In today's episode, Haylie Pomroy sits down with Dr. Theoharis Theoharides, one of the world's foremost experts on mast cell activation syndrome and neuroinflammation, to break down what brain fog actually is, what is driving it at the cellular level, and what can be done about it. Dr. Theoharides explains how the brain's own immune cells, known as microglia, can become destructive when triggered by viral particles, spike protein, mold, or other inflammatory agents. He details how COVID spike protein can enter the brain through the blood-brain barrier and the olfactory nerve, persist for up to two years, and activate a cascade of neuroinflammation that disrupts memory, cognition, and mood. He also shares the latest developments in diagnostic tools, including SPECT imaging and an emerging biosignature panel designed to finally give patients measurable, objective evidence of what is happening in their brains. He walks through the most evidence-backed interventions his team is using to protect and restore brain cell function, including folinic acid, luteolin-based flavonoids, and hydroxytyrosol from olive leaves, and why supplement quality matters more than most people realize.
