The discussion highlights emerging research linking Borrelia burgdorferi (Lyme disease) to amyloid production and Alzheimer’s biomarkers, along with the clinical implications of Dr. Horowitz’s MSIDS model. Topics include biofilm persistence, co-infections, treatment resistance, and multi-targeted strategies for addressing complex, chronic conditions such as Lyme disease, ME/CFS, fibromyalgia, and long COVID.
