The Assessment of Movement Disorders Utilizing Live Two-Way Video

Extrapyramidal symptoms (EPS) and tardive dyskinesia (TD) are one of the most frequent and
troublesome adverse events when taking antipsychotic agents. The investigators aim in this
study to determine if the investigators can conduct examinations for EPS and TD remotely
using live two-way video. It is potentially beneficial for patients, especially those who
are located far away from psychiatrists if they could be seen by trained clinicians and
assessed for EPS and TD via two-way video in the future. Participants will be asked to have
a medical assessment which consists of simple questions and some examination of their
movements via two-way video and in person. The investigators will compare the results of
video examinations with the results of live examinations.
