Recognizing Tardive Dyskinesia: An Interactive Video Glossary
Use this video glossary to explore real patient examples of tardive dyskinesia (TD), organized by body region and symptom presentation. Compare movement patterns across different areas of the body to build confidence in recognizing TD.

aFor the clinical diagnosis of TD, the offending agent must have been used for ≥3 months (or ≥1 month in individuals ≥60 years of age) and the movements must have been present for
≥4 weeks.2
bDIP often appears 2 to 4 weeks after initiating or increasing the dose of a DRBA, usually by 3 months.2
cRepetitive chewing movement, sometimes with lip smacking, pouting, opening/closing of the mouth, or tongue protrusion.8
dTypically manifested by repetitive rocking and swaying body movements.9
eTypically repetitive, stereotypic movements in the distal limbs (e.g., repetitive foot tapping, “piano-playing” finger and toe movements, and hand rubbing).8,9
fDRBA discontinuation or reduction can initially trigger or exacerbate TD that had been masked by DRBA treatment.10
gIncreasing the DRBA dose may diminish the chances of recovery from TD.10,11
