Abstract:
Objective:To explore the correlation between white matter lesions (WML) at different locations and cognitive function.Methods:The cognitive function of 68 patients with WML in Beijing Electric Power Hospital from January 2019 to May 2020 were assessed with Montreal Cognitive Assessment Scale (MoCA), and the extent of WML were assessed with age-related white matter changes rating scale(ARWMCRs). Correlation between the ARWMCRs scores of different locations and the scores of all locations and the scores of cognitive function, as well as the relationship between the ARWMCRs scores of different locations and each subitem of cognitive function were analyzed.Results:In 68 patients with WML, the degree of lesions in different parts from heavy to light was frontal area, parietooccipital area, basal ganglia area and temporal area, and no white matter lesions were found in infratentorial area. Except the basal ganglia region, the ARWMCRs scores in other regions and the total score were negatively correlated with MoCA score, among which, the ARWMCRs score in left frontal area, right frontal area, left parietal pillow and right parietal pillow region had the strongest correlation with MoCA score( rs=- 0.388, - 0.479, -0.418, -0.502, all P<0.01).In WML patients, the left frontal area was negatively correlated with language, abstraction and orientation ( rs=- 0.479, - 0.324, - 0.288, all P<0.01).The ARWMCRs score in right frontal area was negatively correlated with visual spatial and executive function, memory, language, abstraction, and orientation ( rs=- 0.324, -0.272, -0.459, -0.382, -0.352, all P<0.05). The ARWMCRs score in left parietal occipital region was negatively correlated with visual spatial and executive function and memory ( rs =-0.287、- 0.270, all P<0.05). The ARWMCRs score in right parietal occipital region was negatively correlated with memory, language, abstraction and orientation ( rs=-0.366, -0.289, -0.260, - 0.307, all P<0.05).The ARWMCRs score in left temporal region was negatively correlated with language, abstraction and orientation ( rs=- 0.248, -0.372, - 0.608, all P<0.05).The ARWMCRs score in right temporal region was negatively correlated with abstraction and orientation ( rs=- 0.525, -0.465, all P<0.01).The ARWMCRs score in right basal ganglia was negatively correlated with orientation and memory ( rs=- 0.455, - 0.275, all P<0.01), while The ARWMCRs score in left basal ganglia was not correlated with MoCA subitems. Conclusions:The frontal area and parietal occipital area are the most serious lesions in WML patients, and the lesions in these two areas also cause the widest range of cognitive impairment.
