Abnormal Movements and Movement Disorder Urgencies.

Abstract

Movement disorder urgencies present as an acute-to-subacute-onset primary movement disorder. Emergencies can lead to patient morbidity or mortality if not readily recognized. Many of these presentations have no standard diagnostic criteria or definitive laboratory tests, and thus relying on phenomenology is a clinician's best way to approach these challenging disorders. This section describes the phenomenology, presentation, complications, and management of movement disorder urgencies and emergencies.
