Problems in hearing underlies dyslexia

Researchers have found that people with dyslexia have a problem processing sounds and decode them in their brain.

The condition is being highlighted as the cause of this disability and while it has not before been directly linked it is now thought that a specific abnormality in the processing of auditory signals accounts for the main symptoms of dyslexia.

A team of researchers at the Ecole Normale Supérieure in Paris, France, found that typical brain processing of auditory rhythms associated with phonemes was disrupted in the left auditory cortex of dyslexics meaning that people with the condition struggle with processing words they read.

Dr. Anne-Lise Giraud, part of the team at the institute, said: "Taken together, our data suggest that the auditory cortex of dyslexic individuals is less fine-tuned to the specific needs of speech processing."

It is estimated that there are two million people in the UK alone that are dyslexic with 375,000 in schools across the country.
