Tardive Dyskinesia

Overview, Causes, & Risk Factors | Symptoms & Signs | Diagnosis & Tests | Prevention & Expectations | Treatment & Monitoring

Tardive dyskinesia is a movement disorder that occurs as a side effect of treatment with certain medications.

What is going on in the body?

Neuroleptic drugs, such as haloperidol, thioridazine, and chlorpromazine, sometimes called antipsychotics or tranquilizers, are used to treat many different psychiatric conditions. These drugs help people with psychosis and agitation. They are also useful for certain other neurologic problems, nausea, dizziness, and other conditions. A side effect of these drugs is abnormal movements. This side effect usually happens after the responsible drugs have been used for a long time. The exact reason for the development of this condition is not known.

What are the causes and risks of the condition?

The use of neuroleptic drugs may cause this condition. It is considered a possible side effect of these drugs.

The primary risk of this condition is that it may not go away. The movements may be embarrassing and cause mental anguish. The more advanced the condition, the less likely it is to go away.
