WHAT IT’S REALLY ABOUT
Lauren Rogen and Dr. Isaacson on Preventing Alzheimer's Through Personalized Strategies
- Lauren Miller Rogen describes watching her grandparents, her mother (symptomatic around age 52) and later her uncle develop Alzheimer's, and how that drove her toward advocacy and prevention.
- Richard Isaacson explains that Alzheimer's is heterogeneous and polygenic, with ApoE4 the most common genetic risk factor and other genes such as TOMM40 and a TNF-alpha-related gene modifying risk.
- Isaacson argues that sex differences in risk are driven largely by the perimenopause transition, surgical menopause, and visceral fat in women, rather than longevity alone.
- The clinic's approach combines roughly 21 individualized interventions (exercise, omega-3s, vitamin D, curcumin, B vitamins and more) with six-monthly tracking of body composition, blood biomarkers, and cognition.
- Lauren reports improved cognitive scores and less fear thanks to feeling in control, and she describes how her nonprofit HFC supports caregivers and educates young people about brain health.
IDEAS WORTH REMEMBERING
5 ideasAlzheimer's begins in the brain decades before symptoms.
Isaacson describes a preclinical stage with no symptoms, citing a figure of 46 million Americans with Alzheimer's in the brain, which makes it the key window for prevention.
Alzheimer's is heterogeneous rather than a single uniform disease.
Isaacson says symptoms depend on where pathology spreads, producing forms such as dysexecutive syndrome, PART, or visual-perception problems, and Peter Attia likens this to cancer being many diseases.
ApoE4 raises risk but is not destiny, and not all E4s are equal.
Both Lauren's mother and uncle were 4/4 yet their onset differed by roughly 15 years, which Isaacson attributes to polygenic risk, TOMM40, a TNF-alpha-related gene, lifestyle, and hormones.
Women face distinct risk, especially around menopause.
Isaacson points to the perimenopause transition as a window of opportunity, notes that Lauren's mother had a hysterectomy around age 46, and says visceral fat and a larger waist circumference matter especially in women.
Exercise is the top lever, particularly for ApoE4 carriers.
Isaacson says optimized physical activity is the number one recommendation and that high-intensity interval training may be one of the few things moving cognitive function in E4 carriers.
WORDS WORTH SAVING
5 quotesScience gives us tools. I don't wanna live in the dark and not use the few tools that I've been given at this point. That seems way worse to me.
— Lauren Miller Rogen
Alzheimer's disease starts in the brain decades before the first symptom of memory loss begins, and I didn't learn that in medical school. I hate to say it, but most doctors don't know that still.
— Dr. Richard Isaacson
But again, genes are not our destiny. We can absolutely win the tug-of-war against our genes.
— Dr. Richard Isaacson
Emotionally, yes, so much of the fear has dissipated because I have control in a way that I didn't before. I see my blood work, you know? I see numbers going from red to green, and that gives me a hope.
— Lauren Miller Rogen
Alzheimer's is so devastating and it is so sad and people don't wanna hear about it, so we'll tell them some jokes and trick them into laughing and then all of a sudden we hit them with the facts and tell them how important it is, and we rope them in that way.
