Heart disease, strokes and diabetes contribute to many dementia cases in the United States, but the risk is not equal everywhere, a new study says. Overall, more than a third (37%) of U.S. dementia cases are linked to eight conditions: diabetes, heart failure, atrial fibrillation, coronary artery disease, heart attack, stroke, high blood pressure and high cholesterol, researchers found. The South has the strongest link between these diseases and dementia, researchers reported recently in the journal Alzheimer’s & Dementia. “A substantial number of dementia cases could be eliminated by mitigating modifiable cardiometabolic risk factors, especially in U.S. counties with a high risk of dementia attributed to these risk factors,” senior researcher Dr. Brad Racette said in a news release. He’s chair of neurology at Barrow Neurological Institute in Phoenix. For the study, researchers analyzed claims data from Medicare covering nearly 21 million Americans 67 and older, including more than 756,000 dementia cases. Dementia cases were most strongly associated with stroke, with a 2.2-times higher risk, followed by heart failure (2.1 times increased risk) and high blood pressure (78% increased risk), results show. The link between high cholesterol and dementia was the weakest, with a 27% increased risk, researchers found. “Realistically, a 15% proportional reduction in these [eight] risk factors would reduce incident dementia cases in the population by an estimated 6.3 %,” Racette estimates.
