title: [Neurosyphilis: a rare cause of dementia].
abstract: BACKGROUND
  Neurosyphilis had to be evoked in the face of an atypical dementia.
  
  
  METHODS
  We describe the case of a 65-year-old man who presented with neurosyphilis suspected to precede behavioral and cognitive problems in the context of risky sexual behavior and was confirmed by serologic tests in the cerebrospinal fluid.
  
  
  CONCLUSIONS
  This case proves the necessity to investigate the possibility of neurosyphilis in subjects with dementia syndrome which does not correspond to classic etiologies.
