To investigate whether or not the deficits in executive functions in the attention deficit hyperactivity disorder (ADHD)affect reading comprehension and identify a potential biological marker of this neuropsychological endophenotype throughevent-related potentials (ERP). The phenotypic association between reading comprehension and the specific functions ofinhibition and working memory is studied.Subjects and methods. The sample consisted of 52 children with ADHD (8-13 years) divided in two groups according to thepresence (TDAH–; n = 27; percentile < 30) or the absence (TDAH+; n = 25; percentile > 50) of reading comprehensiondeficits and a control group (n = 27). The executive functions were evaluated. The ERPs were assessed during a task inwhich anaphoric sentences of different lengths were presented, recording the ERP in the last adjective of the sentencethat required a gender agreement.Results. Working memory and inhibition were associated to reading comprehension performance. The ADHD+ group andthe control group seem to detect the disagreement at 100 ms, while the ADHD– group does not activate its workingmemory until 250 ms.Conclusions.
