[Study on correlation between neuropsychological features and Chinese medical syndrome types in patients with Wilson's disease].

ABSTRACT

OBJECTIVE: To explore the correlation between neuropsychological features and Chinese medical syndrome types in Wilson's disease (WD) patients, thus providing evidence for early intervention by syndrome typing. METHODS: Totally 96 WD patients were assigned to Gan-Dan damp-heat syndrome (GDDHS, 31 cases), Gan-Shen yin deficiency syndrome (GSYDS, 47 cases), and qi-blood deficiency syndrome (QBDS, 18 cases) by syndrome typing. Three items of neuropsychological testing were performed in them, i.e., Raven's standard progressive matrices (R'SPM), Stroop color-word test (CWT), trail making test (TMT). The correlations between the integrals of Chinese medical syndrome types and results of the 3 tests were analyzed. RESULTS: (1) There was statistical difference in the total scores of R'SPM, the word interference time of CWT, and interference effects of TMT among the 3 syndrome types (P <0.01, P <0.05). There was statistical difference in the total scores of R'SPM and the word interference time of CWT in patients of QBDS, when compared with those of GDDHS and GSYDS (P <0.05). There was statistical difference in interference effects of TMT in patients of GDDHS, when compared with those of QBDS and GSYDS (P <0.05). (2) The integrals of the 3 syndrome types were negatively correlated with the total scores of R'SPM (P <0.01). The integral of GDDHS was significantly positively correlated with the interference effects of TMT (P <0.01). The integral of GSYDS was significantly positively correlated with TMT-B time consumption and interference effects of TMT (P <0. 05). The integral of QBDS was significantly positively correlated with the word interference time of CWT (P <0.05). CONCLUSIONS: There was correlation between neuropsychological changes of WD patients and Chinese medical syndrome types. The severity of asthenia syndrome was sequenced from high to low as QBDS > GSYDS > GDDHS. The severity of asthenia was higher than that of asthenia.
