Researchers found that PIP2 acts as a brake on Piezo1, a pressure sensor in brain vessels. In Alzheimer’s-model mice, low PIP2 led to Piezo1 overactivation and disrupted brain blood flow, but restoring PIP2 largely normalized flow, suggesting a potential new therapeutic target for dementia—though findings are early and based on mouse studies.
Engineers at UC San Diego have developed a wearable ultrasound patch that provides continuous, non-invasive monitoring of cerebral blood flow. This innovative device, which can be comfortably worn on the temple, offers three-dimensional data and overcomes the limitations of traditional transcranial Doppler ultrasound. The patch has been tested on healthy volunteers and plans are underway to test it on patients with neurological conditions.
