ABSTRACT
ObjectiveTo investigate the error monitoring and attention network in patients with obsessive-compulsive disorder (OCD).Methods 33 OCD patients and 31 healthy subjects were tested with the error monitoring task and attention network test.ResultsThere wcrc significant differences between the patients with OCD and heath controls on Full Correct(FC),Full Error(FE),the numbers of uncertain,the numbers of dropout in the error monitoring task ( FC ( 121.03 ± 4.41 ) / ( 135.61 ± 3.28 ),FE ( 19.30 ± 3.69 ) / ( 9.45 ± 2.33 ),the numbets of uncertain( 8.27 ± 2.16) / ( 2.87 ± 0.70),the numbers of dropout ( 13.70 ± 2.60 ) / (4.26 ± 1.24 ) ) (P ＜0.05 ).In the attention network test,the comparison between the patients with OCD and healthy subjects on the RT of the alerting network was significant differences (P ＜ 0.05 ).There was a significant correlation between attention network and error monitoring.ConclusionThe impairment of the error monitoring as well as attention network in patients with OCD may be involved in the dysfunction of anterior cingulate cortex.
