[Organic origin of maniform psychosis. A case example of progressive paralysis].

A 36-year-old patient with a highly developed manic-type psychosis is presented. The precise, thorough psychopathological examination indicated organic illness. The diagnosis of neurosyphilis was established when specific CNS-derived immunoglobulin was detected. The existence of increased general inflammatory parameters in the CSF indicated that the condition was active. Treatment with penicillin resulted in clear improvement of laboratory findings, but clinical recovery was only partial.
