ADHD figures: How many children suffer from this disorder in Spain?

ADHD is one of the most common childhood disorders, although it is difficult to refer to exact figures since many cases are never diagnosed. In fact, even today, many people discover that they suffer from ADHD when they diagnose their children.

However, others believe that it is a problem of overdiagnosis, in which case there would be many children who In reality, they would not meet the criteria for having ADHD.

In this sense, the case of France is curious. According to a report published by the High Authority for Health, in this country the incidence of ADHD is 0.5%, a figure that is well below the world and European average. Why?

The explanation can be found in the diagnostic criteria that are applied. In the DSM-IV and the ICD-10, which are the main diagnostic manuals that have been in force in the world of Psychology and Psychiatry in recent years, the diagnostic criteria for ADHD are practically identical, but the same does not occur with the diagnostic codes. In fact, the DSM-IV only requires six symptoms of inattention or six symptoms of hyperactivity/impulsivity to reach a diagnosis, while the ICD-10 has a stricter diagnostic criteria, according to which at least six symptoms of inattention must be present, at least three of hyperactivity and at least one of impulsivity.
