Torres I, et al. - Physicians designed this study to evaluate the neurocognitive profile of a comorbid group [bipolar disorder (BD)+attention-deficit hyperactivity disorder (ADHD)] compared with that of pure BD (pBD) group, pure ADHD (pADHD) group and healthy controls (HCs). Although preliminary, the outcomes proposed that the BD+ADHD group indicated the same neurocognitive profile as pBD patients, most likely reflecting the same neurobiological basis. In contrast, the pADHD group demonstrated a more selective moderate impairment in attention.
