Is Alzheimer's an Infection? How the Brain's Immune System Might Hold the Answer

When we think about the immune system, most of us picture white blood cells fighting off a cold or healing a cut. But here’s something crucial to keep in mind: your brain has its own immune system that works entirely different than the rest of your body.

As the CAD Foundation funds research into the microbial / infectious hypothesis of Alzheimer’s, this idea of the brain having its own immune system is very important. Especially in instances where something foreign ( environmental toxin or even a bacterial, viral, or fungal cell ) gets past the blood brain barrier where it’s not supposed to be.
