Tardive dyskinesia /ˈtɑrdɨv ˌdɪskɨˈniːʒə/ is a difficult-to-treat form of dyskinesia, a disorder resulting in involuntary, repetitive body movements. In this form of dyskinesia, the involuntary movements are tardive, meaning they have a slow or belated onset. This neurological disorder frequently appears after long-term or high-dose use of antipsychotic drugs, or in children and infants as a side effect from usage of drugs for gastrointestinal disorders.
