Episode notes
Small Changes Trigger Wide Brain Health Cascades
- Lifestyle changes cascade because brain health systems are interconnected.
- Wood: improved sleep increases social engagement and cognitive activity, blood pressure and glucose, creating broad downstream benefits.
AI As A Cognitive Orthotic Example
- Tommy Wood calls AI a potential 'cognitive orthotic' that can extend thinking if used interactively.
- He warns passive offloading could atrophy skills; the tool must prompt engagement not replace it.
Genes Are Risk Modifiers Not Fate
- Genetics modify risk but don't determine destiny; environment and lifestyle strongly interact with genes like APOE4.
- Wood cites Sicilian studies where ApoE4 raised risk in America but not in Sicily, showing context dependence.
