Horowitz links chronic inflammation to cognitive decline
302. The Antibiotics That Reversed Alzheimer's Blood Marker - Dr. Richard Horowitz
The conversation challenges single-cause explanations for dementia by examining infections, toxins, immune dysfunction, and metabolic factors as potentially connected contributors.
- 1Horowitz applies his 16-factor MSIDS model to cognitive decline, combining infections, toxins, gut dysfunction, deficiencies, and mitochondrial problems.
- 2He reports Alzheimer’s-related blood-marker changes after a nine-week oral antibiotic protocol, while emphasizing personalized testing and treatment.
- 3The discussion connects Lyme, Bartonella, mold, long COVID, inflammation, and environmental exposure to neurological and autoimmune disease patterns.

Horowitz reports that a nine-week oral antibiotic protocol was followed by changes in an Alzheimer’s-related blood biomarker.
The brief
Dr. Richard Horowitz describes chronic illness as a systems problem, linking Lyme and co-infections with mold, metals, gut dysfunction, mitochondrial stress, and inflammation.
The episode’s sharpest claim is a reported reversal in an Alzheimer’s-related blood biomarker after nine weeks of oral antibiotics, presented as evidence for investigating persistent infection.
Horowitz explains his 16-factor MSIDS model, which expands a chronic-illness workup beyond infection to include toxins, microbiome disruption, deficiencies, sleep, stress, and mitochondrial dysfunction.
The conversation moves from Lyme and Bartonella to long COVID and autoimmunity, arguing that overlapping infections and inflammatory pathways can produce neurological symptoms.
For cognitive decline, Horowitz recommends staged testing for infections, mold, metals, inflammatory markers, adrenal function, and other contributors before symptoms become severe.
