Neurosyphilis


Neurosyphilis

Neurosyphilis is an infection of the brain or spinal cord caused by the bacterium Treponema pallidum. It usually occurs in people who have had untreated syphilis for many years, usually about 10 - 20 years after first infection.[1]

Diagnosis

In addition to evaluation of any symptoms and signs, various blood tests can be done:[1]

Also, it is important to test the cerebrospinal fluid for signs of syphilis.[1]

Additional tests to look for problems with the nervous system may include:[1]

  • Cerebral angiogram
  • Head CT scan
  • Lumbar puncture ("spinal tap") to acquire a sample for cerebrospinal fluid analysis
  • MRI scan of the brain, brainstem, or spinal cord

Treatment

Penicillin is used to treat neurosyphilis. Two examples of penicillin therapies include:[1]

Follow-up blood tests are generally performed at 3, 6, 12, 24, and 36 months to make sure the infection is gone.[1] Lumbar punctures for CSF fluid analysis are generally performed every 6 months.
