Brain HealthHeart Disease and Alzheimer's Share Deep Cellular Roots That Current Drugs Miss
Cardiovascular disease, Alzheimer's disease, and multiple sclerosis are more connected than most clinicians realize. They share a 'neurocardiac axis' driven by common cellular mechanisms: oxidative stress, cellular senescence, mitochondrial dysfunction, and gut microbiome disruption. The longevity protein SIRT1, the fat-transport protein APOE, and GLP-1 receptor agonists (like semaglutide) all sit at this intersection. Current treatments are largely symptomatic and fail to target these shared roots. Novel cell-death pathways—ferroptosis, pyroptosis, and autophagy—also play intertwined roles. The review argues that precision medicine targeting these overlapping mechanisms simultaneously could transform outcomes for patients suffering from both heart disease and cognitive decline, conditions that together affect hundreds of millions globally.
