Abstract

Objective To explore the changes of attention cognitive function by studying Oddball task behavior and event-related potentials(ERPs) in children with first-episode tic disorder(TD). Methods Oddball task was tested in 30 children with TD and 30 normal children, and their behavioral data and P3a/P3b components of ERPs were analyzed. Results Children with TD had a lower hitting number (49(48, 50)) than control group (50(49, 50), P 0.05). Conclusion Attentional orienting is impaired in children with TD. Key words: Tic disorder; Oddball task; P300; P3a; P3b; Attention
