What is chorea and how can it be treated?

Chorea is a condition in which the person has random, uncoordinated and uncontrolled movements. It looks like the person is fidgeting and restless. The muscles of the arms and legs are involved much more often than trunk or facial muscles. There are multiple underlying causes, such as from a hereditary disorder, brain injury, stroke, certain infections, or medication side effect. Finding a treatable underlying cause is the first step in management. Medications that can either deplete dopamine or block dopamine receptors can significantly improve symptoms.
