Occult infection- a hidden infection first recognized by secondary manifestations such as fever of unknown origin, or increased white blood cell count. Often caused by a bacterial infection in an obscure site.
I obsess about obsession because it seems like the best use of the pathology.
Not that I really have any choice...
I believe that the majority of mental illness is secondary symptoms of common chronic infections. I was a medical librarian, and now I just pretty much constantly research sleep disorders, depression, mania and dementia. This is where I collect my accumulating hypotheses and try to document the atrocities occurring daily in the Infection Industrial Complex.
My goal is not to convince you that my ideas are right, but to show you there is more than one way to interpret scientific data.
Update: After fifteen years of this, I finally think I am right.
