Injury risk and ADHD: part 2

Consider this short post a sort of follow-on to a previous entry on this blog concerning the elevated risk of injury following a diagnosis of attention-deficit hyperactivity disorder (ADHD). The paper in question today is that by Wu-Chien Chien and colleagues [1] who yet again [2], brought the quite significant scientific weight of the "National Health Insurance Research Database in Taiwan" to bear on this topic.

In this latest paper, Chien et al relied on data from a 'subset' of the main insurance research database and found some not unexpected things: "The patients with ADHD had a 143% increased risk of overall injuries than the controls after considering all the confounding factors" and "the use of methylphenidate was associated with a 22.6% decrease in the risk of injuries in the patients with ADHD."

What's more to say? Well, yet again risk of adverse issues *correlating* with a diagnosis of ADHD comes to the forefront (see here for another example). Yet again the idea that 'tackling' ADHD is a worthy goal (for many reasons) if not only to mitigate such elevated risks being presented, bearing in mind that medication "approved solely for ADHD treatment" is not some sort of magic bullet [3]. There are also other potentially important intervention options to look at (see here for example). I'm minded at this point to also bring in the recent findings reported by Borschuk and colleagues [4] talking about how comorbid asthma accompanying ADHD (yes, there is a surprisingly strong relationship between the two diagnoses) might play a role in the expression of ADHD and onwards provide some 'interesting' directions when it comes to tackling ADHD and it's elevated risk for various adverse outcomes...

To close, appreciating a talent...
