Abstract:
Objective To compare the clinical value of three visual rating scales (VRS) for white matter lesions (WML) in Alzheimer's disease (AD) and mild cognitive impairment (MCI).Methods Totally 184 subjects (including 107 AD patients,47 MCI patients and 30 normal controls)were recruited.All subjects underwent comprehensive neuropsychological tests and were examined with a standard protocol of MR imaging.WML burden was rated with the Age-Related White Matter Changes (ARWMC) rating scale,Cholinergic Pathways Hyperintensities Scale (CHIPS) and Fazekas scale.Consistence of the three rating scales were analyzed,and detection results of WML in AD/ MCI/NC group with the three rating scales were compared.The relationship between WML and cognitive function in AD and MCI groups were explored.Results ARWMC rating scale,CHIPS and Fazekas scales were moderately to highly correlated with WML (r=0.61-0.78,all P＜0.01).ARWMC showed that WML were in the left and right frontal lobes in AD and MCI groups and in the right frontal lobe and left temporal lobe in NC group,which had significant differences (F=4.20,4.69,4.69,3.36,respectively,all P＜0.05).WML in the left temporal lobe had a significant difference between MCI group and NC group (F=3.36,P＜0.05).CHIPS showed that WML in the front left side of centrum semiovale in AD and MCI groups had significant difference as compared with that in NC group (F=4.88,P＜0.05),and WML in the rear right side of low external capsule had a significant difference between AD and NC groups (F=3.04,P＜0.05).Fazekas scale showed that there was no difference in WML among AD,MCI and NC groups.ARWMC showed that scores of WML in right temporal lobe were positively correlated with concentration and visual construction,and bilateral basal ganglia were negatively correlated with the concentration.Fazekas scale showed that scores of WML in periventricular were negatively correlated with concentration,MMSE and orientation,scores of WML in deep white matter were negatively correlated with concentration,abstraction and judgment,and the whole scores were negatively correlated with concentration.CHIPS showed that the scores of WML in the rear left side of low external capsule were negatively correlated with short-term memory in MCI group.Conclusions The three rating scales well consistent with each other.ARWMC rating scale and CHIPS can detect the differences in WML between AD,MCI and NC groups.The scores of CHIPS in WML are related with cognition in MCI group,while scores of ARWMC and Fazekas scale in WML are correlated with many aspects in cognitive function in AD group.In general speaking,CHIPS in MCI patients and ARWMC rating scale in AD patients show more advantages in the detection of WML and have better correlation with cognitive function.
