A new study has revealed distinctive brain functions in children with Attention-Deficit Hyperactivity Disorder (ADHD). The National Institutes of Health study showed that children with ADHD had more wirings in their brains compared to children without the disorder. This abnormality makes it challenging for their brains to send clear signals during tasks.
This groundbreaking research explains the inordinate brain connectivity linked to ADHD symptoms. Essentially, the excessively connected brain wirings could hinder signal transmission in children with ADHD.
In the past, ADHD studies had less satisfactory samples, often less than 100 participants, and failed to identify the brain areas affected by ADHD. In contrast, this recent study used thousands of brain scans from six different data sets, offering a detailed understanding of how the ADHD brain operates, even when at rest.
The autonomous study by Lauren Friedman, Arizona State University Assistant Psychology Professor, affirmed that this study didn’t ascertain how ADHD is diagnosed but rather unearthed specific brain signals that are indicative of ADHD.
The study covered over 8,000 children; about 1,700 had diagnosed ADHD. Among them, the frontal cortex (controlling attention) had increased wirings to the deeper brain structures. This elaborate wiring led to altered connectivity, according to the study.
More research is awaited on ADHD children’s brain activities and growth patterns. Meanwhile, experts consider this study a milestone, shedding light on the peculiar brain operations in ADHD children.
