Sydney: Teenagers born prematurely may suffer from brain development problems due to low levels of cortisol - a hormone that plays a critical role in memory and learning abilities, according to an Australian study.University of Adelaide researchers have demonstrated that teenagers born prematurely, that is before the 37th week, may suffer from such deficiencies.The research, conducted by Julia Pitcher and Michael Ridding from the University of Adelaide`s Robinson Institute, shows reduced `plasticity`, the brain`s ability to change and adapt when it learns or experiences something new, in teen-agers born premature, the Journal of Neuroscience reports."Pre-term teens also had low levels of cortisol in their saliva, which was highly predictive of this reduced brain responsiveness," says Pitcher, according to an Adelaide statement.
