Functional - iNPH Shunt Surgery: Pre-operative CSF Tap Test Impact on Outcomes

In this episode, we delve into the clinical characteristics and outcomes of shunt surgery for idiopathic normal pressure hydrocephalus (iNPH), specifically examining the role of pre-operative cerebrospinal fluid (CSF) tap testing. This discussion is based on a single-center follow-up study of 481 patients, published in Fluids and Barriers of the CNS in 2026. The full text of the study was reviewed to understand its retrospective design, patient cohort, and key findings regarding shunt placement with or without prior CSF tap testing. We will explore how the presence or absence of this test might influence post-surgical outcomes and clinical decision-making in managing iNPH.
