Extrapyramidal symptoms (EPS) typically develop when?

• A. Within hours of starting therapy
• B. Within days
• C. After months to years and may be irreversible
• D. Only after dose increases

Answer: (C)

Extrapyramidal symptoms come from long-term blocking of dopamine receptors in the nigrostriatal pathway by antipsychotic meds. Among the various EPS, tardive dyskinesia stands out for its late onset and potential persistence. It typically develops after months to years of treatment and may be irreversible, even after stopping the drug. That’s why this option is the best choice: it captures the classic, time-delayed risk associated with prolonged antipsychotic exposure. Keep in mind that some EPS like acute dystonia or drug-induced parkinsonism can appear much earlier (hours to days or weeks), but these early-onset forms aren’t what’s most characteristic of EPS overall. Long-term risk factors include older age, higher doses, and longer treatment duration, which help explain the late emergence of tardive dyskinesia.
