ADHD Study Challenges Basic Assumption About Attention
New research involving 7,000 children suggests that ADHD-related brain connectivity operates distinctly from networks tied to basic attention skills.
Research from the Alberta Children’s Hospital Research Institute at the University of Calgary is challenging long-held assumptions about ADHD and its relationship with brain connectivity related to attention. The study, analyzing data from over 7,000 children aged nine and ten, indicates that the brain connectivity associated with ADHD is distinct from the networks governing basic attention skills.
Previous theories posited that individuals with ADHD might have physical differences in the connections between brain regions responsible for inhibitory control and attention. This extensive study utilized data from the Adolescent Brain Cognitive Development database, including resting-state fMRI scans, for nearly 500 children diagnosed with ADHD and a control group.
The research identified independent patterns linking resting brain connectivity to both attention scores and ADHD diagnosis status. This suggests that the networks involved in basic attention function separately from those specifically linked to ADHD.
Researchers noted that the study focused solely on nine and ten-year-old children and employed a single measure for inhibitory control. They recommend future projects incorporate multiple assessment methods for a more comprehensive understanding of childhood cognitive function.
