1A62.00/A52.2 Asymptomatic neurosyphilis



Asymptomatic neurosyphilis is caused by the bacteria Treponema pallidum, which is usually acquired through sexual contact. It is the most serious form of syphilis, as it can cause damage to the nervous system, including the brain and spinal cord.


Asymptomatic neurosyphilis is often diagnosed by a blood test that checks for the presence of antibodies to Treponema pallidum. In some cases, a lumbar puncture may be done to look for signs of inflammation or infection in the cerebrospinal fluid.

Differential diagnosis

Asymptomatic neurosyphilis can be confused with other neurological conditions, such as multiple sclerosis or Alzheimer’s disease. It is important to rule out other possible causes before making a diagnosis of asymptomatic neurosyphilis.


Treatment for asymptomatic neurosyphilis typically involves a course of antibiotics, such as penicillin. This is usually given intravenously for a minimum of 10 days. In some cases, longer courses of antibiotics may be needed to treat the infection.


The prognosis for asymptomatic neurosyphilis is usually good, provided that the condition is diagnosed and treated promptly. With appropriate treatment, most people with asymptomatic neurosyphilis can go on to live healthy, normal lives.
