This work explores the vascular hypothesis as a mechanism underlying both Alzheimer's disease and vascular dementia, with particular attention to how cardiovascular risk factors contribute to dementia development. The research examines prevalence patterns and etiological factors specific to African populations, addressing potential disparities in dementia pathophysiology and risk profiles.
This meta-analysis of 16 cohort studies found that high body weight fluctuation is associated with increased risk of all-cause dementia, Alzheimer's disease, and vascular dementia, with hazard ratios ranging from 1.33 to 1.40 compared to stable weight. No significant association was found between weight variability and general cognitive decline, and evidence certainty was assessed using rigorous GRADE methodology.
