Vascular Health Risk Factors Increase Dementia Risk: Research Findings
Taking care of your blood vessels is essential for maintaining a healthy body and brain. There are several things you can do to keep your vascular system in tip-top shape. For starters, avoiding smoking and keeping your blood pressure and blood sugar levels under control can significantly reduce your risk of developing vascular diseases.
Recently, a study published in the Journal of the American Heart Association found a link between certain midlife vascular risk factors, such as high blood pressure, diabetes, and smoking, and the risk of developing dementia. The study found that these risk factors were more prevalent in female, Black, and non-carriers of the APOE ε4 gene, which is associated with an increased risk of developing Alzheimer's disease.
The study analyzed medical data from about 7,700 participants from the Atherosclerosis Risk in Communities (ARIC) study, which ran from 1987–2020 with a 33-year follow-up. Researchers found that between 22–44% of dementia cases in the participants were attributable to midlife and late-life vascular risk factors.
"The burden of dementia remains high," said Jason R. Smith, PhD, lead author of the study. "It has a heterogeneous presentation and pathology, so targeting risk factors that are modifiable, more proximal to dementia expression (including hypertension, diabetes, and smoking), and that could potentially impact more than one underlying process giving rise to dementia, is paramount to reduce population-level dementia risk."
So, how does maintaining good vascular health help keep your brain healthy? High blood pressure and vascular disease can damage the small vessels that supply the brain, leading to chronic ischemia and brain tissue damage. Vascular risk factors promote inflammation and free radical damage, contributing to neurodegeneration and the development of Alzheimer's disease. Chronic vascular dysfunction can also make the blood-brain barrier leaky, allowing harmful substances to enter the brain and accelerate neuronal damage.
Overall, the study reinforces the increasingly clear message that vascular health is brain health. "My first reaction was that the findings were both striking and practical - nearly half of dementia cases by age 80 could be linked to modifiable vascular risk factors like high blood pressure, diabetes, and smoking," said Christopher Yi, MD, a vascular surgeon. "It's especially notable that late-life vascular health appeared even more strongly associated with dementia risk than midlife health, which challenges the idea that 'it's too late' to make a difference after midlife."
So, what can you do to keep your vascular system healthy and reduce your risk of developing dementia? Here are some tips:
- Exercise regularly
- Eat a healthy diet rich in fruits, vegetables, and whole grains
- Maintain a healthy weight
- Limit your alcohol consumption
- Don't smoke
- Control your blood pressure and blood sugar levels
