 | | Late neurosyphilis (brain or spinal cord damage) is one of the most severe signs of this stage. |
 | | There are two laboratory methods for making the diagnosis: by identifying the bacteria in a sample taken from a lesion and placed on a microscope slide and by performing a blood test for syphilis. |
 | | If you have neurosyphilis, you may need to receive daily doses of penicillin intravenously (in the vein) and may need to be treated in the hospital. |
