Wearable sensor shows link between blood pressure and intracranial pressure
Brazilian researchers have simultaneously demonstrated the mechanism that links high blood pressure with increased intracranial pressure, validated a non-invasive method of monitoring intracranial pressure, and proposed a treatment for high blood pressure that does not affect intracranial hypertension. The study was supported by FAPESP and involved a collaboration between researchers from São Paulo State University (UNESP) and Brain4care, a startup based in São Carlos. It could lead to novel treatments for intracranial hypertension and its complications, including stroke. The main results are reported in the journal Hypertension. The researchers monitored blood pressure and intracranial pressure in rats for six weeks. “We wanted to investigate what happened to the intracranial pressure during the time when the animals became hypertensive. We were the first to succeed in monitoring this process non-invasively by tracking changes in the shape of the intracranial pressure curve. ...
