Data collection was taken on January to May 2020 using medical record data for glycated hemoglobin (HbA1c) levels (cut off score 7%) and Montreal Cognitive Assessment ver. Indonesia (MoCA-Ina) score (cut off score 26) to evaluate the cognitive function. Statistical bivariate analysis performed using chi-square and multivariate analysis covariate variables using logistic regression. Results: Uncontrolled diabetes mellitus as shown by a high HbA1c level were significantly increase the risk of cognitive decline. The study showed a significant relationship between HbA1c levels with cognitive function (OR=5,98; CI 95% 2,25-15,58; p=0,000). A logistic regression analysis of various cognitive functions showed that memory was the most affected domain in patient with uncontrolled type 2 diabetes.
