A technology developed by the Brazilian company brain4care has been shown to be able to measure absolute values of intracranial pressure (ICP) more accurately than existing non-invasive methods. This is the result of a study published in the journal npj Digital Medicine by researchers from the University of São Paulo in Brazil, the University of Cambridge in the United Kingdom, Emory University in the United States, and the company itself.

“The study included the largest number of patients and showed that the technology we developed had the lowest error in estimating the value of intracranial pressure among all the non-invasive methods already available in the world,” Gustavo Frigieri, scientific director of brain4care and one of the authors of the study, told Agência FAPESP.

The technology developed by the Brazilian company consists of a sensor placed on the patient’s head that registers the nanometric expansions of the skull in each cardiac cycle and generates, in real time, a wave that indicates the variations in volume and intracranial pressure. The data obtained are processed by an artificial intelligence platform that generates reports to help doctors make decisions.
