Neurosyphilis presenting as rapidly progressive psychosis & dementia - A forgotten entity.

Syphilis is described often as great imitator due to its varied clinical manifestations. Neurosyphilis a tertiary form of syphilis can present in the form of meningitis, meningovascular syphilis with strokes and in advanced stage as general paralysis of insane. Paretic stage of neurosyphilis presents with progressive psychiatric and cognitive impairment. The cognitive impairment can range from subtle to advanced dementia. This is the rationale for routing screening for syphilis in evaluation of dementia. There are few reports on neurosyphilis presenting as rapidly progressive dementia. We report a case of neurosyphilis presented with rapidly progressive dementia along with psychotic symptoms.
