Dyslexia is typically diagnosed in children when they are
around second or third grade in school. A team from Children’s Hospital Boston
reports that they have discovered signs of dyslexia in children as young as 4
or 5 years old by studying their brain scans. This could be monumental news for
families, who "often know that their child has dyslexia as early as
kindergarten but they can’t get interventions at their schools," says Nadine
Gaab of the Laboratories of Cognitive Neuroscience at Children’s.
Early intervention would be ideal in cases of dyslexia.
Rather than waiting for a child to exhibit reading delays, a diagnosis before
the child even begins to learn to read could boost confidence and help them
avoid the label of being a "poor student." As Gaab said in an interview with
Reuters, "Often, by the time they get
a diagnosis, [children] usually have experienced three years of peers telling
them they are stupid, parents telling them they are lazy. We know they have
reduced self esteem. They are really struggling."
In the Children’s
Hospital study, a group of 36 preschoolers had their brains scanned by Gaab and
her colleagues while they did a variety of tasks that deal with phonological
processing. Phonological processing is the ability to recognize and manipulate
the individual sounds that form language. Children with dyslexia have trouble
with mapping sounds of spoken language onto letters that make up words. According
to Gaab, the study shows that children who had a family history of dyslexia did
not use the area of their brains typically used for processing this
information.
Gaab explains
that her study is too small at the moment to form the basis for any test for
dyslexia. She and her team have just received a grant from the National
Institutes of Health to do a larger study. Ultimately, she
says, "If we can show that we can identify these kids early, schools may be
encouraged to develop programs." In the meantime, parents can go to their
pediatricians and ask for their child to be assessed for signs of early
dyslexia.
