  • Incontinence

Differential Diagnosis

  • Alzheimers
  • Stroke
  • Parkinson's Disease
  • Electrolyte abnormality
  • Malignancy
  • Uremic encephalopathy
  • Hydrocephalus ex vacuo (diffuse cerebral atrophy on CT)

Evaluation

  • CBC
  • Chem 7
  • LP: normal opening pressure
    • Symptom improvement supports diagnosis[1]
  • CT brain

Management

  • Additional work up warranted for surgical candidate[1]
