This condition is common in women, the elderly and people with manifestations of cognitive disorders, mood disorders. Predisposing factors for the onset of the disease include advanced age, brain damage, and previous electrotherapy.
Tardive dyskinesia may occur in 10 to 20% of patients taking antipsychotics for a minimum of 3 months to 1 year; or 1 month for patients over 60 years of age. The longer the medication is taken, the higher the risk.
Drug-induced tardive dyskinesia lasts at least 1 month, usually 3 to 6 months. This movement disorder usually occurs when the antipsychotic drug is suddenly stopped after taking the drug for a long time. Drugs that can cause this disorder include antipsychotics in the treatment of schizophrenia, bipolar disorder; antidepressants (Chlorpromazine, Fluphenazine,...); antiemetics such as prochlorperazine and metoclopramide, calcium channel blockers with dopamine receptor blocking properties such as flunarizine and cinnarizine.

4.Treatment of tardive dyskinesia Management of tardive dyskinesia usually includes:
Reducing dose or stopping current medication Switching to another antipsychotic or a different combination of drugs. Atypical antipsychotics such as olanzapine, risperidone or quetiapine are options when the patient is unresponsive to treatment. These drugs are effective in tardive dyskinesia, less likely to cause parkinsonism and restlessness. Clonazepam has been shown to be effective for the treatment of myoclonus. Clozapine is used in patients with chronic psychosis, but there is a risk of agranulocytosis and frequent monitoring of the blood count. Antioxidants such as vitamin E, vitamin B6, and Ginkgo biloba may also be effective in treating tardive dyskinesia. Ginkgo biloba has an antiplatelet effect, so special caution should be exercised in patients receiving anticoagulants or antiplatelet agents. Anticholinergics also work to prevent or reduce the severity of drug-induced dyskinesia. Some other drugs help relieve symptoms such as tetrabenazine, amantadine, propranolol.
