Dr. Diane Mueller explains the concept of blood-brain barrier disease ("leaky brain") and why it matters: when the barrier weakens, toxins and other substances can enter the brain more easily, triggering inflammation and possible neuronal death. She links leaky barrier states to exposures such as mycotoxins and heavy metals and emphasizes managing factors like cholesterol to reduce risk.
So it's really important to understand that we can develop blood brain barrier disease. This is essentially when the brain becomes leaky. And when the brain becomes leaky, there's less of a barrier separating the brain from the rest of the body, meaning things can get into the brain a lot easier. This is basically the brain essentially trying to attack these toxins and remove them, but subsequently creating a large enough chain reaction that we get an inflammatory stress in the brain and this can actually cause our nerve cells in the brain to die. So it's really important that we work with blood brain barrier disease. We absolutely don't want those toxins in our body to begin with. But you also need to talk and think about how does the blood brain barrier get leaked. So if you have mycotoxin illness or you have metals or you suspect these things, you want to make sure you're really also managing your cholesterol to prevent these things getting into the brain.
