Episode notes
Decades Of Clinical Observations
- Berner describes lithium as a metabolic drug with broad effects beyond psychiatry, based on decades of observation.
- He mentions longer telomeres, less MRI atrophy, and lower Alzheimer's rates in lithium-treated people.
Cheap Drug, Big Implications
- A single inexpensive drug like lithium can regain legitimacy as an Alzheimer's candidate after rigorous research.
- Jon Berner highlights the Nature study as a breakthrough because lithium costs ~$40/year and was previously ignored.
Locality Over Global Levels
- Local (paracrine) lithium depletion in brain regions matters more than global blood levels for Alzheimer's mechanisms.
- Berner frames this as a quantum/locality problem versus classical endocrine signaling.
