Tardive Dyskinesia
Pronunciation: TAR-div dis-ki-NEE-zhah
A neurological side effect of long-term antipsychotic medication use, characterized by involuntary, repetitive movements, particularly of the face, lips, and tongue.
Full Definition
Tardive dyskinesia (TD) is a serious iatrogenic movement disorder that can develop after months or years of antipsychotic treatment, particularly with first-generation medications. Symptoms include facial grimacing, lip smacking, tongue protrusion, and choreiform movements of extremities. The condition may be irreversible even after medication discontinuation, making early detection crucial. Modern clinical practice emphasizes regular monitoring using standardized assessment tools like the AIMS (Abnormal Involuntary Movement Scale). Documentation must clearly describe movement characteristics and timeline of symptom development in relation to medication history.
Usage
Usage note: Always spell out fully in formal documentation. May abbreviate as TD in progress notes after full term is established.
