Standardized protocol for assessing idiopathic normal pressure hydrocephalus improves outcomes


  • A standardized protocol, including high-volume lumbar puncture (HVLP), for the assessment of patients with suspected idiopathic normal pressure hydrocephalus (INPH), potentially allows improvement in the prediction of positive ventriculoperitoneal shunting (VPS) outcomes and in the selection of patients who will benefit from the surgical procedure.

Why this matters

  • The assessment for INPH can be difficult to coordinate and the prediction of patients who will benefit from VPS can be challenging.

  • This study assessed the implementation of a formalized protocol for INPH patient care, and showed that this protocol can improve patient selection for VPS.
