Drug induced dyskinesia
is an involuntary movement disorder. Signs and symptoms include repetitive and irregular motions of the mouth, face, limbs and/or trunk.
Treatment with antipsychotic drugs
(commonly used to treat Parkinson disease
) are well recognized causes of drug-induced dyskinesia.
Dyskinesia develops in around 40% of people with Parkinson's disease who have been on levodopa treatment for four to six years. Tardive dyskinesia
is a severe form of drug-induced dyskinesia due to antipsychotic treatments. Tardive dyskinesia develops in 5% of people per year of treatment.
