Combining tests and scans to improve diagnosis and surgery decisions in idiopathic normal pressure hydrocephalus

Integrated Multimodal Approach for Diagnostic Optimization and Surgical Candidate Selection in Idiopathic Normal Pressure Hydrocephalus: The Role of CSF Biomarkers, Cognitive-Motor Assessment, and Neuroimaging

Observational Fondazione IRCCS Ca' Granda, Ospedale Maggiore Policlinico · NCT07427836

This project will try combining memory and gait tests, spinal fluid markers, and brain MRI to see if that helps identify people over 60 with suspected iNPH who are likely to benefit from shunt surgery.

What this trial studies

This is an observational cohort at a tertiary referral center enrolling people aged 60+ referred for suspected idiopathic normal pressure hydrocephalus. Participants undergo routine clinical data collection including standardized neuropsychological testing, motor and gait assessments before and after a CSF tap test, cerebrospinal fluid biomarker analysis, and brain MRI. Patients who proceed to CSF shunt surgery are compared with those given an alternative diagnosis and managed without surgery to examine differences in clinical, biomarker, and imaging features. Secondary analyses relate multimodal changes to surgical outcomes, including clinical response around six months when available.

Who should consider this trial

Good fit: People aged 60 or older with suspected iNPH who are referred to the center's standardized diagnostic pathway and can give informed consent are eligible.

Not a fit: Patients who have an alternative diagnosis (for example advanced Alzheimer's disease or other neurodegenerative/vascular conditions) or who are not surgical candidates are less likely to benefit from the findings.

Why it matters

Potential benefit: If successful, the approach could help doctors pick the right patients for shunt surgery and reduce delayed or unnecessary procedures.

How similar studies have performed: Previous work has shown that CSF tap tests, gait and cognitive measures, MRI features, and some CSF biomarkers can partly predict shunt response, but integrated multimodal prediction has not been fully validated.
