About 10 percent of the U.S. population suffers from dyslexia(阅读障碍), a condition that makes learning to read difficult. Dyslexia is usually diagnosed1 around second grade, but the results of a new study from MIT could help identify those children before they even begin reading, so they can be given extra help earlier. The study, done with researchers at Boston Children's Hospital, found a correlation2 between poor pre-reading skills in kindergartners and the size of a brain structure that connects two language-processing areas.
 
Previous studies have shown that in adults with poor reading skills, this structure, known as the arcuate fasciculus(纤维束), is smaller and less organized than in adults who read normally. However, it was unknown if these differences cause reading difficulties or result from lack of reading experience.
 
"We were very interested in looking at children prior to reading instruction and whether you would see these kinds of differences," says John Gabrieli, the Grover M. Hermann Professor of Health Sciences and Technology, professor of brain and cognitive3 sciences and a member of MIT's McGovern Institute for Brain Research.
 
Gabrieli and Nadine Gaab, an assistant professor of pediatrics at Boston Children's Hospital, are the senior authors of a paper describing the results in the Aug. 14 issue of the Journal of Neuroscience. Lead authors of the paper are MIT postdocs Zeynep Saygin and Elizabeth Norton.
