Top Psychiatrist Claims Medical Schools Still Teach False Blood-Brain Barrier Theory

What was said

"When I was at medical school, which was in the 1980s, one of the things we were taught as a matter of fact is that the brain is somehow protected from the immune system. The jargon for it was the brain is immune privileged. It sort of sits outside the immune system. And that was supposed to be because it was protected by this thing called the blood-brain barrier. To be honest, it doesn't really exist."

Ed Bullmore reveals that medical schools continue teaching that the blood-brain barrier completely protects the brain from immune system activity, a concept he says is fundamentally false. He explains that inflammatory hormones and white blood cells can cross this barrier, meaning bodily inflammation directly affects brain function. This outdated teaching has led generations of doctors to miss the physical causes of mental health symptoms.
