In a 2026‑09‑15 episode of The Empowering Neurologist, Dr. David Perlmutter interviews Dr. M. Marc Abreu, a physician‑biomedical engineer and founder of BTT Medical Institute, about his novel brain‑guided temperature therapy (CBIT2) that purportedly reverses amyotrophic lateral sclerosis (ALS). Dr. Abreu outlines his interdisciplinary training (Brazilian medical school, ophthalmology, physics, Harvard, Department of Defense, laser research, Yale) and the historical precedent of cyclical fever therapy (malaria‑induced fever) used to treat neurosyphilis (dementia paralytica). He explains the thermodynamic rationale: the brain’s language is temperature variation, and controlled hyperthermia can activate intrinsic repair mechanisms. The FDA‑cleared CBIT2 system uses real‑time brain temperature monitoring and AI‑driven cyclical heating. Clinical evidence is presented via a published case report from the Mayo Clinic (EMG‑confirmed ALS, post‑treatment EMG shows no dying motor neurons, patient no longer meets diagnostic criteria) and a detailed patient testimonial from “Kent,” a swimmer diagnosed with ALS who underwent 12 hyperthermia sessions, reporting immediate symptom relief (swallowing, walking) and stable or improved functional measures, though pulmonary function tests remain unchanged. The conversation addresses natural skepticism from the neurology community, the need for rigorous clinical trials, ongoing FDA‑approved studies, and the broader potential of temperature‑based therapy for other neurodegenerative diseases. Kent’s story illustrates rapid word‑of‑mouth dissemination and patient‑driven advocacy. The episode also includes brief promotional segments unrelated to the core claim. The overall narrative positions CBIT2 as a potentially paradigm‑shifting, physics‑based approach to neurodegeneration, while acknowledging the current lack of widespread clinical acceptance.
