Abstract
Chorea consists of continuous, unsustained, nonstereotyped movements of variably changing speed and direction that seemingly flow from one muscle group to another, thus giving the appearance of “dancing.” The differential diagnosis of chorea is large, consisting of many diseases and disparate causes (Table 25-1). Most causes of chorea are hypothesized to involve basal ganglia dysfunction. Physiologically, hypoactivity in the subthalamic nucleus and medial pallidum is thought to correlate with chorea.
