Shared grey matter correlates of reading and attention

•Reading and attention difficulties occur together more often than chance.•The neural bases of this comorbidity are not well understood.•We investigated shared neural correlates of reading and attention in healthy youth.•Grey matter correlates overlapped in the precuneus and caudate nucleus.•These are potential regions of interest for comorbid reading and attention problems. Disorders of reading (developmental dyslexia) and attention (ADHD) have a high rate of comorbidity (25–40%), yet little is known about the neural underpinnings of this phenomenon. The current study investigated the shared and unique neural correlates of reading and attention in 330 typically developing children ages 8–18 from the Philadelphia Neurodevelopmental Cohort. Multiple regression analyses were used to identify regions of the brain where grey matter (GM) volume was associated with reading or attention scores (p
