Within the past week, new research was announced that found a new marker for dyslexia in children.

Northwestern University researchers have published their research detailing a biological feature that plays an important role in reading—an area in which dyslexics struggle.

BREAKING: Researchers Find New Marker of Dyslexia in Children

The article, published in The Journal of Neuroscience, discusses the relationship between a child’s success in reading and how he or she encodes sounds. The study recorded 100 students’ automatic brain wave responses to speech sounds and found that the most successful readers encoded the sounds consistently while the least successful readers encoded most inconsistently.

Though this discovery shows that children who struggle most with reading can’t consistently encode speech sounds, the authors of the article—Jane Hornickel and Nina Kraus—say it can be ‘fixed’ through training. Students that used assistive listening devices were more likely to show improvement in reading.

"Use of the devices focused youngsters’ brains on the ‘meaningful’ sounds coming from their teacher, diminishing other, extraneous distractions," said Kraus. "After a year of use, the students had honed their auditory systems and no longer required the assistive devices to keep their reading and encoding advantage."
