A role for dislexia in language evolution?

In a new paper Gabrieli highlight the recent results of cognitive neuroscience research on dyslexia and its potential consequences for the treatment of dyslexic children through educative measures.

What Gabrieli show is that dyslexia, an impairement in reading abilities linked to difficulties in phonological processing, can be detected very early on by brain imaging techniques and treated in some cases with specific training in reading during the beginning of learning. If left undetected and untreated, dyslexia can cause prolonged difficulties in reading abilities and decrease motivation to read.

Dyslexia and its orthographic consequences could be of great interest for cognition-and-culture oriented scientists because orthographic errors generated by dyslexia or other processes produce linguistic variation at the origin of language evolution.
