A Common Reading Disorder

There are SO MANY reasons a child may not be able to read!  Sometimes as parents and educational consultants, we stop at the diagnosis of a reading disorder and do not go the next step to try and determine the underlying causes of the reading difficulty.  This is a good article in that it talks about a very common reading disorder:  often kids can understand how to read the letters (ornithological processing), can sound out sounds (phonological processing) and can read sentences well.  It is easy to think the child is “reading” well, but sometimes they are reading but not able to comprehend what they are reading.  Issues can relate to slower processing speed, poor working memory, and any number of other issues, such as ADHD or auditory processing issues.  The strong advice we give at The Price Group is to go the next step:  find a qualified reading specialist that can go beyond a diagnosis and be more prescriptive as to what exact types of remediation and tutoring will help your child succeed!

Not all reading disabilities are dyslexia

Lesser-known reading disorder can be easily missed

A common reading disorder goes undiagnosed until it becomes problematic, according to the results of five years of study by researchers at Vanderbilt’s Peabody College of education and human development in collaboration with the Kennedy Krieger Institute/Johns Hopkins School of Medicine. Results of the study were recently published online by the National Institutes of Health.

Dyslexia, a reading disorder in which a child confuses letters and struggles with sounding out words, has been the focus of much reading research.

But that’s not the case with the lesser known disorder Specific Reading Comprehension Deficits or S-RCD, in which a child reads successfully but does not sufficiently comprehend the meaning of the words, according to lead investigator Laurie Cutting, Patricia and Rodes Hart Chair at Peabody.

When a child is a good reader, it’s assumed their comprehension is on track. But 3 to 10 percent of those children don’t understand most of what they’re reading.“S-RCD is like this: I can read Spanish, because I know what sounds the letters make and how the words are pronounced, but I couldn’t tell you what the words actually mean,” Cutting said. “When a child is a good reader, it’s assumed their comprehension is on track. But 3 to 10 percent of those children don’t understand most of what they’re reading. By the time the problem is recognized, often closer to third or fourth grade, the disorder is disrupting their learning process.”

Researchers have been able to pinpoint brain activity and understand its role in dyslexia, but no functional magnetic resonance imaging or fMRI studies, until now, have examined the neurobiological profile of those who exhibit poor reading comprehension despite intact word-level abilities.

Neuroimaging of children showed that the brain function of those with S-RCD while reading is quite different and distinct from those with dyslexia. Those with dyslexia exhibited abnormalities in a specific region in the occipital-temporal cortex, a part of the brain that is associated with successfully recognizing words on a page.

But those with S-RCD did not show abnormalities in this region, instead showing specific abnormalities in regions typically associated with memory.

“It may be that these individuals have a whole different neurobiological signature associated with how they read that is not efficient for supporting comprehension,” Cutting said. “We want to understand the different systems that support reading and see which ones help different types of difficulties, and how we can target the cognitive systems that support those skills.”

The study, an ongoing 10-year effort supported by National Institutes of Health grant No. M01-RR000052, has enrolled more than 300 children to date.
