New AI system to evaluate brain maturity in preterm infants

London: In a first, scientists have developed an artificial intelligence (AI) system which can evaluate the maturity of a preterm infant’s brain, an advance that will help plan the best possible care for the baby.

Researchers at the University of Helsinki and the Helsinki University Hospital in Finland developed a software based on machine learning, which can independently interpret EEG signals from a premature infant and generate an estimate of the brain’s functional maturity.

In the study, published in the journal Scientific Reports, a large amount of EEG data on preterm infants was fed into a computer, and the software calculated hundreds of computational features from each measurement without intervention from a doctor.

With the help of a support vector machine algorithm, these features were combined to generate a reliable estimate of the EEG maturational age of the infant, researchers said.

The method is more precise than other currently understood methods of evaluating the development of an infant’s brain and enables the automatic and objective monitoring of a premature infant’s brain development.

“We currently track the development of an infant’s weight, height and head circumference with growth charts,” said Sampsa Vanhatalo from the University of Helsinki.

EEG monitoring combined with automatic analysis provides a practical tool for the monitoring of the neurological development of preterm infants and generates information which will help plan the best possible care for the individual child, Vanhatalo said.

“This method gives us a first-time opportunity to track the most crucial development of a preterm infant, the functional maturation of the brain, both during and after intensive care,” researchers said.
