Areas of working memory activation differ between pediatric bipolar disorder (BD) and attention-deficit/hyperactivity disorder (ADHD), according to new research. A small functional magnetic resonance imaging (fMRI) study showed that youths with BD used more of the limbic brain network and those with ADHD used more of their fronto-subcortical network during working memory tasks.

Robert M. Post, MD, director of the Bipolar Collaborative Network in Bethesda, Maryland, told Medscape Medical News, “It would be very interesting to see if they can turn this thing around and use it as a predictor. Whether the findings are robust enough to do that, I’m not sure. But it would be extremely helpful because you treat ADHD and bipolar so oppositely.”
