Neurosyphilis-Induced Psychosis: A Unique Presentation of Syphilis With a Primary Psychiatric Manifestation.

Syphilis is a predominantly sexually transmitted infection caused by the spirochete Treponema pallidum. The infection presents with four different stages and although rare, can lead to behavioral symptoms if not treated in its earliest form. It can cause psychosis, mania, depression, anxiety, and personality changes. Screening and early treatment of syphilis are essential in preventing neurosyphilis and its neuropsychiatric symptoms. Neurosyphilis is rarely the initial presentation of syphilis. This is a case report of a 30-year-old female with neurosyphilis who presented with psychosis as the primary presentation.
