Episode Title: Recap: Tips to help prevent Alzheimer’s
Date: December 16, 2025

This episode dives into actionable, science-backed strategies to prevent Alzheimer's and boost brain health, featuring renowned neurologists Drs. Ayesha and Dean Sherzai. They discuss how Alzheimer’s risk accumulates over decades and break down their practical "NEUROPLAN" for listeners of all ages to support cognitive longevity.

Key Discussion Points & Insights

1. Why Alzheimer’s is Rising & What It Means for You

• Advances in health have extended our lifespan, but not always our brainspan ([00:01]).
• Lifestyle factors over decades influence brain health—choices you make today matter for tomorrow ([00:01–02:22]).

Quote:
"Rates of Alzheimer's are rising and the big question is why? Emerging science suggests that our brain health in later life is shaped decades earlier through everyday choices around food, lifestyle and stress."
— Host, Jonathan Wolf ([00:01])

2. The NEUROPLAN Framework: Five Pillars for Brain Health

Drs. Sherzai introduced their memorable NEUROPLAN, summarizing preventive lifestyle domains:

• N: Nutrition
• E: Exercise
• U: Unwind (Stress Management)
• R: Restorative Sleep
• O: Optimize Cognitive Activities
  ([00:53–06:41])

Quote:
"We've created this acronym called neuro... N stands for nutrition, E, exercise, U, unwind or stress management, R is restorative sleep, and O is optimizing cognitive activities or building cognitive resilience."
— Dr. Ayesha Sherzai ([00:53])

3. The Brain: Built for Health, But Vulnerable

• The brain is just 2% of body mass, but uses 25% of energy and 50% of oxygen ([03:08–03:22]).
• It's the body's most vascular organ—anything that affects your heart, blood vessels, or metabolism also impacts your brain ([03:21–05:00]).

Quote:
"This little three pound organ, which is 2% of your body's weight, consumes 25% of your body's energy."
— Dr. Dean Sherzai ([03:08])

4. Small Changes, Big Differences: Empowering Prevention

• Incremental improvements—even minor tweaks to nutrition, exercise, sleep, or stress—add up ([05:00–06:16]).
• There’s no “all or nothing”: Every positive step counts ([05:00–06:16], [09:09–09:54]).

Quote:
"It's not all or none. Every positive move you make incrementally helps the brain... This is an empowering message."
— Dr. Dean Sherzai ([05:00])

5. Nutrition: The Evidence and Practical Strategies

• Diets high in plant-based foods—leafy greens, whole grains, nuts, seeds, polyunsaturated fats—reduce brain aging ([06:43–09:54]).
• The MIND Diet (hybrid of Mediterranean and DASH) lowers Alzheimer’s risk by up to 53% with high adherence, and even moderate adherence slashes risk by 37% ([09:00–09:54]).
• Positive dietary changes don’t require perfection. Swapping a donut for fruit or adding more leafy greens makes a measureable impact ([09:54–10:20]).

Quote:
"When they adhere to the MIND Diet, they reduce their risk of developing Alzheimer's disease by 53%. And even moderate adherence reduced the risk by 37%."
— Dr. Ayesha Sherzai ([09:33])

6. Personalized Nutrition vs. “Brain Diet”

• The best overall diet for your heart or metabolic health is also effective for your brain—no need for a separate, brain-specific diet ([11:00–11:15]).
• Three nutrients to monitor closely for brain health:
  • Vitamin B12: Keep levels at normal/high range.
  • Vitamin D
  • Omega-3s: DHA is particularly critical.
    • Fish (salmon, mackerel, sardines, etc.), chia, flaxseed, or supplements ([11:15–13:15]).
    • Be mindful of Omega-3/Omega-6 balance (favor Omega-3, limit processed foods high in Omega-6).

Quote:
"The three elements that are important for brain: B12, make sure that your B12 levels are normal or on the higher side, vitamin D and Omega 3... DHA for the brain in particular makes up more than 50% of brain's volume."
— Dr. Dean Sherzai ([11:15])

Memorable Moments & Quotes

• On the Brain's Power Demand:
  "It consumes 25% of your body's energy... has more arteries and veins than any other organ in the body."
  — Dr. Dean Sherzai ([03:08–03:22])

• On Empowerment Through Small Change:
  "Every small incremental change towards that positive outcome... actually made a huge difference. And I think that's pretty empowering for people to know that you don't have to jump into it wholeheartedly."
  — Dr. Ayesha Sherzai ([09:54–10:20])

• On Shared Lifestyle Benefits:
  "It's the same diet, whether it's for heart, for everything else... to the best of our knowledge today."
  — Dr. Dean Sherzai ([11:15])
