N2 - Objective This functional magnetic resonance imaging (fMRI) study examined how working memory circuits are affected by face emotion processing in pediatric bipolar disorder (PBD) and attention-deficit/hyperactivity disorder (ADHD). Methods A total of 23 patients with PBD, 14 patients with ADHD, and 19 healthy control (HC) subjects (mean age, 13.36 ± 2.55 years) underwent an affective, two-back fMRI task with blocks of happy, angry, and neutral faces. Results For angry versus neutral faces PBD patients, relative to ADHD patients, exhibited increased activation in the subgenual anterior cingulate cortex (ACC) and orbitofrontal cortex, and reduced activation in the dorsolateral prefrontal cortex (DLPFC) and premotor cortex. Relative to the HC group, the PBD group showed no increased activation and reduced activation at the junction of DLPFC and ventrolateral prefrontal cortex (VLPFC). Relative to HC, the ADHD patients exhibited greater activation in the DLPFC and reduced activation in the ventral and medial PFC, pregenual ACC, striatum, and temporo-parietal regions. For happy versus neutral faces, relative to the ADHD group, the PBD group exhibited greater activation in the bilateral caudate, and relative to the HC group the ADHD group showed increased activation in the DLPFC, striatal, and parietal regions, and no reduced activation. The ADHD group, compared with the HC group, showed no reduced activation and increased activation in regions that were underactive for the angry face condition. Conclusions Relative to the ADHD group, the PBD group exhibited greater deployment of the emotion-processing circuitry and reduced deployment of working memory circuitry. Commonalities across PBD and ADHD patients, relative to the HC individuals, entailed cortico-subcortical activity that was reduced under negative emotional challenge and increased under positive emotional challenge.
