La investigación también señala que la mitad de niños diagnosticados tiene problemas de aprendizaje. "Estos resultados muestran que el THDA y los problemas de aprendizaje se encuentran entre las enfermedades crónicas más frecuentes que afectan a niños en edad escolar en Estados Unidos", escriben los autores.
Los datos se desprenden de encuestas realizadas a familiares de más de 8.600 niños entre 1997 y 1998.
