The completed portions of the MIND-TD Questionnaire that accompany this video are taken from sections of the questionnaire and do not represent the screening tool in its entirety.


The MIND-TD Questionnaire is intended to facilitate a dialogue about abnormal movements with patients at risk for TD. Diagnosis of TD should be based on the patient’s medical history, their symptoms, and the clinician’s best judgment.
