0.400 GeneticVariation disease BEFREE <b>Introduction:</b> Studies have documented both executive functions (EF) impairment in children with Attention Deficit / Hyperactivity Disorders (ADHD) and Theory of Mind (ToM), yielding mixed results, possibly because of a variety of tasks used, all requiring different levels of language skills.<b>Aim:</b> To investigate the relationship between ToM and EF with non-language-based tasks.<b>Methods:</b> Thirty ADHD (7-9 years old) were compared to thirty controls (age and IQ matched). 31661370 2020
