Explican que utilizando resonancia magnética de alta resolución han hallado diferencias en áreas del cerebro relacionadas con la atención y con el control de impulsos en niños con el trastorno.
"Estos hallazgos pueden ayudarnos a comprender mejor la acción de las medicaciones utilizadas para tratar el THDA, en particular los fármacos estimulantes", señalan los autores.
Compararon las imágenes de la resonancia magnética tras someter a esta prueba a 27 niños y adolescentes con THDA y a 46 controles. Los investigadores explican que "los cambios no sólo se encuentran en las regiones del cerebro que controlan la atención, sino también en las regiones que favorecen el control de los impulsos, ya que un control trastornado de los impulsos es a menudo el síntoma clínicamente más debilitante en niños con THDA.
