Study Aims to Improve Dyslexia Treatment

Neuroscientist Sarah Laszlo wants to understand what’s going on in children’s brains when they’re reading. Her research may untangle some of the mysteries surrounding dyslexia and lead to new methods of treating America’s most common learning disorder.

“The brain can reveal things that aren’t necessarily visible on the surface,” she says. “It can tell you things about what’s going wrong that you can’t find out by giving a kid a test or asking him to read out loud.”

Laszlo, who joined Binghamton’s psychology department in 2011, recently received a five-year, $400,763 grant from the National Science Foundation’s Early Career Development (CAREER) Program, the agency’s most prestigious award for young researchers. The funding will enable her to conduct a five-year brain activity study of 150 children with and without dyslexia.

Rather than lumping all children with dyslexia into one group, as many previous brain-imaging studies have done, Laszlo’s project will help to establish types and degrees of the disorder.

Her lab uses electroencephalography, or EEG, as a non-invasive way to measure the electrical signals sent between brain cells when they’re communicating with each other. Study participants — kids in kindergarten through fourth grade — wear a cap outfitted with special sensors while playing a computerized reading game.

These scans produce massive amounts of data: The cap’s 10 sensors collect readings 500 times per second for 45 minutes. That’s one reason that brain activity studies are expensive and time-consuming. It’s also the reason that a study of just 150 children is the largest study of its kind.

Kara Federmeier, a professor of psychology at the University of Illinois, says it’s not just the scale of the study that’s impressive; it’s also the project’s duration. “Sarah will be able to assess how the brain transitions from immature reading processes to mature reading processes,” Federmeier says. “Her project promises to provide important, novel data that may be critical for informing educational practices about teaching reading and clinical practices for assessing reading-related difficulties.”

Why study this disorder in particular? Laszlo notes that there are significant, sometimes lifelong consequences of growing up with dyslexia. Many dyslexic children don’t do as well in school as they might otherwise, which limits their career opportunities. Some also encounter social problems. “This has the potential to help a lot of people,” she says.

Laszlo hopes to identify the brain signatures of people with dyslexia and have a clear idea of how to help them. “Once you understand what’s going on in the brain,” she says, “you can do a better job of designing treatments.”

Today, the best-case scenario is that children with dyslexia receive interventions that enable them to get up to speed on reading aloud. But they may continue to lag behind their peers when it comes to comprehension, fluency and speed. “The treatments we have now don’t always fix the underlying problem,” Laszlo says. “They just put a Band-Aid on it. And when you go to do more complicated things, like reading larger passages, the Band-Aid doesn’t help.”
