5 min read

Dr. Richard Horowitz, a board-certified internist who has treated over 13,000 patients in 41 years, has spent his career arguing that chronic illness is not a mystery. He developed the MSIDS model—16 hidden factors that include infections, toxins, microbiome disruptions, and vitamin deficiencies—to explain why patients with conditions like Lyme disease, autoimmune disorders, and even Alzheimer’s fail to get better with standard treatment. His most recent study, published in the Journal of Alzheimer's Disease Reports, showed that a nine-week oral antibiotic protocol reversed PTau 217, the most sensitive and specific Alzheimer’s biomarker, for the first time in the medical literature. The conversation with Gary Brecka is a deep dive into how these same 16 factors drive everything from brain fog to dementia, and what a practical diagnostic and treatment roadmap looks like.

Mold toxins show up in 90% of Dr. Richard Horowitz's chronically ill patients, and Lyme shows up in more. After 41 years and 13,000 cases, he just published the first documented reversal of an Alzheimer's blood marker using nine weeks of oral antibiotics.
