Don't Wait for Alzheimer's — A Neurologist's 30-Year Plan to Protect Your Brain

The gist

1. Perlmutter says ultra-processed food raises Alzheimer's risk sharply, with 10 or more daily servings linked to a 270% higher risk.
2. Both aerobic and resistance training matter for brain health, as each one does a different job protecting brain function and metabolism.
3. A blood test for p-tau 217 can reveal brain immune dysfunction years before any cognitive symptoms show up.
4. Perlmutter says environmental toxins like paraquat and glyphosate damage mitochondria in brain immune cells, pushing them toward a destructive state.
