Tardive dyskinesia is a neurological disorder caused by the
long-term use of neuroleptic drugs, or anti-psychotic medications.
Neuroleptic drugs are generally prescribed for psychiatric
disorders, as well as for some gastrointestinal and neurological
disorders. The prevalence of tardive dyskinesia is estimated to be
10 to 20 percent of individuals treated with anti-psychotic
medications. The elderly are more susceptible to persistent and
irreversible tardive dyskinesia than younger people.
Repetitive and involuntary movements characterize tardive
dyskinesia. Features of the disorder may include grimacing, tongue
protrusion, lip smacking, puckering and pursing, and rapid eye
blinking. Rapid movements of the arms, legs, and trunk may also
occur. Approximately 60 to 70 percent of the cases are mild, with
about 3 percent being extremely severe. Severe cases may involve
problems such as difficulty swallowing, speech interference,
cosmetic disfiguration, and respiratory trouble.
How is it treated?
There is no standard treatment for tardive dyskinesia. In many
cases the medication will be adjusted to use the lowest possible
dose, or discontinued if at all possible. Stopping the medication
is a gradual process, lowering the doses 10 to 25 percent every one
to three months. Replacing the neuroleptic drug with other
medications may help some patients. Other drugs such as
benzodiazepines, adrenergic antagonists, and dopamine agonists may
also be beneficial. Symptoms of tardive dyskinesia may remain even
after the medication is stopped. However, with careful management,
some symptoms may improve or disappear with time.
