ADHD commonly occurs with a reading disability (RD);
inattention has been linked with poorer reading measures
in ADHD. However, the neural basis of the association
has yet to be investigated. Age interactions and main
effects of diagnosis were modeled for functional
activations in ADHD+RD, ADHD-RD, and controls during a
sustained attention fMRI task. Results suggest that
developmental patterns may be similar in ADHD subgroups
compared to controls, but the degree of hypoactivation
in attention-related areas is significantly worse in
ADHD+RD.
