Abstract:

Objective To explore the correlation between total cerebral magnetic resonance imaging (MRI) burden and cognitive function in patients with cerebral small vessel diseases (CSVDs). Methods A total of 227 CSVD patients diagnosed by the brain MRI and hospitalized in the Department of Neurology from September 2021 to October 2022 were recruited. Their clinical data, brain imaging data, and hematological indicators were collected. Cognitive function was evaluated using the Montreal Cognitive Assessment (MoCA) scale. The correlation between MRI markers and cognitive dysfunction was explored. Results The multivariate analysis showed that age, hypertension, homocysteine (HCY), uric acid (UA), lacunar stroke score (Lac) and total burden of CSVDs were all significantly correlated with the MoCA score ( P<0.05). When other variables remained unchanged, the MoCA score decreased by 2.27 points for each point increase in the total burden of CSVD. The MoCA score decreased by 0.74 points for each point increase in the Lac score. The MoCA score decreased by 0.94 points for patients with a history of hypertension compared with those lacking the history of hypertension. The MoCA score decreased by 0.01 points and 0.07 points for each unit increase in UA and HCY levels, respectively. The MoCA score decreased by 0.07 points for one year older. Overall, all predictors explained the 55.1% decrease in MoCA scores. Conclusion The cognitive function of CSVD patients is affected by many factors, and the brain MRI visualizes the intracranial pathological state. It is suggested that the total burden of brain MRI has an early warning significance for cognitive decline.
