Association between auditory mismatch negativity and visual working memory in school-age children with ADHD

This study examined 86 children with ADHD and 90 typically developing children using EEG to measure auditory processing (mismatch negativity) during an oddball task and assessed visual working memory capacity. Children with ADHD showed reduced auditory mismatch negativity amplitude and poorer visual working memory compared to controls, with an unexpected inverse relationship between MMN amplitude and cognitive impairment severity that suggests shared neurobiological mechanisms underlying auditory and visual cognitive processing.
