[Interface neurology/psychiatry: a case report of neurosyphilis]. / Interfaz neurología/psiquiatría: un caso de neurosífilis.

Organic diseases can occur with different psychiatric symptoms. Neurosyphilis was considered to be a landmark in the history of organic mental syndromes. The complexity of its clinical picture decreases the boundaries between Neurology and Psychiatry and requires a multidisciplinary approach. We report a case of neurosyphilis that began with psychiatric symptoms in a twenty five years old male.
