Attention-deficit/hyperactivity disorder (ADHD) has a
high prevalence but the neurobiological mechanisms
underlying ADHD remain unclear. We characterize resting
EEG-fMRI coupling differences between ADHD and controls
by EEG-fMRI. Based on the literature, we expected
EEG-fMRI alterations in central resting and cognitive
control networks. In 33 adults (17 ADHD), frequency-band
specific EEG power was correlated with fMRI signal
alterations during alternating eyes open and closed
blocks (p < 0.05 corrected). We found bidirectional
group differences in low (theta) to high (alpha)
frequency bands in regions of the described networks. We
conclude that sensory- and cognitive processing is
compromised in adults with ADHD.
