Abstract:
Objective To establish the normal parameters of psychometric measures such as the number connection tests A(NCT-A)and digit symbol tests(DST)in assessment of minimal hepatic en- cephalopathy(MHE).Methods One hundred and sixty healthy volunteers(aged 25 to 64 years;educa- tional level＞9 years)were divided into＜35 ys,35～44 ys,45～54 ys and 55～64 ys groups.All of the healthy volunteers were assessed with NCT-A and DST to establish the normal value of age-related parameters,which can be used for diagnosis of MHE in patients with liver cirrhosis.Two standard devi- ation of the normal mean was used as a diagnostic criterion for MHE.One hundred and six cirrhotic patients were assessed with these parameters.Results The parameters of NCT-A were(25.1?4.6) sec in＜35 ys group,(32.1?6.8) sec in 35～44 ys group,(38.6?7.1)sec in 45～54 ys group or (49.3?6.3)sec in 55～64 ys group.The scores of DST were 49.9?4.7 in＜35 ys group,44.6?4.8 in 35～44 ys group,38.5?5.0 in 45～54 ys group or 35.4?4.7 in 55～64 ys group.Thirty one out of 106 cirrhotic patients were diagnosed as MHE based on these parameters.Conclusion The NCT- A and DST are psychometric assessments for diagnosis of MHE.Age-based normal paramerters of NCT- A and DST are needed to be established.
