Executive functioning deficits persist well into adulthood for individuals with ADHD, according to a new study1 in the Journal of Attention Disorders that affirms the clinical theory that executive dysfunction is a core symptom of attention deficit hyperactivity disorder.
The small Norwegian study looked at attentional processing capacities — namely pre-attentive and executive functioning — in a group of people with and without ADHD over a 23- to 25-year period. Pre-attentive processing — the basic, preliminary stage in the brain whereby auditive and visual stimuli is analyzed — is not as well understood in relation to ADHD as is executive functioning — the controlled brain processes (like working memory) that allow us to integrate information and select optimal actions — the researchers said.
These two processes, according to the researchers, exist on “contrasting ends of [the] ‘attentional processing continuum.’” Because pre-attentive processing deficits may be precursors for brain function deficits of a higher order (like executive functioning), the study aimed to “gain insight into the long-term changes in attentional capacity” for “a clearer conception of attention dysfunction in ADHD.” Click here to read the rest of the story.
