Using Precision Medicine to Reverse Alzheimer's Disease with Dr. Heather Sandison | Rational Wellness Podcast 464

Dr. Ben Weitz interviews Dr. Heather Sandison about a precision, multimodal approach to Alzheimer’s and cognitive decline that challenges the amyloid-only model. Sandison cites a 2026 Cochrane review finding anti-amyloid antibody therapies remove plaque but don’t meaningfully improve cognition and carry risks like brain bleeding and swelling, arguing cognitive decline is driven by multiple modifiable factors. She reviews lifestyle-intervention research (Bredesen/Toups 2022, her 2023 study, Ornish 2024, and the Alzheimer’s Association POINTER trial) showing cognitive improvements, discusses key drivers such as toxins (mycotoxins, metals, chemicals), infections, metabolic flexibility/ketosis, sleep, stress, and social connection, and outlines evaluation tools including MoCA, CNS Vital Signs, MRI volumetrics with arterial spin labeling, and blood biomarkers like p-tau217, Aβ 42/40, and NfL, plus interpreting nutrients via homocysteine.
