CLINICAL AND SOCIAL RISK FACTORS OF TARDIVE DYSKINESIA IN PATIENTS WITH SCHIZOPHRENIA DURING ANTIPSYCHOTIC TREATMENT

The purpose of the present work was to study the clinical features and risk factors of tardive dyskinesia among     the     schizophrenia     patients     who     durably     receive     the     antipsychotic     therapy. 180 of the 18 to 65 age bracket schizophrenia patients, who were treated in a residential psychiatric treatment facility, were examined with the use of the Positive and Negative Syndrome Scale (PANSS), Abnormal Involuntary Movement Scale (AIMS), and the basic chart of formalized sociodemographic and clinico-dynamic features developed at the Tomsk Mental Health Research Institute. The acquired data were processed by the Mann–Whitney U-Test and χ2. The average age of the tardive dyskinesia patients  turned out to be conclusively older than that of the patients without this derangement. People who have tardive dyskinesia statistically often happen to be single in comparison with other variants of marital status. It was found out that women happen to have tardive dyskinesia more often, which allows us to see the female gender as a risk factor. The tardive dyskinesia patients had certain negative symptoms. The patients were arranged into groups according to the prepotency of symptom-complexes over the subgroups: with orofacial, thoracolumbar and combined tardive dyskinesia. The average age of the orofacial dyskinesia patients turned out to be conclusively older than that of the patients without tardive dyskinesia. The negative symptoms level in the subgroup was conclusively higher than among those without tardive dyskinesia. The average age of the thoracolumbar dyskinesia patients was conclusively older than that of the patients without tardive dyskinesia. The average age of the combined dyskinesia patients was conclusively older than the patients without the tardive dyskinesia. The patients having schizophrenia for longer than 10 years prevailed in the combined dyskinesia group. Such characteristics as education level and social status, age of when the medical problem started, dominance of the positive symptoms, duration of antipsychotic agents administration, somatic condition, use of psychoactive substances, suicidal and hetero-aggressive behaviors make no contribution to the risk of tardive dyskinesia development in the presence of schizophrenia, and they are not protective factors either.
