Los niños con retraso del habla tienden a escuchar con el hemisferio cerebral derecho, en lugar de hacerlo con el izquierdo, de acuerdo a una reciente investigación cuyos resultados preliminares habían sido presentados en el Congreso Anual de Radiología en EE.UU. en el 2002.
Los investigadores analizaron la RMN funcional de 17 niños con retraso en el habla y la compararon con 35 niños normales. Encontraron que los niños con severos retrasos del habla tendían a usar el hemisferio izquierdo, a diferencia de los niños normales que utilizaban el derecho. Además, los niños de 4 años y más con retraso del habla presentaban una actividad cerebral total inferior a los niños normales.
El Dr. Altman, responsable del trabajo, comentó que el siguiente paso será expandir el estudio y desarrollar test confiables para el diagnóstico y evaluación de los retrasos en el habla.
