There are different variations in brain activity in children with and without ADHD. This conclusion was made by scientists from the University of North Carolina.
Researchers from the USA decided to map the brain activity and the so-called cognitive flexibility of children with and without attention deficit hyperactivity disorder. During the study, variations in the brain activity of children from two different groups were recorded. The findings could help clinicians better identify young patients with ADHD and track the severity of their condition as well as the effectiveness of therapy.
Children who are overly active have slower brain development
Some people have greater cognitive flexibility. This is not just luck in terms of heredity, we can improve this indicator as soon as we really do it. Here is an example of cognitive flexibility – when we sit down to dinner, we leave the table to chop onions, then send a text message to a friend, return to the table, not forgetting the need to bring chopped onions. Then we finish dinner, maintaining a dialogue with our spouse.
Scientists have discovered which children have smaller brains
We all demonstrate cognitive flexibility as we communicate in different styles with a friend, child or work colleague, or solve some problem that requires creativity. This is part of our executive functions of the brain. However, these functions are very poorly developed in children with ADHD, and this persists into adulthood. In the absence of cognitive flexibility, we cannot focus on performing any tasks. This problem complicates the process of obtaining new knowledge and performing certain tasks. (READ NEXT)
