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
- It is understood that neurosyphilis is caused by Brain and spinal cord invasion of treponema pallidum infection.[1]
- Neurosyphilis is a manifestation of invasion of treponema pallidum spirochetes to the brain and dorsal column of spinal cord in tertiary syphilis.[2]
- Neurosyphilis usually occurs in patients who have untreated syphilis for a long time, usually about 10 to 20 years after first infection by treponema pallidum
- Only 25%–40% of persons who are not treated with penicillin will develop neurosyphilis.
The forms of presentation of neurosyphilis can be grouped in two categories:
- Early (asymptomatic, meningeal and meningovascular neurosyphilis)
- 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.
