Stereotypies, along with tics, are the most common hyperkineses, especially among children. It has been esTableished that stereotypies can occur among children with normal development. At the same time, we found only one article on the prevalence of stereotypies among relatively healthy adults. The aim of the study is to assess the prevalence and nature of stereotypies among adults without neurological and intellectual disorders and to determine its relationship with tics and associated psychiatric symptoms. Material and methods. We have created an online questionnaire that includes 32 questions about the presence of movement disorders and their characteristics, assessment of anxiety, depression and attention level. 80 people were studied, including 21 men and 59 women, the median age was 23.0 [22.0; 26.0] years. The results of the study. Of the 80 people who participated in the study, signs of stereotypies, motor and/or vocal tics were identified in 60 people (75%). Each of them had from 1 to 15 symptoms (median – 3.5 [3.0; 6.0]). In 59 (73.8%) people, the revealed motor symptoms were regarded as stereotypies, in 10 (12.5%) people – motor tics, in 6 (7.5%) – vocal tics. In 4 people (5.0%), motor tics were combined with vocal tics, which is typical for Tourette's syndrome. Participants with violent movements were more likely to have a high level of anxiety (53.3% vs. 10%), which often indicated obsessive-compulsive symptoms (41.7% vs. 15.0%), and they also performed worse on the Schulte Table test (40.0 sec vs. 31.5 sec). In-person examination of respondents demonstrated a high level of sensitivity and specificity of the questionnaire in relation to stereotypies (100% and 66.7%, respectively), but a low level of sensitivity to tics (33.3%) with 100% specificity. Conclusion. Stereotypies are quite common among the adult population, even in the absence of organic brain damage and cognitive decline, and in about half of the cases they are combined with obsessive-compulsive symptoms and anxiety.
