I think this answers that last question, about which area's of brain are affected
WASHINGTON, DC—
Between 5% and 15% of babies born prematurely later display major spastic motor deficits suggesting cerebral palsy. “Even more concerning is that between 25% and 50% of these infants will exhibit a broad range of developmental disabilities,” emphasized Terrie E. Inder, MD. Dr. Inder is a visiting scientist at Children’s Hospital in Boston and an Associate Professor at the University of Melbourne in Australia.
Suspecting that premature infants might have brain structure alterations relative to healthy term infants, Dr. Inder and colleagues used an advanced form of magnetic resonance imaging (MRI) to compare the two groups’ brain structures. “Based on previous neuropathologic and conventional data, we anticipated finding alterations principally in white matter structures,” Dr. Inder said. What she and her group discovered, however, was that the most striking differences between premature and term infants were in cortical gray matter, she related in her presentation at the 31st Annual Meeting of the Child Neurology Society.
