Abstract
El trastorno por déficit de atención e hiperactividad, es una patología que ha impactado al mundo desde hace casi 20 años, el diagnostico sigue siendo clínico, al no existir una prueba biológica, fisiológica o de imagen que confirme el diagnóstico. El electroencefalograma es un estudio que se realiza en esta patología, pero es inespecífico ya que cerca del 80 % de los estudios son normales y el resto anormal, nosotros encontramos que cerca de la mitad de los estudios de electroencefalografía mostraron un patrón anormal, entre los cuales destaca el epileptiforme o irritativo, por lo tanto el beneficio de realizar al niño un electroencefalograma no radica en confirmar el diagnostico, sino en descartar otras patologías asociadas, que comparten ciertas características conductuales.
Attention deficit disorder and hyperactivity are pathologies that have impacted the world almost 20 years ago. Diagnosis is still clinical, since there are no biological, physiological or image tests that may confirm the diagnosis. An electroencephalogram is a test that is often used in these case but the results are not definitive because almost 80% of the studies are normal and the rest abnormal. We found that close to half of the Electroencephalograms showed an abnormal pattern, among which was epileptiform or irritative activity, therefore the benefit of an electroencephalogram does not lie in confirming the diagnosis but in ruling out other associated pathologies sharing certain characteristics.
