Prospective Study of the Feasibility of Brain Connectivity Imaging by Functional Ultrasound Imaging (fUS) in Newborn Infant

Neurodevelopmental disorders (NDD) affect how the brain develops and can lead to lifelong difficulties with movement, learning, behavior, and thinking. Every year, around one million newborns in Europe are affected by these conditions. Some babies are at higher risk of NDD due to factors such as being born extremely premature, having poor growth in the womb, experiencing a lack of oxygen at birth, or having a family history of severe NDD. However, predicting which babies will develop these disorders is currently very challenging because there are no reliable early indicators (biomarkers) to detect them. The CONEXUS study is testing a new type of brain imaging technology called functional ultrasound imaging (fUS) to see if it can help assess brain function in newborns at high risk of NDD. This technique measures brain activity by detecting small changes in blood flow, similar to an ultrasound scan but using advanced imaging technology. Researchers believe this method, known as fC-fUS imaging, could help identify early signs of neurodevelopmental disorders. Preliminary studies have shown that fUS imaging can detect brain activity changes in newborns, such as differences between sleep states or during epileptic seizures. The CONEXUS study will expand on this by improving the imaging technology and testing it in a larger group of newborns, including those born prematurely, those with restricted growth, those who needed cooling treatment after birth due to lack of oxygen, and th…
