Great question! It is my understanding that candida secretes a mucous as a waste product in which it also inhabits. Once the candida works it's way into the bloodstream it can eventually end up in the cerebral area. Once there, the mucous begins to inhibit neural transmitters by encompassing the nerve endings. Conditions of the nervous system in which candida is linked include Parkinson's, Alzheimer's, Lupus, MS, and ADHD to name a few. And these do not include birth defects that could result from an infected pregnant mother on a newborn baby. I'm not sure if it can physically involve the spinal cord, but candida has shown that it can penetrate to all areas of the body so I wouldn't be a bit surprised.
