Previous studies have often looked at whether children with attention-deficit hyperactivity disorder (ADHD) have differences in certain areas of the brain. A new study aims to question this method using a global approach. It opens the way for potential improvement of diagnostic tools for this neurodevelopmental disorder.
Attention-deficit hyperactivity disorder (ADHD) is a common neurodevelopmental disorder characterized by cognitive, behavioral, and emotional differences. The structure and functioning of the brains of people with it differs from the rest of the population.
The brain as a whole
A new study published in Journal of Neuroscience Put it in a lighta light The complex relationship between brain connectivity and hyperactive behavior disorders. The US researchers used a large national data set (on nearly 12,000 children) and neuroimaging to ascertain the cumulative effects of ADHD on the entire brain, rather than looking only at specific areas.
Concretely, researchers usedProfessional in magnetic photogrammetryProfessional in magnetic photogrammetry At rest in order to visualize the general brain activity of children. It also allowed them to identify brain connectivity patterns specific to ADHD using the Polyneuropathy Risk Score (or PNRS), a method that calculates the likelihood of a health outcome based on a patient's brain activity.
Facilitating the diagnosis of children
The study's comprehensive approach emphasizes that ADHD involves multiple areas of the brain that interact in complex ways. ” By assessing the cumulative effects of regions across the brain, we now view ADHD as a whole-brain problem, which may make it easier to predict which children have ADHD and how much. gravitygravity from this disorder, He made it clear Michael A. Mooney, author of the study. Ultimately, we hope this will contribute to the early identification of children most at risk, so they can get the help they need as soon as possible. »
