Pronunciation: TAR-div dis-kih-NEE-zhah
Late-onset movement disorder caused by prolonged use of dopamine-blocking medications.
Full Definition
Tardive dyskinesia is a potentially irreversible neurological side effect that can develop after months or years of treatment with antipsychotic medications or other dopamine receptor blocking agents. It is characterized by involuntary, repetitive movements, typically affecting the face, lips, tongue, and sometimes limbs. The condition poses significant clinical and ethical considerations in psychiatric treatment, requiring careful monitoring and informed consent discussions. Documentation should include detailed descriptions of abnormal movements and their impact on function.
