Episode notes
Alzheimer's Mostly Preventable
- Around 97% of Alzheimer's disease cases are preventable through lifestyle changes.
- Alzheimer's is not a normal part of brain aging and can be stopped before it starts.
Dendrites Die, Not Neurons
- Neurons themselves don't die as we age, but the dendrites connecting neurons weaken and disappear.
- This loss of dendritic connections causes brain shrinkage and cognitive decline, not neuron death.
Toxic Proteins Block Connections
- Amyloid beta and tau proteins accumulate as toxic plaques and tangles that disrupt neuron connections.
- Amyloid exists outside neurons and clumps, blocking dendrites and causing brain networks to die off.
