Background:Problems with emotional processing are widely reported in individuals with attentiondeficit/hyperactivity disorder(ADHD).Although methylphenidate(MPH)effectively alleviates inattention and hyperactivity symptoms in ADHD,its effects on emotional processing and internalizing symptoms have remained *** we previously found that acute MPH administration modulated neural mechanisms underlying emotional processing in an age-dependent manner,the effects of prolonged administration remained ***:Therefore,we investigated:(i)whether prolonged MPH treatment influences neural substrates(amygdala reactivity and connectivity)of emotional processing,and(ii)whether these effects are modulated by ***:The“effects of Psychotropic drugs On Developing brain-MPH”(“ePOD-MPH”)randomized controlled trial was a 16-week double-blind,placebo-controlled,multi-center trial with MPH in 50 boys(10–12 years of age)and 49 men(23–40 years of age),all stimulant treatment-naive and diagnosed with *** performed an emotional face-matching task during functional magnetic resonance *** assessed their symptoms of ADHD and internalizing symptoms at baseline,during the trial(8 weeks),and 1 week after the trial end(17 weeks).Results and Conclusions:We did not find effects of prolonged MPH treatment on emotional processing,as measured by amygdala reactivity and connectivity and internalizing symptoms in this trial with stimulant treatment-naive *** differs from our findings on emotional processing following acute MPH administration and the effects of prolonged MPH treatment on the dopamine system,which were both modulated by ***,prolonged MPH treatment did improve ADHD symptoms,although depressive and anxiety symptoms showed a medication-independent ***,our data indicate that baseline internalizing symptoms may be used to predict MPH treatment effects on ADHD symptoms,particularly in(male)adults with ADH
