New Study: Good Heart Health Can Slash Dementia Risk in Diabetics
A new study, part of the UK Biobank project, has found that maintaining good cardiovascular health can significantly reduce the risk of mild cognitive impairment (MCI) and dementia in those with type 2 diabetes. The research, led by the Karolinska Institute in Sweden, suggests that following the American Heart Association's 'Life's Essential 8' metrics could help prevent these conditions.
The study, published in the journal Neurology, found that among those with a high genetic risk for dementia, maintaining moderate-to-high cardiovascular health lowered MCI risk by 27% and dementia risk by 23%. Remarkably, even those with low cardiovascular health saw a 15% reduction in MCI and dementia risks compared to those with the lowest heart health scores.
The research builds on previous findings that people with type 2 diabetes have a 50% higher risk of MCI and dementia than those with normal glucose levels. The new study suggests that achieving optimal heart health can mitigate this increased risk. The 'Life's Essential 8' metrics include measures like blood pressure, cholesterol, blood sugar, and body mass index. The study also found a positive association between better heart health scores and larger brain volume, a marker of healthier brain aging.
With over 589 million adults worldwide living with diabetes, the majority being type 2, these findings offer a promising avenue for prevention. The study underscores the importance of maintaining good cardiovascular health, even in those at higher risk, to potentially reduce the risk of cognitive decline and dementia.
