Sophia Natriashvili

Despite the long period of scientific study of hyperkinesis in children it remains one of the most prominent challenge for contemporary neurologists. The aim of present paper is to estimate the role of computer electroencephalographic (EEG) findings in establishing the etiology, pathogenesis of tic disorders for prognozing the course of disease and choosing adequate therapy. 242 patients (194 males, 48 females) with various types of tic disorders in the age from 4 to 15 years old were investigated. 67 children were subjected to Quantitative EEG investigation, which revealed the different types of pathological patterns in 41 (61%) of cases. Obtained data gave us the possibilities to make some changes in produced chemotherapy and involve in treatment anticonvulsant (sodium valproat - Depakin). The improvement of clinical picture and course of disease and long remission was observed. This fact proves a practical importance of QEEG investigation in children with various types of tic disorders.
