According to the Daily Mail, doctors can quickly diagnose children with ADHD through a simple brain scan.
This breakthrough is due to the scientists' new findings, and the researchers found that children with ADHD had a relatively slow brain development compared with other children of the same age.
The cluster of pathways in the brain develops into a network of brains as the brain develops. Different pathways control different neurophysiological processes, such as analyzing images and accessing memory.
Different brain networks are interconnected to perform specific functions. For example, when we look at a photo, one pathway in our brain processes color and shape, and the other pathway awakens the memory associated with it.
The researchers found that children with ADHD have a lower level of maturity in their brains that control internal thoughts such as daydreaming, while the brain network allows us to concentrate on tasks.
Delays can explain why children with ADHD are more likely to be bothered and unable to concentrate.
At the same time, the new findings allow doctors to use brain scans to diagnose ADHD and monitor how patients respond to treatment.
At present, the diagnosis of ADHD is to conduct a formal assessment of the child to a paediatric or psychologist by communicating the symptoms with the parents of the child. The assessment is based on discussion and observation of child symptoms.
The study used computer technology to analyze published brain scan data pools. The research team included 275 children and adolescents with ADHD and 48 unaffected children.
They use the "connectomic" method to draw connections between brain networks.
The researchers found that ADHD children's internal attention network (basic model network) development and connectivity development, as well as the external attention network (active task network) development is relatively slow.
The findings also help researchers understand the developmental process of ADHD from childhood to adulthood. Some children will recover automatically, and some children will still have ADHD in adulthood. Dr. Chandra Sripada of the Department of Psychiatry at the Michigan Medical School said that studying the brain maturity of children with ADHD will find reasons to explain this phenomenon.
The PhD also said that the "connectomic" approach can also be used to study other diseases caused by differences in brain connections, such as self-disorders and schizophrenia.
