Abstract: Objective To explore the correlation between serum chemokine C-X3-C-motif ligand 1 (CX3CL1), also know as fractalkine (Fkn). levels and cognitive dysfunction in patients with white matter hyperintensity (WMH). Methods A total of 152 patients with cerebral small vessel disease (CSVD) enrolled in the First Affiliated Hospital of Xinxiang Medical University from March 2020 to August 2022 were collected. The general clinical data of patients, the routine sequence of cranial magnetic resonance imaging (MRI), biochemical indicators, serum CX3CL1 level, and Mini-mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) cognitive scores were collected, and the correlation between serum CX3CL1 levels and white matter hyperintensity and cognitive function was analyzed. Results A total of 152 participants were enrolled and divided into the group with normal cognitive function and the group of cognitive dysfunction according to the MMSE results, with the mean age of (59.60±8.84) years and (62.91±7.99)years, respectively. The correlation analysis results showed that CX3CL1 level and apparent space were negatively correlated with executive function, attention, and orientation.Regression analysis showed that CX3CL1 levels and white matter high-signal were risk factors for cognitive dysfunction. Receiver operating characteristic (ROC) curve analysis suggested that CX3CL1 levels may have potential predictive value for cognitive impairment. Conclusion Serum CX3CL1 levels and white matter hyperintensity are associated with cognitive function, and elevated serum CX3CL1 levels are risk factors for the development of cognitive dysfunction.
