Modern techniques of brain imaging may help predict how svilupperenno reading disorders in adolescents with an accuracy of up to 90% :
much more than is normally achieved with today's diagnostic reading test.
The data collected are of the research published on "Proceedings of the National Academy of Sciences " Bruce McCandliss, a professor of psychology at Vanderbilt University in Nashville .
They subjected 45 young people between 11 and 14 years (25 of whom had been diagnosed as dyslexic), two types of brain imaging (magnetic resonance imaging and display "on the diffusion tensor), and performed tests of reading.
On average during the test, the dyslexic children showed, compared to the other, greater activation in right inferior frontal gyrus, a brain region near the right temple.
Two and a half years away the 13 guys in the group of dyslexics showed greater activation were also those who were compensated more noise, and read better than other dyslexic group.
Using data collected con le visualizzazioni nella prima fase di studio con modelli matematici, gli scienziati sono riusciti a simulare con grande precisione la prestazione che i ragazzi avevano mostrato a distanza di anni.
Gli autori della ricerca sperano che in questo metodo possa in futuro orientare le tecniche di intervento con cui oggi si cerca di migliorare le strategie di lettura nei giovani dislessici.
