Normal pressure hydrocephalus, also known as Adams and Hakim syndrome, is a relatively uncommon disease, however, it is currently of great relevance because it is directly associated with reversible dementia. The most frequent clinical triad includes gait disorders, dementia and urinary incontinence. Ventricular bypass surgery is still the procedure of choice in most cases, and, as with any surgery, it is not free of complications, and system revision may be necessary in up to 20% of cases.
How did the sensor help?
The method contributed to the diagnosis of normal pressure hydrocephalus at the AMBULATORY level, in a non-invasive way, in the doctor’s office, avoiding hospitalization. Subsequent examination of the patient showed that there was indeed a need for ventriculoperitoneal (VP) shunt implantation. In view of this, it allowed assertiveness in conduct, avoiding previous, unnecessary procedures.
Patient with suspected normal pressure hydrocephalus, monitored during the TAP test. Initially, the b4c method showed reduced compliance, which improved after puncture with 20 ml of CSF drainage, as can be seen in the figures below.
