Hyperkinetic movement disorders (HMDs) are characterized by the presence of excessive, abnormal, and involuntary movements and can be isolated or a sign of another underlying neurologic condition. They can result from autoimmune disorders, infections, genetic diseases, drug-related causes, or functional disorders, but in many cases, they are identified as idiopathic. The numerous possible causes of HMDs make the diagnostic process challenging and can cause delays that may be detrimental to treatable disorders. Therefore, an early and accurate diagnosis is of utter importance as it has significant implications for treatment. The identification of various genetic causes and the subsequent integration of genetic testing in clinical practice has significantly impacted the management of HMDs.

In this podcast, Sanjay Pandey, MD, Govind Ballabh Pant Hospital, New Delhi, India; Carlo Colosimo, MD, FEAN, Santa Maria University Hospital, Terni, Italy; and Marcelo Kauffman, MD, PhD, Hospital JM Ramos Mejia, Buenos Aires, Argentina, will discuss the latest updates in the classification and management of HMDs, including iatrogenic disorders, and will also cover the emerging role of genetic testing.
