Elena Castellanos Cuts Alzheimer’s Biomarkers by 32% After Discovering 10- to 15-Fold Genetic Risk
1 articles · Updated · TODAY · Jul 19
Summary
Nearly one year after learning she carries two APOE e4 copies, Elena Castellanos lowered a key brain inflammation marker by 32%, with amyloid improving 20% and an early tau marker 29%.
The 57-year-old Miami school administrator pursued preventive neurology after a 2024 genetic test showed the rare genotype, found in just 2% to 3% of people and tied to about a 10- to 15-fold higher Alzheimer’s risk.
Her changes centered on modifiable dementia risks: a Mediterranean-style diet, cholesterol treatment, resistance and cardio workouts, stricter sleep habits to manage sleep apnea, no alcohol, and regular medical, dental, eye and hearing care.
Dr. Kellyann Niotis said the biomarker shifts do not guarantee Castellanos will avoid Alzheimer’s, but likely signal lower neurodegenerative risk, much as improved cholesterol lowers heart-attack risk.
The case also highlights the limits of early prevention: blood tests tracking tau and amyloid can cost roughly $900 to $2,000 each, with insurance coverage still uneven.

From Genetic Risk to Measurable Progress: Elena Castellanos’ 2025 Alzheimer’s Biomarker Reductions Through Lifestyle Change
Overview
In 2024, Elena Castellanos, who had a high-risk profile for Alzheimer’s disease due to carrying two copies of the APOE4 gene, began a proactive intervention strategy. Research confirmed that this genetic profile greatly increases the chance of developing Alzheimer’s. However, growing evidence shows that healthy lifestyles can benefit older adults regardless of genetic risk. Structured lifestyle interventions, like those studied in the U.S. POINTER trial, provide substantial health benefits, including improved cognition and a lower risk of cognitive decline. By combining modifiable behaviors, Elena aimed to effectively reduce her Alzheimer’s disease risk.
