What Causes Brain Fog? The Blood-Brain Barrier, Brain Inflammation & Cognitive Decline

If you’ve been struggling with brain fog, fatigue, poor concentration, or memory issues and you’ve been told everything looks “normal,” this episode will help you understand what may actually be going on beneath the surface.We explore the emerging science behind the blood-brain barrier, a protective system that shields your brain from inflammation, toxins, and immune activity in the rest of the body. When this barrier is functioning well, your brain operates with clarity and stability. But when it becomes compromised, it may allow inflammatory signals, immune activity, and metabolic stress to affect cognitive function, potentially contributing to brain fog, fatigue, mood changes, and long-term cognitive decline.02:00 — Why the brain is different from the rest of the body06:10 — What is the blood-brain barrier?
