According to many studies, elderly female patients appear to be particularly susceptible to the development of TD. In a 2009 study of 227 inpatients with schizophrenia, the researchers studied the prevalence and risk factors associated with TD among Filipino patients with schizophrenia admitted to a mental health facility. The mean patient age was 40 (range: 19-73 years). Patients had a mean disease duration of 6 years, took a daily antipsychotic dose of 700 mg in chlorpromazine equivalent, and had a lifetime neuroleptic exposure of at least 5 years.

TD prevalence rate was 20.3% (46 out of 227 patients). TD was noted more in females and older age groups.
