title: Atypical behavioral and psychiatric symptoms: Neurosyphilis should always be considered.
abstract: Syphilis still remains a major health concern worldwide because of the possibility of serious medical and psychological consequences, long-term disability, and death. Neurosyphilis (NS) may occur at any stage of infection. Its clinical presentation has been changing over recent years including- psychiatric and neurocognitive symptoms. Several recent studies have described cases with these symptoms as the principal signs of NS. We present the case of neurosyphilis with a psychiatric presentation characterized by mood disturbance and auditory and visual hallucinations.
