Brain mapping may predict preemies at risk of disabilities
Scanning a premature infant’s brain shortly after birth may help doctors better predict whether the baby will develop disabilities later, a new study has found. Lack of oxygen to the brain is the most common form of brain injury in premature infants, resulting in damage to the White matter contains nerve fibres that maintain contact between various parts of the brain. Damage to white matter can interfere with communication in the brain and the signals it sends to other parts of the body. “Babies who are born before 31 weeks gestation have a higher risk of thinking, language and movement problems throughout their lives, so being able to better predict which infants will face certain developmental problems is important so they get the best early interventions possible,” said Steven P Miller from The Hospital for Sick Children in Canada.

For the study, researchers looked at a group of premature infants who were admitted to the Neonatal ICU at British Columbia’s Women’s Hospital over seven years. They found 58 babies with white matter injury who had an MRI brain scan at an average of 32 weeks after gestation. These babies were then evaluated for motor, thinking and language skills when they were 18 months old. Researchers found that a greater volume of small areas of injury, no matter where they were located in the brain, could predict movement problems at 18 months. They also found that a greater volume of these small areas See what else is making news in lifestyle, here The findings from the study highlight the importance of injury location when considering developmental outcomes. For example, premature infants with larger frontal lobe injuries had a 79 fold greater odds of developing thinking problems than infants without such injuries, as well as a 64 fold greater odds of problems with movement development. Miller said that future studies should evaluate premature infants not just at 18 months, but at various points throughout childhood to determine the long-term consequences of early injuries in the brain. The study was published in the journal Neurology.
