I’m an otherwise healthy male, married 20+ years. I had a minimally reactive FTA-Abs following several months of fatigue, abdominal pain, nausea and the onset of neuropathy and autonomic issues. Repeat testing has been negative however the neurological issues and autonomic symptoms have progressed with elevated CSF protein for over a year now (low cell counts, neg CSF VDRL). What other conditions can cause the FTA to be weekly positive, RPR negative and cause elevated CSF protein with associated neurological issues?
