ADHD in DSM-5: what did you think would happen?

"Our results, combined with previous findings, suggest a 27% increase in the expected prevalence of ADHD [attention-deficit hyperactivity disorder] among young adults, comparing DSM-IV to DSM-5 criteria". So said the paper by Matte and colleagues [1] who as part of their study looked at "the prevalence of ADHD according to DSM-5 criteria".

The changes to the diagnosis of ADHD in DSM-5 can be seen here. The main difference between DSM-IV and DSM-5 diagnosis seems to be a change in the maximum age of symptom onset; previously set at 7 years in DSM-IV, now 12 years in DSM-5. This change has been the topic of quite a bit of discussion [2].

I'm going no further in this discussion aside from bringing to your attention an article by Dr Allen Frances who has been more than a little critical of the changes made to DSM in this latest version. To quote: "DSM 5 will likely trigger a fad of Adult Attention Deficit Disorder leading to widespread misuse of stimulant drugs for performance enhancement and recreation and contributing to the already large illegal secondary market in diverted prescription drugs". Accepting that any rise in the use of nootropics is beyond the scope of this post, the increase in expected prevalence reported by Matte and colleagues is not a million miles away from Dr Frances' 2012 prediction...
