Alzheimer’s Isn’t “Just Aging”: Human Brain Data Shows a Distinct Mitochondrial Collapse — Especially in the Hippocampus
Most conversations about Alzheimer’s and mitochondria stay in broad strokes. This Deep Dive episode doesn’t. Dr. Mike Belkowski breaks down a study that examined postmortem human brain tissue to answer a precise question: do mitochondrial electron transport chain proteins shift in Alzheimer’s the same way they shift in normal aging — or is Alzheimer’s a different mitochondrial pattern entirely?
Using three groups (young controls 35–45, aged controls >85 without Alzheimer’s pathology, and sporadic Alzheimer’s cases 85–89), the researchers measured neuron-level immunohistochemical intensity (a…
