ABSTRACT

Objective To explore the relationship of plasma norepinephrine (NE) and epinephrine (E) level with TCM syndrome differentiation of attention deficit hyperactivity disorder (ADHD) in children. Methods Plasma NE and E levels in 80 ADHD children (Group A) and 32 normal volunteers (Group B) were measured by the method of high performance liquid chromatography_electrochemical detectio n (HPLC_ECD). Among 80 ADHD children, 49 were differentiated with kidney_yin def iciency and liver_yang hyperactivity syndrome (Group A 1) and 31 with heart_sp leen deficiency syndrome (Group A 2). Results Plasma NE and E levels in Gro up A we re higher than Group B (P 0.05 ). Conclusion Hyperactivity and impulsi veness in ADHD children may be related with the high levels of plasma NE and E. The exc essively sympathetic excitement in ADHD with kidney_yin deficiency and liver_yan g hyperactivity syndrome is uncertain.
