What Is Tardive Syndrome?
Tardive dystonia involves involuntary movements and muscle contractions characterized by twisting into sometimes painful positions, such as head tipping back or trunk arching. Tardive dystonia tends to have a younger mean age of onset than tardive dyskinesia.
Tardive tremors involve shaking movements usually in the hands or arms, they but can also affect the legs, feet, and head. People with tardive tremors may also have voices that sound shaky.
Tardive tics involve brief motor or muscle movements or vocal sounds that occur involuntarily and repeatedly.
