Brief Summary

Normal pressure hydrocephalus (NPH) is a preventable and treatable cause of dementia. However, as a nosological entity, it is significantly underdiagnosed, often being mistakenly classified as presenile or senile dementia without further investigation. Ongoing management is crucial, currently relying mainly on indirect methods-clinical and imaging-based. Telemetry offers a real-time, online method to assess actual cerebrospinal fluid pressures, which are crucial for patient management. Telemetry allows for tailoring treatment to the individual patient. This project is planned as a pilot study before a more extensive research project.

Detailed Description

Normal pressure hydrocephalus (NPH) is a preventable and treatable cause of dementia. However, as a nosological entity, it is significantly underdiagnosed, often being mistakenly classified as presenile or senile dementia without further investigation. Diagnosing NPH is not straightforward; it is based on a series of examinations, the results of which determine whether the patient is a responder and therefore a candidate for shunt surgery (implantation of a ventriculoperitoneal shunt). The medical literature identifies additional criteria that predict whether the implantation of the shunt will have a good or poor effect. However, treatment from a neurosurgical perspective does not end there. Ongoing management is crucial, currently relying mainly on indirect methods-clinical and imaging-based. Telemetry offers a real-time, online method to assess actual cerebrospinal fluid pressures, which are crucial for patient management. Telemetry allows for tailoring treatment to the individual patient. This project is planned as a pilot study before a more extensive research project.
