Abstract:
Objective To investigate the change of event-related potentials(ERPs)N400 and its significances in children with Tic disorders.Methods N400 of 35 children with Tic disorders(case group)and 20 healthy children(control group)were taken.The results of case group and control group were compared with each other.Results N400 latency of the case group was(706.87?198.99)ms,and the amplitude was(26.12?13.64)?V;N400 latency of the control group was(485.75?85.76)ms,the amplitude was(22.35?19.76)?V.There was obvious difference in latency between two groups(P0.05).Conclusion ERPs N400 latency of children with Tic disorders prolong obviously which shows cognitive dysfunction in the patients.
