Objective:To explore the characteristics of attention during visual search tasks in adults with attention-deficit/hyperactivity disorder (ADHD).Methods:Totally 45 adult patients with ADHD who met the Diagnostic and Statistical Manual of Mental Disorders,Fourth Edition (DSM-IV) and 44 healthy controls matched with age,gender and IQ were selected.The reaction time and accuracy rate of two groups were compared under visual search tasks of low and high visual working memory load.Results:The reaction time was longer in patients with ADHD than in the healthy controls in both low-load task [(823 ± 144) ms vs.(754 ± 123) ms,P ＜ 0.01] and highload task [(912 ± 163) ms vs.(851 ± 162) ms,P ＜ 0.01].Compared with the performance in low load task,the search reaction time was longer in high load task [ADHD group:(823 ± 144) ms vs.(912 ± 163) ms,P ＜ 0.01;control group:(754 ± 123) ms vs.(851 ± 162) ms,P ＜0.01] and the accuracy rate was lower during high load task than low load task[ADHD group:(95.9 ±4.3)％ vs.(91.2 ± 14.29)％;control group:(95.8 ± 4.2)％ vs.(94.4 ±4.9) ％,P ＜ 0.01] in both ADHD and control groups.Conclusion:The results suggest impairment in top-down attentional control in ADHD adults.When the visual working memory load is increasing,ADHD patients allocate more working memory resources on storing the target representation and less resources on visual attention,so the search efficiency may be influenced.

Objective To explore the executive function profiles in adults with attention deficit hyperactivity disorder(ADHD)in a Chinese sample population. Methods We identified 68 outpatients fulfilling the diagnostic criteria for ADHD according to the Diagnostic and Statistical Manual of Mental Disorders-IV(DSM-IV)and 74 normal adults.All subjects completed clinical interview, Behavior Rating Inventory of Executive Function-Adult Version (BRIEF-A) and Cambridge Neuropsychological Test Automated Battery (CANTAB). Results ADHD group had higher scores in all factors of BRIEF-A questionnaire compared with normal control (P<0.01). ADHD group had a higher score in SWM strategy score [(30.84±5.58)vs.(28.80±5.85), t=2.056,P=0.042]compared with control group. Compared with control group, ADHD group had a lower score in RVP total hits [37(33,41.75) vs.3(37,48), Z=-3.184,P<0.01]. Total correct rejections[(508(497.5,518)vs. 516(503,529.5),Z=-2.229,P=0.0260)]were significantly lower,while RVP total misses were significantly higher [(17 (12.25,21)vs.12(7,20),Z=2.293,P=0.022)].ADHD-RS-IV attention deficit score was positively correlated with SWM strategy while RVP total misses were negatively correlated with RVP total hits and RVP correct rejections.Working memory score in BRIEF-A was significantly correlated with the SWM strategy,RVP total hits, RVP total correct rejections and RVP probable of hit as well as RVP total misses. Conclusion Adults with ADHD have executive functioning deficits which is correlated with ADHD core symptoms.
