Tardive dyskinesia (TD) is an involuntary neurological movement disorder caused by the use of dopamine receptor blocking drugs that are prescribed to treat certain psychiatric or gastrointestinal conditions. Long-term use of these drugs may produce biochemical abnormalities in the area of the brain known as the striatum. The reasons that some people who take these drugs may get tardive dyskinesia, and some people do not, is unknown. Tardive dystonia is a more severe form of tardive dyskinesia in which slower twisting movements of the neck and trunk muscles are prominent.
Signs & Symptoms
Tardive dyskinesia is characterized by involuntary and abnormal movements of the jaw, lips and tongue. Typical symptoms include facial grimacing, sticking out the tongue, sucking or fish-like movements of the mouth. In some cases, the arms and/or legs may also be affected by involuntary rapid, jerking movements (chorea), or slow, writhing movements (athetosis). Symptoms of tardive dystonia include slower, twisting movements of larger muscles of the neck and trunk as well as the face.
Tardive dyskinesia is caused by long-term use of a class of drugs known as neuroleptics. Neuroleptic drugs are often prescribed for management of certain mental, neurological, or gastrointestinal disorders. Metoclopramide and prochlorperazine are drugs used for chronic gastrointestinal conditions that may cause tardive dyskinesia. Neuroleptic drugs block dopamine receptors in the brain. Dopamine is a neurotransmitter which is a chemical that helps brain cells to communicate. Although most cases occur after a person has taken these drugs for several years, some cases may occur with shorter use of neuroleptic drugs.
Tardive dyskinesia affects individuals who have been taking neuroleptic drugs for a long period of time. A high percentage of schizophrenic people who have spent long periods of time taking these drugs have a high risk of developing TD. However, neuroleptic drugs are also prescribed for depression, some digestive disorders, and other neurologic illnesses.
Treatment of tardive dyskinesia initially consists of discontinuing the neuroleptic drug as soon as involuntary facial, neck, trunk, or extremity movements are identified in people taking neuroleptic drugs if this is felt to be safe psychiatrically. Use of an “atypical” neuroleptic drug is often used in place of traditional neuroleptics if felt to be psychiatrically appropriate. However, the “atypical” neuroleptic drugs are also capable of causing or perpetuating tardive dyskinesia. In some cases, physicians may be forced to reinstitute a neuroleptic drug if the tardive dyskinesia symptoms do not disappear and become very severe after medication is discontinued.
In 2017, Ingrezza (valbenazine) was FDA approved to treat adults with tardive dyskinesia. Ingrezza is manufactured by Neurocrine Biosciences, Inc.
In 2017, Austedo (deutetrabenazine) was FDA approved for the treatment of tardive dyskinesia in adults. Austedo is manufactured by Teva Pharmaceutical Industries Ltd.
Studies are ongoing to determine possible new drug therapies for the treatment of tardive dyskinesia. Choline, lithium, bromocriptine, baclofen, methyldopa, valproate, clonidine, propranolol, amantadine, clonazepam, and nifedipine have occasionally been helpful but in most cases do not improve dyskinesia. Tetrabenazine is often useful for symptomatic treatment of tardive dyskinesia and is currently available for use in the US. However, it carries the risk of causing or aggravating depression. Other experimental drugs are being tested to reduce or eliminate the symptoms of tardive dyskinesia.
