Evidence Map

What The Sources Report

• The most common one includes vascular risk factors, which are central to the pathogenesis of VaD but also contribute significantly to AD and other dementias. [González-Cidad Aitor (2026); evidence level 3]
• These modifiable risk factors include arterial hypertension -the major risk factor at the population level-as well as dyslipidemia and high body mass index (BMI), all of which can trigger inflammation and stenosis of cerebral blood vessels, leading to reduced blood flow and neural tissue damage. [González-Cidad Aitor (2026); evidence level 3]
• More recently, the focus has shifted to how eating habits can influence and reduce vascular risk. [Pacinella Gaetano (2026); evidence level 4]
• The purpose of this article is to compile and present recent findings on how the MedDiet can lower cerebrovascular risk, while highlighting the pressing need to incorporate nutritional strategies into both medical practice and public health initiatives aimed at preventing vascular diseases. [Pacinella Gaetano (2026); evidence level 4]

How To Read This Evidence

Level 3 usually reflects observational or narrative-review evidence. Level 4 is weaker or early-stage evidence. The level is a sorting aid, not a final quality grade.
