注意缺陷/多动障碍儿童临床特征与单胺类神经递质研究

目的：探讨注意缺陷/多动障碍（ADHD）儿童的临床特征及血清单胺类神经递质水平的变化。方法：对32例ADHD儿童（研究组）和46名正常儿童（对照组）测评Piers-Harris儿童自我意识量表（PHCSS）、儿童焦虑性情绪障碍筛查表（SCRED）、儿童冲动量表（BIS）等,对其中30例ADHD儿童及36名正常儿童测量血清5-羟色胺（5-HT）、多巴胺（DA）、肾上腺素等的含量。结果：研究组PHCSS评分低于对照组（P〈0.01）;研究组SCRED和BIS评分均高于对照组（P〈0.001）。研究组血清5-HT低于对照组（P=0.002）。血清5-HT水平与冲动总分（r=-0.273）呈负相关;血清DA水平与运动分呈正相关（r=0.541）。结论：ADHD儿童具有多动、冲动、自我意识低等临床特征。而血清5-HT水平降低可能与ADHD的冲动控制困难特征有关。

Study on clinical characters and serum levels changes of monoamine neurotransmitters in children with attention deficit hyperactivity disorder

Objective:To explore the clinical characters and serum levels changes of monoamine neurotransmitters in children with attention defecit hyperactivity disorder( ADHD). Method:32 ADHD children and 46 healthy children were recruited. They were evaluated with the Piers-Harris children's self-concept scale ( PHCSS) ,the screen for child related emotional disorder( SCRED) ,depression self-rating scale for cildren ( DSRSC) and Barratt's impulsivity scale( BIS). Their serum 5-hydroxytryptamine( 5-HT) ,dopamine( DA)...
