Hypoxia around the time of birth is a significant cause of death among preterm infants while survival is often associated with debilitating morbidity and lifelong disabilities such as learning difficulties, ADHD, and cerebral palsy.

Experiments have shown that hypoxic brain injury evolves exponentially over time. Fortunately, there is a latent phase window of opportunity during the first 3-6 hours after birth, in which the brain cells are still recoverable. Neuroprotective treatments such as therapeutic hypothermia (or brain cooling) are shown to be only effective to stop the spread of brain injury if started early on in this phase.

This study is focused on the development of automated advanced signal processing algorithms for precise identification of biological markers of Hypoxic brain injury that occur along high frequency sampled Electroencephalography (EEG) signals, post asphyxia at birth, right when the brain injury is still treatable.

So far, results of this research have advance impact by demonstrating where the occurrence of the automatically identified EEG markers correlate with subcortical brain damage. It has been substantiated where exactly in time is possible to optimally fight against the spread of brain injury. The key outcomes of his study will help clinicians to treat at-risk babies during which the neural injury is in its primitive levels and before it becomes irreversible.
