Abstract:
Objective:To examine the characteristics of oculomotor inhibition about children with attention deficit hyperactivity disorder(ADHD).Methods:Twenty-one children with ADHD according to the Diagnostic and Statistical Manual of Mental Disorder,4th edition(DSM-IV) and 21 matched controls were administered with fixation,prosaccade and antisaccade tasks.Results:(1) In the fixation task,the children with ADHD demonstrated significantly more intrusive saccade errors than the controls in either condition with distractors or without distractors[no distractors:(12.67±12.28) vs.(6.38±6.95),P=0.040;distractors:(16.91±10.00) vs.(11.29±5.99),P=0.030].(2) In the prosaccade task,there were no significant differences found between groups in saccadic parameters,in either gap condition or overlap condition.(3) In antisaccade task,the direction error rates of the ADHD group in either gap condition or overlap condition,were both higher than that of the control group[gap:(68.14±17.85) % vs.(54.10±20.22) %,P=0.020;overlap:(62.49±17.54) % vs.(49.27±17.21) %,P=0.020].Conclusion: It suggests that there is an abnormality of the oculomotor inhibition,which may be caused by abnormal structure and/or function of fronto-striatal in ADHD children.
