New MRI method could spot reversible dementia more accurately

This study looked at 75 older adults with suspected normal pressure hydrocephalus, a condition that can cause a reversible form of dementia. Researchers used a combination of fluid infusion tests and special MRI scans to better understand how brain fluid and pressure interact. The goal was to create a new way to identify which patients would benefit from a shunt to drain excess fluid, improving diagnosis beyond current methods.
