According to the conclusions of a new scientific study published in the latest issue of the top journal Science, it would appear that dyslexia is caused, at least in part, by a series of faulty neural connections between areas of the brain coding for auditory sensations, and speech.

If this discovery is verified by other studies, then it could finally put all contradicting theories on the origins and root causes of dyslexia to rest. Additionally, doctors may become able to use the new data for developing interventions targeted on these neural miscommunications.

In people with dyslexia, the standard connections that form in the human brain between components of spoken words and written symbols do not function properly, leading to issues in identifying written words or symbols correctly, Nature reports.

The new investigation was conducted at the Catholic University of Leuven in Belgium, and was led by clinical psychologist Bart Boets. The most important conclusion is that deficits in brain connectivity are the main reason why the phonetic representation of language cannot be accessed by dyslexics.
