Guide To Diagnosing, Preventing, And Treating Tardive Dyskinesia

Tests For Other Movement Disorders

An individual experiencing symptoms of tardive dyskinesia may need to undergo tests for other movement disorders. Their doctor uses a process of elimination before they can make a tardive dyskinesia diagnosis. Doctors may use imaging tests like CT scans, x-rays, MRIs, genetic testing, an electroencephalogram, and metabolic testing to eliminate cerebral palsy or a stroke as the cause of the patient's symptoms.

In-depth genetic tests on an individual's blood sample can dismiss Huntington's disease. A doctor may use a single-photon emission CT test and a dopamine transporter scan to rule out Parkinson's disease. Doctors can rule out Tourette's syndrome from the possible causes through a thorough medical history and physical exam.
