Diagnostic accuracy of CSF tap-test parameters in predicting shunt responsiveness in normal pressure hydrocephalus: a cohort study

Key Points

• This study aims to evaluate the diagnostic utility of the cerebrospinal fluid tap test in predicting outcomes after shunt surgery for normal pressure hydrocephalus.
• Cohort study design examining patients with idiopathic normal pressure hydrocephalus
• Assessment of the cerebrospinal fluid tap test parameters
• Evaluation of shunt surgery outcomes
• The diagnostic accuracy of CSF tap test parameters in predicting shunt responsiveness remains uncertain
• Further analysis indicates variability in shunt outcomes based on tap test results
