Hi Junaej,
from what I can gather it sounds as if a mycotoxin is on the order of a mold or fungus, and if left untreated can cause other complications. I.e. black mold may cause neurological symptoms that might mimic symptoms of m.s.
Hopefully others will chime in to help answer your specific questions more fully as I simply don't have the answers for you.
If it's something that you have concerns about, I would encourage you to contact your health care provider with your questions.
Please keep us posted, it's an interesting question!
All the best, Janus
