Purpose of review To provide an update on tardive dyskinesia rates in patients treated with first-generation or second-generation antipsychotics in studies published since the last systematic review in 2004.

Recent findings Across 12 trials (n = 28 051, age 39.7 years, 59.7% male, 70.9% white, followed for 463 925 person-years), the annualized tardive dyskinesia incidence was 3.9% for second-generation antipsychotics and 5.5% for first-generation antipsychotics. Stratified by age, annual tardive dyskinesia incidence rates were 0.35% with second-generation antipsychotics in children, 2.98% with second-generation antipsychotics versus 7.7% with first-generation antipsychotics (P < 0.0001) in adults, and 5.2% with second-generation antipsychotics versus 5.2% with first-generation antipsychotics (P = 0.865) in the elderly (based almost exclusively on one retrospective cohort study). In four adult studies (n = 2088, age 41.2 years, 71.2% male, 62.0% white), tardive dyskinesia prevalence rates were 13.1% for second-generation antipsychotics, 15.6% for antipsychotic-free patients, and 32.4% for first-generation antipsychotics (P < 0.0001).

Summary Current evidence supports a lower tardive dyskinesia risk for second-generation antipsychotics than for first-generation antipsychotics. Tardive dyskinesia incidence was higher with second-generation antipsychotics than previously reported, possibly due to recent studies with relatively short mean durations and use of nonstandard tardive dyskinesia definitions.
