==Differential Diagnosis==
Neurosyphilis must be differentiated from other diseases that cause abnormal [[gait]], [[Blindness]], [[confusion]] and [[depression]], such as [[multiple sclerosis]], [[Brain tumour]]<nowiki/>s, [[Wernicke's encephalopathy|Wernicke’s encephalopathy]], [[CNS abscess]], [[electrolyte disturbance]], [[Subdural empyema]], [[Subarachnoid hemorrhage|subarachnoid  hemorrhage]], [[Stroke|brain stroke]], [[Conversion disorder]] and [[Drug toxicity]].


==Differentiating X from other Diseases==
* Neuroyphilis has an extensive differential diagnosis.
*Neurosyphilis must be differentiated from other diseases that cause abnormal [[gait]], [[Blindness]], [[confusion]] and [[depression]], such as [[multiple sclerosis]], [[Brain tumour]]<nowiki/>s, [[Wernicke's encephalopathy|Wernicke’s encephalopathy]], [[CNS abscess]], [[electrolyte disturbance]], [[Subdural empyema]], [[Subarachnoid hemorrhage|subarachnoid  hemorrhage]], [[Stroke|brain stroke]], [[Conversion disorder]] and [[Drug toxicity]].<nowiki/><nowiki/><ref name="pmid1278192" /><ref name="pmid3883130" /><ref name="pmid22482824" /><ref name="pmid24365430" /><ref name="pmid22421697" /><ref name="pmid21807345" /><ref name="pmid21371327" /><ref name="pmid14585453" /><ref name="pmid1198628" /><ref name="pmid22605909">{{cite journal| author=Goldenberg MM| title=Multiple sclerosis review. | journal=P T | year= 2012 | volume= 37 | issue= 3 | pages= 175-84 | pmid=22605909 | doi= | pmc=3351877 | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=22605909  }} </ref>

Overview

Neurosyphilis must be differentiated from other diseases that cause abnormal gait, Blindness, confusion and depression, such as multiple sclerosis, Brain tumours, Wernicke’s encephalopathy, CNS abscess, electrolyte disturbance, Subdural empyema, subarachnoid hemorrhage, brain stroke, Conversion disorder and Drug toxicity.

Differentiating X from other Diseases

  • Neuroyphilis has an extensive differential diagnosis.
Diseases Diagnostic tests Physical Examination Symptoms Past medical history Other Findings
Na+, K+, Ca2+ CT /MRI CSF Findings Gold standard test Neck stiffness Motor or Sensory deficit Papilledema Bulging fontanelle Cranial nerves Headache Fever Altered mental status
Neurosyphilis[3][4] Leukocytes and protein
  • CSF FTA-Ab -sensitive[5]
  • Unprotected sexual intercourse, STIs
  • History of multiple sexual partners.
Multiple sclerosis Oligoclonal bands of IgG on electrophoresis of cerebrospinal fluid MRI
Brain tumour[1][2] Cancer cells[7] MRI
  • Cachexia
  • Gradual progression of symptoms
Wernicke’s encephalopathy Normal History of alcohal abuse
CNS abscess
  • Contrast enhanced MRI is more sensitive and specific
Electrolyte disturbance or Depends on the cause
Subdural empyema Clinical assesment and MRI History of relapses and remissions
  • Blurry vision
Delirium tremens Clinical diagnosis
  • Alcohol intake
  • Sudden withdraw or reduction in consumption
Subarachnoid hemorrhage[8] Xanthochromia[9] CT scan without contrast[11][6] Trauma/fall
Stroke Normal CT scan without contrast TIAs, hypertension, diabetes mellitus
  • Speech difficulty
  • Gait abnormality
Viral encephalitis Clinical assesment
  • Tick bite
  • Mosquito bite
  • Viral prodome for several days
Herpes simplex encephalitis Clinical assesment History of hypertension
Drug toxicity
Conversion disorder Diagnosis of exclusion
Febrile convulsion Not performed in first simple febrile seizures Clinical diagnosis and EEG
  • Family history of viral illness or
