Movement disorders such as dyskinesias and Sydenham's chorea are treated with which medication?

• A. Haloperidol
• B. Risperidone
• C. Chlorpromazine
• D. Trifluoperazine

Answer: (A)

Blocking dopamine receptors with a potent antagonist helps control hyperkinetic movements like chorea. Haloperidol is a classic, high-potency D2 receptor antagonist with strong and well-established efficacy in chorea, including Sydenham chorea, because it dampens dopaminergic signaling in the basal ganglia that drives these involuntary movements. While other antipsychotics can also block dopamine receptors, haloperidol’s potency and track record make it the preferred choice for acute and effective control of choreiform movements. Keep in mind that all antipsychotics can cause movement-related side effects with longer use, so monitoring is important.
