[Genetic features of EEG abnormality in children with Tourette syndrome].

ABSTRACT

OBJECTIVE: To investigate the biogenetic significance of EEG abnormality in Children with Tourette syndrome (TS) and their parents. METHODS: EEG monitoring was carried out for 2 hours in 25 children with TS and their parents. RESULTS: The rate of EEG abnormality was significantly higher than the incidence of tic disorders in parents of TS children. The rate of abnormal EEG in parents of TS children with abnormal EEG was significantly higher than that in parents of TS children with normal EEG. EEG abnormality had no significant differences in parents of males and those of females. CONCLUSION: EEG examination further indicates that Tourette syndrome has an inherit able tendency.
