Which medication is listed for Tourette's syndrome?

• A. Risperdal
• B. Zoloft
• C. Seroquel
• D. Haldol

Answer: (A)

Tourette's symptoms respond to medications that dampen dopaminergic signaling in the brain’s motor pathways. Risperidone is an atypical antipsychotic that blocks D2 receptors (and also 5-HT2A receptors), which helps reduce both motor and vocal tics with a more favorable side-effect profile than older drugs. That combination of efficacy and tolerability makes it a commonly listed option for Tourette's syndrome. The other drugs don’t fit as primary tic treatments here: sertraline is an SSRI used for comorbid anxiety or OCD symptoms rather than tics; quetiapine can be used off-label but is less commonly listed as a standard tic treatment; haloperidol can reduce tics but carries a higher risk of extrapyramidal symptoms and other adverse effects.
