Overview

Neurosyphilis is caused by Treponema pallidum, the bacteria that cause syphilis. It usually occurs about 10 - 20 years after a person is first infected with syphilis. Not everyone who has syphilis will develop this complication.

Pathophysiology

The forms of presentation of neurosyphilis can be grouped in two categories:[3]

  1. Early (asymptomatic, meningeal and meningovascular neurosyphilis)
  2. late (progressive general paralysis and tabes dorsalis).

Other less important forms are:

  • Gummas
  • Ocular forms
  • Syphilitic amyotrophy or hypoacusis

There are four different forms of neurosyphilis:

  • Asymptomatic (most common form)
  • General paresis
  • Meningovascular
  • Tabes dorsalis

Asymptomatic neurosyphilis occurs before symptomatic syphilis.
