[The current role of neurosyphilis in the differential diagnosis of neuropsychiatric diseases].

Over a period of eight years, 16 patients from a non-selected number of patients in a neuropsychiatric special hospital were diagnosed to suffer from neurolues not known so far. Apart from the classical clinical pictures (PP and T. d.) meningovascular courses of disease with apoplectiform onset have been dominant since 1980. The patients concerned were nearly exclusively younger male adolescents. The decline in the classical development of neurolues in favour of meningovascular and atypical clinical pictures makes clinical diagnosis more difficult and requires routine application of standardized specific and serological tests in clinical practice.
