Summary
Chorea is a state of excessive, spontaneous movements, irregularly timed, non-repetitive, randomly distributed, and abrupt in character. The severity of movements may vary from restlessness with mild intermittent exaggeration of gesture and expression, fidgeting movements of the hands, and dance-like gait to a continuous flow of disabling violent movements. The pathogenesis of chorea is mainly related to striatal dysfunction. The classification of the causes of choreatic dyskinesias is complex and involves many clinical entities, both hereditary and acquired. The severity of chorea can be reduced by antipsychotics, tetrabenazine or benzodiazepines.
