substantially reduce symptoms; (2) treatments that can prevent progression; (3) treatments that can hasten recovery; or (4) surveillance and management of the associated, sometimes life-threatening, comorbidities. Here, we present a practical and phenomenology-oriented framework for diagnosing and managing these treatable movement disorders of infancy and early childhood.
