At present the diagnosis of the disorder hyperactivity is characterized by a persistent pattern of inattentive, is considered basically clinical (NICE, 2009) and is usually restless and impulsive behavior which is more frequent and accompanied by questionnaires to parents and teachers, such as severe than that typically observed in subjects at a similar stage those previously mentioned. These questionnaires usually have a of development. ADHD symptoms should have an onset before cut-off point that allows people to be deemed within or outside the age of 7, persist for at least six months to a degree which is the clinical range and can lead to different estimates depending maladaptive and inconsistent with the developmental level, and on their use. The authors think that the validity of the criteria and give rise to a clinically signifi cant impairment in social, academic clinical usefulness of these questionnaires may vary according to or occupational functioning and some of the alterations caused the method used and the age range. by these symptoms should be present in at least two of these Our study will provide new fi gures on the prevalence of settings.

Therefore, the main objective of our research is to study A recent prevalence study has found that the extension of the the criterion validity and clinical usefulness of ADHD RS- criterion on the age of onset of 7 to 12 years led to an increase IV depending on the procedure used to defi ne ADHD (parent in the prevalence rate of ADHD from 7.4% (DSM-IV) to 10.8% response, teacher response, parent-teacher responses and their (DSM-5). However, young people with a later onset age did not use in childhood (6-9 years), preadolescence (10-13 years) or differ from those with earlier onset in terms of severity and adolescence (14-16 years). comorbidity patterns, although they were more likely to belong to low-income families and ethnic minorities (Voort, He, Jameson, Method & Merikangas, 2014). A global systematic review of prevalence studies in childhood Participants and youth ADHD observed an average of 5.29% (Polanczyk, de Lima, Horta, Biederman, & Rohde, 2007). Our research is posed as a population study to evaluate the Recent meta-analysis studies on the prevalence of ADHD, prevalence of ADHD in Castile and Leon (Spain).
