We observed 24 patients with symptomatic neurosyphilis. Of these 24 patients, nine had clinical manifestations of general paresis, seven tabetic neurosyphilis, five meningovascular neurosyphilis, one taboparetic, one tabomeningovascular, and one spinal neurosyphilis. Confusion, disorientation, lancinating pain, impaired memory, and bizarre behavior were the most prevalent symptoms. Sensitivity of the CSF FTA-ABS test was higher (96%) than that of the CSF VDRL test (79%). CSF cell count and total protein determination may be inadequate for assessing activity of neurosyphilis.
