Our study emphasizes the importance of CMDs (i.e., insufficient physical activity, obesity, diabetes, prediabetes, and stroke), inflammation, insulin‐related processes, cerebrovascular disease (i.e., greater SVD burden, particularly WMHs, lacunes, large infarcts, and white‐matter microstructural abnormalities) for deviations from “expected” CA, that is, BAG. Here, INS is linked to obesity disorder.
