This trial is testing a diagnostic device called ShuntCheck to see if it can reliably tell whether a ventriculoperitoneal shunt (a tube that drains fluid from around the brain) is working correctly. The device is being tested in patients who have normal pressure hydrocephalus and already have a shunt in place. Researchers want to know if ShuntCheck can accurately detect whether fluid is flowing through the shunt or if it's blocked.
Currently, doctors sometimes have difficulty determining whether a patient's shunt is working without doing invasive tests or imaging studies. This trial exists to see if ShuntCheck could become a simpler, faster way to check shunt function during routine office visits.

If you join this study, you will have the ShuntCheck test performed during a routine care visit at the University of South Florida. The test is non-invasive and involves placing a device over your shunt to check if fluid is flowing through it. The entire process is relatively quick and happens as part of your regular follow-up appointment.
