Antipsychotic-induced tardive dyskinesia as a serious adverse effect in the psychopharmacotherapy of schizophrenia

Schizophrenia is a socially significant disorder with a high prevalence among young and middle-aged people. Movement disorders, or extrapyramidal syndrome, are potentially reversible antipsychotic-induced adverse effects (AEs) that stigmatize patients and worsen quality of life. Tardive dyskinesia (TD) is a neurological AE in the extrapyramidal system, which is accompanied by abnormal involuntary non-rhythmic choreiform or athetoid movements (hyperkinesis) that occur during the long-term use of antipsychotics. The reversible and persistent forms of TD are identified. The article analyzes the prevalence and predictors of TD, as well as the issues of its diagnosis.
