Alzheimer’s is usually framed as plaques and tangles—but this Deep Dive goes upstream: mitochondrial failure and impaired mitophagy. Dr. Mike Belkowski breaks down mitophagy as the brain’s selective mitochondrial cleanup system—and why neurons are uniquely vulnerable when damaged mitochondria can’t be transported, tagged, and fully degraded.

You’ll learn how mitophagy appears impaired across multiple steps in Alzheimer’s (initiation, recruitment, transport, lysosomal fusion, and degradation), how hallmark factors like tau, amyloid-beta, APP fragments (APP-CTFs), and APOE4 can jam the…
