Last edited: 4/10/2026

Overview

Neurosyphilis is a serious complication of untreated syphilis that can affect the central nervous system 1. Secondary neurosyphilis is a stage of the infection that can manifest with a variety of neurological symptoms, including headaches 1.

Diagnosis

  • Headache can be a presenting symptom of secondary neurosyphilis 1.
  • Diagnosis requires a high index of suspicion in patients with compatible symptoms and a history of syphilis 1.
    • Diagnostic workup typically includes cerebrospinal fluid (CSF) analysis for Treponema pallidum* antibodies, cell count, and protein levels 1.

    Management

  • Treatment for neurosyphilis generally involves high-dose penicillin 1.
  • Specific treatment regimens and duration may vary based on clinical presentation and patient factors 1.

    • Key Recommendations

  • Recognize headache as a potential symptom of secondary neurosyphilis and consider it in the differential diagnosis of secondary headaches 1. (Evidence: Expert opinion)
  • Evaluate patients with suspected neurosyphilis using CSF analysis 1. (Evidence: Expert opinion)
  • Treat neurosyphilis with penicillin 1. (Evidence: Expert opinion)
