Improving Outcomes from CSF Shunting in People with Idiopathic Normal Pressure Hydrocephalus

Takeaway

  • Using a cerebrospinal fluid (CSF) tap test (TT) and standardized patient selection criteria may improve clinical motor and urinary outcomes from CSF shunting surgery in idiopathic normal pressure hydrocephalus (iNPH).

Why this matters

  • The gold standard for diagnosis and treatment of iNPH is clinical improvement after CSF shunting; however, there is variability in clinical outcomes, which may be due to patient selection and the method of outcomes measurement.

  • One way to improve patient selection may be by using a CSF TT; however, its role in predicting positive clinical outcomes, with a standardized methodology and outcomes measurement, is unknown.
