Tardive dyskinesia (TD) is a potentially permanent side effect of drugs used to control schizophrenia and other psychoses. This late-developing (tardy, or tardive) complication consists of annoying, mostly uncontrollable movements (dyskinesias). Typical symptoms include repetitive sucking or blinking, slow twisting of the hands, or other movements of the face and limbs. TD can cause tremendous social embarrassment to particularly vulnerable individuals. Several different theories have been proposed for the development of TD. 1 According to one, long-term treatment with antipsychotic drugs causes the brain to become overly sensitive to the neurotransmitter dopamine, resulting in abnormal movements. According to another, imbalances among different neurotransmitters can cause or aggravate symptoms. In a third theory, TD may arise in part from damage to the brain caused by free radicals generated by schizophrenia treatments. All of these theories may contain some truth. Unfortunately, discontinuing medication that caused TD usually doesn’t help, and may even worsen the dyskinesia as well as the underlying schizophrenia. 2 Drugs such as L-dopa and oxypertine may improve TD but present their own significant risk of side effects. Fortunately, newer medications for schizophrenia that are less likely to cause TD have been developed in recent years.
