Which of the following are symptoms of tardive dyskinesia?

• A. Headache
• B. Drooling and lip-smacking
• C. Rash
• D. Nausea

Answer: (B)

Tardive dyskinesia presents with involuntary, repetitive movements of the face, mouth, and tongue. Drooling and lip-smacking fit this pattern because they are involuntary mouth and jaw movements common in TD. Headache, rash, and nausea are not typical TD symptoms—they’re more general or relate to other conditions or medication side effects rather than the characteristic facial and oral movements TD produces. TD most often appears after long-term use of dopamine-blocking medications and can persist even after stopping the drug, so recognizing the distinctive facial/oral movements is key.
