[Objectives]
This study analyzes QEEG results in children with tic disorders, comparing those classified as “Heart Weak Children” with those who are not, according to the Five-Visceral Weak Children classification system in Korean medicine. By identifying shared characteristics and distinctions among these children, it seeks to enhance diagnostic consistency and establish a foundation for tailored treatments within Korean medicine. The findings aim to improve the accessibility and efficiency of Korean medicine treatment for children and adolescents.
[Methods]
This retrospective study analyzed data from 30 children with tic disorders, classified into Heart Weak and Non-heart Weak groups using the Five-Visceral Weak Children Questionnaire. QEEG data were examined based on z-scored fast Fourier transform (FFT) absolute power across electrodes and frequency bands. Independent samples t-tests were applied to assess differences and shared characteristics in brainwave activity, providing insights into potential subtypes within tic disorders.
[Results]
Significant differences in QEEG z-scored FFT absolute power were found between the Heart Weak and Non-heart Weak groups. Heart weak group showed clinically meaningful higher z-scores in the beta and high beta frequency bands, particularly in the frontal and central regions, suggesting elevated neurophysiological activity linked to psychological stress. In terms of commonalities, Both groups showed reduced activity and similar patterns in the delta band across electrode sites such as Fz, F4, C4, Cz, P3, and Pz, suggesting a potential association with non-restful brain states. Additionally, FWCQ results showed higher scores in Group A for items related to anxiety and emotional instability.
[Conclusion]
This study proposes that integrating the "Heart Weak Children" concept from Korean medicine with QEEG suggests the possibility of identifying subtypes within children with tic disorders. This approach facilitates a more objective interpretation of Korean medicine diagnostic methods and lays the groundwork for integrating modern and traditional medicine. However, limitations include a small sample size, absence of a healthy control group without tic disorders, potential bias from parent-reported data, and the need for improved artifact-removal techniques to enhance data reliability.
