简要总结
To determine whether methylphenidate has a different impact on the brain circuits associated with cognitive functions in the two clinical populations studied (adult ADHD patients and patients with attention deficit post-mood disorder) and compared to controls.

- •Group B: patients with attention deficit due to/accentuated by mood disorders (ADHD-HD) - Association of ADHD symptoms with attentional disorders according to the combination of the following criteria: * DSM-5 diagnosis of recurrent depressive disorder or bipolar disorder *Currently euthymic, i.e., a QIDS-16 depression score < 6 (Appendix 1) and a YRMS mania score < 6 (Appendix 2), and clinically stabilized for at least 6 weeks prior to inclusion (stable treatment and out of acute phase). NB: for QIDS item 10 (concentration/decision making, score only decision making) *Criterion A of adult ADHD according to DSM-5 (at least 5 symptoms of inattention and/or hyperactivity/impulsivity) *Absence of Criterion D in childhood, adolescence and prior to mood disorders (i.e., absence of significant impact with reduced social, academic or occupational functioning) *Criterion D present (symptoms have a significant impact with reduced social, academic or occupational functioning) - Whether or not the subject is receiving treatment for mood disorders that is approved for: *mood stabilizers (lithium, valproate, lamotrigine, oxcarbazepine), *antidepressants (SSRIs, SNRIs ≤150mg/d venlafaxine and ≤60mg/d duloxetine), benzodiazepines at stable doses for more than one month (maximum daily dose of 10mg diazepam equivalent). - Subjects with or without methylphenidate treatment
- •Group C: healthy control subjects - Subjects with no psychiatric or neurological history

Effect of methylphenidate on the task vs. rest in a region defined by its involvement in the cognitive task and its reactivity to methylphenidate. ROI (Region of Interest) analysis to maximize power.
次要结局
- Decrease in rCBF (regional Cerebral Blood Flow) in the methylphenidate condition vs. placebo, in the different groups.
- Improved cognitive performance on tests of sustained attention, working memory and flexibility following the administration of methylphenidate, in the different groups.
- Stabilization of the power of the EEG spectrum in the low frequencies (delta (1-4Hz) and theta (4-8Hz)) in the methylphenidate condition vs. placebo.
- MRI: Interaction group x treatment x task on cerebral activation linked to sustained attention and linked to the inhibition corresponding to each of these tasks.
- EEG: Group x treatment x task interaction on the amplitude of the XML File Identifier: 0Vmd7NrSRK8JeP+9ISLPaO9Oq+U= Page 14/26 P300 wave linked to sustained attention (P300b) and linked to inhibition (P300a) corresponding to each of these tasks.
