tardive dyskinesia
Pronunciation: TAR-dive dis-kih-NEE-zhah
Potentially irreversible movement disorder characterized by involuntary movements, typically caused by long-term antipsychotic medication use.
Full Definition
Tardive dyskinesia is a serious neurological side effect that can develop from prolonged use of antipsychotic medications, particularly typical antipsychotics. It manifests as involuntary, repetitive movements most commonly affecting the face, lips, tongue, and extremities. The condition may be irreversible even after discontinuation of the causative medication, though early detection and intervention can improve outcomes. Risk factors include older age, female gender, diabetes, and duration of antipsychotic exposure. Regular monitoring using standardized assessment tools like the AIMS scale is essential for early detection and prevention strategies.
Usage
Usage note: Note the spelling 'dyskinesia' not 'dyskinesis.' Often abbreviated as 'TD' in clinical notes.
