The problem is that the number of children being diagnosed with ADHD seems dubious(I accept that there's real cases). According to the stats in[1] 20% of boys aged between 14-17 have been diagnosed at some point with ADHD. When you're diagnosing 20% of the male population with a condition isn't it time to accept that it isn't a condition, rather it's within the normal range of behaviour (many of the symptoms would be simply be considered an aspect of one's personality in other times).
