Neurosyphilis Update: Atypical is the New Typical

Abstract

Syphilis has reemerged as an important cause of neurological disease, affecting any part of the neuraxis at any stage of infection. What was once a dwindling diagnosis is now redoubling, particularly in the HIV-positive and in men who have sex with men populations. In the era of antibiotics and HIV coinfection, neurosyphilis presentations are protean, making diagnosis notoriously challenging. Advanced disease may be irreversible, and so early detection and treatment are ideal. Herein, we review recent advances in understanding neurosyphilis.
