Just came across this:

Sleep consolidates emotional memories in healthy children but not those with ADHD

Sleep consolidates emotional memories in healthy children but not in children with attention-deficit hyperactivity disorder (ADHD), according to research published May 29 in the open access journal PLOS ONE by TK and colleagues from TK. The study suggests these deficits in sleep-related emotional processing may exacerbate emotional problems experienced in the daytime by children with ADHD.

For the study, healthy adults, healthy children and children with ADHD were shown pictures that had emotional relevance, such as a scary animal, or neutral pictures showing an umbrella or lamp. Participants were shown pictures in the evening, their brain activity was monitored as they slept, and recollections were tested the following morning. The researchers found that during sleep, regions of the brain thought to support consolidation of emotional memories were most active in healthy children, less so in healthy adults and least active in children with ADHD.

The study states, "While several studies reported a benefit from sleep with respect to emotional memory in healthy individuals, our results showed for the first time that healthy children outperform healthy adults."

Interesting, since emotional issues, as I understand it, aren't officially a symptom of ADHD. Looking at the study method though, can't help but wonder if the ADHD children just didn't pay attention to the pictures in the first place.

I'm going to have to take a look at the paper, because the information in this article doesn't seem to present anything cohesive or relevant. I don't know what the point is supposed to be! The link to the research is here ( for anyone else who wants to try to plow through it. The paper has a lot more focus on the ADHD aspect of the research than the article did. I'll reserve comment for after I've digested the whole thing.
