Tardive dyskinesia rates with atypical antipsychotics in older adults.

Tardive dyskinesia is a chronic drug-induced movement disorder that tends to be persistent in older adults who are treated with antipsychotics. Tardive dyskinesia can affect older patients both physically and psychologically, leading to frequent falls, difficulty eating, and depression. While atypical antipsychotics may cause tardive dyskinesia, the percentage is usually significantly lower than with conventional antipsychotics. Using atypical antipsychotics, particularly at lower doses, may aid in preventing symptoms of tardive dyskinesia in older adults.
