Objective@#This study aimed to compare the efficacy and safety of atomoxetine (ATX) and OROS methylphenidate (MPH) as adjunctive to selective serotonin reuptake inhibitors (SSRIs) in adults with attention-deficit hyperactivity disorder (ADHD) with comorbid partially responsive major depressive disorder (MDD). @*Methods@#Sixty Korean adults with ADHD and comorbid partially responsive MDD were recruited in a 12-week, randomized, rater-blinded, active-controlled trial and were evenly randomized to ATX or OROS MPH treatment. @*Results@#Depressive symptoms measured using the Hamilton Depression Rating Scale and Clinically Useful Depression Outcome Scale, and ADHD symptoms measured using the Adult ADHD Self-Report Scale, as well as the Clinical Global Impression-Severity, Clinical Global Impression-Improvement, and the Sheehan Disability Scale scores were significantly improved in both groups during the 12 weeks of treatment. The changes in all outcome measures during the 12-week treatment were not significantly different between the two groups (all p > 0.05). No serious adverse events were reported and there were no significant differences in systolic and diastolic blood pressure, pulse rate, weight, or body mass index between the ATX and MPH groups. @*Conclusion@#Our findings suggest that ATX and MPH can be used as adjunctive treatments in adults with ADHD and comorbid partially responsive MDD. The efficacy and tolerability of ATX and MPH in adults with ADHD did not differ significantly. Further studies should be conducted to draw a definitive conclusion.

Objective@#Childhood trauma is the most important environmental factor for several psychiatric disorders. Depressed patients with childhood trauma appear to have severe symptoms that frequently recur. This study investigated whether depressed patients with childhood trauma showed attenuated Nogo event-related potentials (ERPs) and source activity during response-inhibition tasks. @*Methods@#Forty-four patients patients with major depressive disorder (MDD) were instructed to perform a Go/Nogo task during electroencephalography. Sensors and source activities of N2 and P3 of the Nogo ERPs were analyzed. The participants’ clinical symptoms were assessed using the Childhood Trauma Questionnaire (CTQ), Beck Depression Inventory, State-Trait Anxiety Inventory, Barratt Impulsivity Scale, and Affective Lability Scale. The participants were divided into two groups (low and high), based on their total CTQ scores. @*Results@#MDD subjects with high CTQ scores showed significantly decreased Nogo P3 amplitudes at the frontal, frontocentral, central, and parietal electrodes than those with low CTQ scores (all p < 0.01). In Nogo P3, the source activities of the right cuneus, right posterior cingulate cortex, right precuneus, left supramarginal gyrus, and left lingual gyrus were significantly lower in the high CTQ group than in the low one (all p < 0.01). There were significant negative correlations between the total CTQ scores and the Nogo P3 amplitudes in the frontocentral (p = 0.03) and parietal regions (p = 0.02), which showed lower source activity in the Nogo P3 condition. @*Conclusion@#Depressed patients with severe childhood trauma showed different Nogo-ERP characteristics, which might reflect inhibitory failure and dysfunction in related brain regions.
