Impact of Heart Health on Dementia Risk in Type 2 Diabetes
Diabetes Prevalence and Health Risks
In 2024, an estimated 589 million adults globally were diagnosed with diabetes, with over 90% of these cases classified as type 2 diabetes. Research indicates that individuals with type 2 diabetes face an elevated risk of various health complications, including heart disease and dementia.
Study Findings on Heart Health and Cognitive Impairment
A recent study suggests that people with type 2 diabetes who adhere to the American Heart Association’s (AHA) ‘Life’s Essential 8’ guidelines for heart health may experience a reduced likelihood of developing mild cognitive impairment (MCI) and dementia. The research highlights the significance of maintaining optimal heart health in mitigating cognitive decline.
Increased Risk of Cognitive Decline
According to data from the International Diabetes Federation, those with type 2 diabetes are approximately 50% more likely to develop MCI and dementia, including Alzheimer’s disease and vascular dementia, compared to individuals with normal glucose levels. Yilin Yoshida, PhD, MPH, FAHA, a diabetes epidemiologist and assistant professor at Tulane University School of Medicine, emphasized the lack of effective therapeutic strategies to significantly diminish this risk.
Research Presentation and Future Implications
Yoshida is the lead author of the study presented at the American Heart Association’s Scientific Sessions 2025. The findings indicate that adhering to the AHA’s “Life’s Essential 8” recommendations may lower the risk of dementia, even for those genetically predisposed to these conditions. This study has not yet been published in a peer-reviewed journal, highlighting the need for further research in this area.
