Abstract: Objective To explore the distribution of traditional Chinese medicine(TCM) constitution in children with attention deficit hyperactivity disorder(ADHD) (syndrome of heart and liver fire hyperactivity),and its relationship with symptoms and social function of the children.Methods A total of 70 children aged 7 to 14 years with ADHD (syndrome of heart and liver fire hyperactivity) were included in the study,who were treated in Yixing Traditional Chinese Medicine Hospital from January 2023 to May 2024.The TCM syndrome scoring,SNAP-Ⅳ and CGAS were used to evaluate the severity of the symptoms and the impact on social function of the children,and the TCM constitution distribution was divided according to the TCM constitution scale.Results TCM syndrome score was (18.54 ± 2.84) in ADHD children (syndrome of heart and liver fire hyperactivity).The average SNAP-Ⅳ score of the boys was (41.02±8.56),the average SNAP-Ⅳ score of the girls was (41.19±8.46),the average CGAS score of the boys was (63.12±6.83),and the average CGAS score of the girls was (63.75±6.65),which significantly affected the children′s social function and normal life activities; the severity of the disease was not related to gender(P>0.05).Unbalanced constitution was the main type of TCM constitution,totaling 42 cases (60%),and 28 cases (40%) were with balanced constitution.Among the children with unbalanced constitutions,the number of children with qi-stagnation constitution,yin-deficiency constitution and qi-deficiency constitution was the highest (≥10%); the children with yin-deficiency constitution had the longest course of disease ［(4.25±0.41) years］,and the children with balanced constitution had the shortest course of disease ［(1.74±0.33) years］.Conclusion The TCM syndrome score of the 70 children with ADHD(syndrome of heart and liver fire hyperactivity) in Yixing area included in this study is high,which has a significant impact on the social function of the children,but there is no gender difference.Unbalanced constitution is the main type in the distribution of constitution,and the disease course of ADHD (syndrome of heart and liver fire hyperactivity) is different in children with different constitutions.
