The Optispan Podcast with Matt Kaeberlein Why 400+ Alzheimer's Drugs Failed (Here's What Works)

Oct 5, 2025 Dr. Cory, a systems biologist at the Institute for Systems Biology and co-founder of Fulcrum, explores innovative perspectives on Alzheimer's. He argues that it's not just about amyloid plaques, but rather a flawed debris management system in the brain, particularly concerning cholesterol. Discussing the roles of genes like ApoE4 and the impact of lifestyle factors, he sheds light on why current drugs often fail. Dr. Cory also highlights practical prevention tips, emphasizing sleep, diet, and personalized lifestyle choices to combat Alzheimer's.

Episode notes
Test Models Against Population Patterns
- Validate models by reproducing population-level biomarkers like APOE-stratified incidence curves.
- Digital twins work best when they reconcile diverse orthogonal datasets, not perfect precision of one measure.
Metabolic Failure Drives Tau Pathology
- Energy deficits link directly to tau phosphorylation via ATP and calcium dysregulation.
- Metabolic failure in astrocyte–neuron support can trigger tau-related pathology.
Why Mouse Models Often Mislead
- Standard transgenic mouse models miss decades-long debris accumulation seen in aging humans.
- Young engineered mice lack the aging context, which likely causes preclinical-to-clinic failures.
