Full Definition
Tardive dyskinesia is a potentially irreversible neurological condition characterized by repetitive, involuntary movements of the face, tongue, lips, and extremities. It typically develops after months or years of antipsychotic medication use, particularly with first-generation neuroleptics. The condition presents significant medico-legal implications and requires careful risk-benefit assessment in long-term psychiatric treatment planning. Early recognition and intervention are crucial for optimal patient outcomes.
