[Attention deficit hyperactivity disorders: current controversy regarding definition, epidemiology, etiology and treatment].

In this paper a review of the current literature is carried out to provide information of consensus and divergence points from the Scientific Community, about interesting questions in the hyperactivity disorder. The core and traditionally debated questions are boarded, including the concept, assessment, prognosis and etiology to finish up with the comment concerning the treatment approaches. It's a concluded that although there aren't definitive answers, the different approaches of conceptualization are getting closer, a better understanding of neurobiological disorder basis, and the need of facing its assessment and treatment from multidisciplinary and multi-methodological assumptions is taking place.
