Early Prediction of Cognitive Deficit using Deep Learning and Brain Connectome

The high risk of neurodevelopmental impairments is a major concern for parents and clinicians caring for premature babies. Annually, approximately 22,000 very preterm infants (i.e. ≤32 weeks gestational age) in the United States develop cognitive deficits. Unfortunately, cognitive deficits cannot be reliably diagnosed until 3 to 5 years of age. There is a gap in our knowledge about early identification of infants at high-risk for cognitive deficits. This gap limits our ability to target early interventions to the highest risk infants during periods of optimal neuroplasticity to enhance their ability to reach their full intellectual potential.

The human brain is a highly interactive system that exhibits both structural and functional units/networks. Diffusion Magnetic Resonance Imaging (dMRI) and resting-state functional connectivity MRI (fcMRI) have made possible quantitative mapping of the connections within and between these networks. Scientists have dubbed this the brain connectome and it has opened a window for observing the human mind. Research supports the notion that cognitive deficits may result from a disturbance/breakdown in the connectome and that the brain connectome shows high variability among subjects. What is not yet known, is whether this variability can enable personalized clinical prediction of neurodevelopment. We propose to develop a robust machine learning framework that can analyze integrated structural and functional brain connectome data obtained at term corrected age to make predictions about cognitive outcomes at 2 years of age in very preterm infants.

We have evaluated our models using a very preterm infant cohort. Please contact the PI, Dr. Lili He at Lili.He@cchmc.org for further data inquiries.
