The issue of bullying prevention remains extremely urgent due to persistence of this social phenomenon in educational institutions. The paper reports a clinical case of the long functional neurological disorder in an adolescent female patient. The patient M.’s mental status at admission was determined by frequent manifest recurrent convulsive attacks with the prolonged loss of consciousness developed against the background of systematic bullying. The clinical features of the systematic attacks observed could indicate the disorder epileptic genesis. However, the series of laboratory and instrumental tests combined with consulting experts in psychiatry confirmed the somato-mental origin of convulsive conditions. Thus, it can be concluded that not every seizure syndrome is necessarily a manifestation of a neurological disorder. The reported example emphasizes the importance of preventing bullying in educational institutions, as well as raising awareness of individuals involved in the educational process about possible consequences of bullying in educational institutions and the importance of creating a comfortable and safe psychological environment.
