I have had sleep apnea problems since I was 20-21 for over 4-5 years . My sleep test told there wasn't much apnea but only obstructive and no central . I had an exposure 13 years back and i tested for syphillis TPHA negative twice and vdrl once negative. I'm seeing a neurologist who doesn't think it's neurosyphillis. Are these tests enough ? Without serologic evidence , do doctors go for CSF test ? Or is syphillis ruled out ? I also tested negative for
HIV rapid , tridot pcr, western blot , HBV , HCV all negative. My brain MRI was normal .
