ARTICLE HIGHLIGHTS
Research background

Lacunes and glucose variability (GV) are gaining growing attention.

Research motivation

The association between GV, the severity of lacunes and the cognitive impairment in lacune patients with type 2 diabetes mellitus (T2DM) is still unknown.

Research objectives

To explore the correlation between GV, lacune burden and cognitive function in patients with lacunes complicated with T2DM.

Research methods

Seventy-two h continuous blood glucose monitoring was performed. The Montreal cognitive assessment was used to assess cognitive function. The burden of lacunes was evaluated using magnetic resonance imaging findings. Multifactorial logistic regression analysis was used to study the affecting the lacune load and cognitive impairment in patients. To predict the value of patients' cognitive impairment with lacunes complicated with T2DM, a receiver operating characteristic curve and a nomogram prediction model were constructed.

Research results

Standard deviation and percentage coefficient of variation (%CV) were the risk factors for an increased infarct burden in lacune patients complicated with T2DM. Time of range (TIR) is a protective factor. In addition, an increased SD, %CV were the risk factors for cognitive impairment in patients with lacunes complicated with T2DM. TIR is a protective factor.

Research conclusions

Blood glucose variability is closely associated with the level of lacune burden and cognitive dysfunction in lacune patients combined with T2DM. %CV, TIR have a certain predictive effect in cognitive impairment in lacune patients.

Research perspectives

Prospective studies are further needed to verify the results of this paper.
