Abstract:
Objective To assess the application of Stroop color-word test ( SCWT) for screening of minimal hepatic encephalopathy (MHE) in patients with liver cirrhosis.Methods Sixty patients aged 18-65 years with liver cirrhosis and 60 age, education level-matched healthy subjects were examined with SCWT.The SCWT indexes were compared between two groups .MHE was identified when patients had abnormal number connection test-A (NCT-A) and/or digit symbol test (DST).Results Time consuming and errors of card 2, 3, 4 and Stroop interference effects ( SIE) reflecting word-interference and color-interference in SCWT were increased significantly in liver cirrhotic patients [(17.28 ±0.69)sec,(12.96 ± 1.10)sec, (30.30 ±1.40)sec, (5.00 ±0.90)sec, (13.74 ±1.22)sec, (0.36 ±0.10) times, (0.50 ± 0.11) times, (0.50 ±0.11) times, (5.00 ±0.90) times,(1.98 ±0.23) times, respectively] compared to those in healthy subjects [(10.18 ±0.57) sec,(7.68 ±0.39)sec,(15.68 ±0.33)sec,(1.94 ±0.37) sec, (6.56 ±0.70)sec, (0.02 ±0.02) times,(0.10 ±0.04)times,(0.10 ±0.04)times,(0.04 ±0.02) times,(0.20 ±0.08) times, respectively; t =12.95, 6.98, 8.19, 7.02, 11.91, 10.09, 8.97,8.15, 17.94,11.37,all P=0.00];while there were no significant differences in time consuming and errors of card 1 between liver cirrhotic patients [ ( 7.10 ±0.40 ) sec and ( 0.04 ±0.03 ) times ] and healthy subjects [(6.72 ±0.36)sec and (0.02 ±0.02) times; t=1.89, 1.91, both P=0.06].The sensitivity of word SIE, color SIE and word SIE +color SIE of SCWT for primary screening of MHE was 0.83(50/60), 0.88 (53/60) and 0.98(59/60) respectively, whereas the specificity was 0.87(52/60), 0.80(48/60) and 0.83(50/60) respectively.ConclusionThe SCWT may serve as a convenient , effective and reliable tool for primary screening MHE.
