Differential effect of reading training on functional connectivity in children with reading difficulties with and without ADHD comorbidity

Publication date: February 2019Source: Journal of Neurolinguistics, Volume 49Author(s): Tzipi Horowitz-Kraus, Alexander Hershey, Benjamin Kay, Mark DiFrancescoAbstractA comorbidity of attention deficit hyperactivity disorder (ADHD) with reading difficulties (RD) is common in children. However, children with ADHD + RD have a different reading and executive functions (EF) profile than children with RD alone. We compared the effect of an EF-based intervention on neural circuits related to EF in children with RD and those with ADHD + RD. Functional connectivity MRI data from a lexical decision task suggest that the RD-alone group showed greater improvement in EF and reading tests and greater functional connectivity between networks related to both higher- and lower-level visual processing ...
