title: [Neurosyphilis: forms of presentation and clinical management].
abstract: OBJECTIVE
  Neurosyphilis results from the infection of the central nervous system by Treponema pallidum. It causes diverse clinical pictures which are occasionally similar to other, better known neurological diseases. In this paper our aim is to offer a global clinical vision of this entity by reviewing the different forms it can take and its diagnostic and therapeutic management.
  
  
  METHODS
  The forms of presentation of neurosyphilis can be grouped in two categories: early (asymptomatic, meningeal and meningovascular neurosyphilis) and late (progressive general paralysis and tabes dorsalis). Other less important forms, such as gummas, ocular forms, syphilitic amyotrophy or hypoacusis, have also been described. Diagnosis is complex and is based on the study of the cerebrospinal fluid. Given the difficulty involved in performing an accurate diagnosis, different criteria have been developed in which T. pallidum serology plays a key role. The most effective treatment is penicillin, although on occasions it may have no effect and we therefore recommend clinical and fluid analysis follow ups. Lastly, we describe the changes in incidence and clinical presentation, and the complications that may arise in diagnosis when HIV carrying patients also suffer from this disease.
  
  
  CONCLUSIONS
  Neurosyphilis is a disease that still occurs nowadays and, due to its clinical polymorphism, must be borne in mind as a differential diagnosis in a number of neurological and psychiatric illnesses. This, together with the fact the serological tests are difficult to interpret and its irregular response to the usual treatment, makes it difficult to manage and means that the neurologist must have a thorough knowledge of the disorder.
