Lay Summary

Tardive dyskinesia is a rare side effect of antipsychotics. This disorder is characterized by involuntary movements typically of the facial region, but also other body parts. These movements begin only after a longer exposure to antipsychotics, and are thus not necessarily seen in the clinical registration trials. However, in long-term trials, such as phase 3 or 4 trials, subjects are more likely to be identified. While old antipsychotics caused this side effect in up to one fifth of long-term treated subjects, newer antipsychotics show much lower rates. However, the exact frequency of these rare cases for each specific second generation antipsychotic is not known. In our study, we aim to summarize and meta-analyze the frequencies and severities of tardive dyskinesia during clinical trials with second generation antipsychotics.
