Standing long before the screen can change the brain shape of children

Scientists conducted scans in the brains of children between three and five years of age, and compared the results with the use of the screen. Those who spent most of their time in tablets, telephones, and TV had fewer white substances in their brain, showed the results.

The white matter helps to send messages from one area to another through ethnicities. The affected traitors included those who support language skills, such as speech, thinking, and reading.

The same children also scored fewer successes in literacy tests, according to the results of the study of the Children's Hospital Medical Centre Cincinnati.

But critics of research implied that the findings are not true and urged parents not to worry if their child's brain was damaged.

The study, published in the American Medical Association's Journal of Pediatrics, included 47 healthy children 27 girls and 20 boys.

Leading author John Hutton and colleagues urged their parents to report how many children used screens using the ScreenQ test, a questionnaire of 15 articles taking into account the easy approach, frequency of use and viewing content.

There are no official guidelines for the screen deadlines. But there are calls for interventions that need to be carried out because of growing concern about the impact of the time before the screen and the use of social media, on mental health and youth well-being.

The Royal College of Patients and Health (RCPCH) and the American Association of Pediatrics (AAP) give instructions for parents. Among the AAP guidelines used as a reference to the study are:

- For children less than 18 months, avoid using the media on screen except for video talk.

-The parents of children between the ages of 18 and 24 months who want to convey digital media must choose a high-quality programming and watch it with their children to help them understand what they're seeing.

For children between the ages of 2 and 5, limit the use of the screen to 1 hour a day of high quality programs.

-Parents need to co-view the media with the kids to help them understand what they're seeing and implement it in the world around them.

-Cite media-free time together, such as dinner or driving, as well as media-free locations at home, such as bedrooms.

AAP advises children between three and five years of age to spend no more than an hour a day in front of the screen.

At the same time, children were subjected to the MRI scan and participated in three standard tests measuring language, including their vocabulary, reading and speed of access to information.

Young people with a high sreenQ score had the lowest quality of white brain matter, which affects the formation of myelin a fatty substance covering the nerve fibers of white matter in the brain.

It allows nerve impulses to move quickly to ʹtrakte, which send messages between different parts of the brain. If myelin is spent normally because of the disease, messages can't be passed that fast.

The practices involved in the brain of children included the executive function, which is involved in self - control.

Hutton and colleagues did not specify how many screen hours a day were related to changes.

The test's connoisseur results seemed to support the findings: High-users also performed weaker in cognitive tests.

Professor Derek Hill of University College in London said the results are preliminary and that this is a small study since it does not include children from around the world.

Otherwise, last year another U.S. study found that children who spent the largest time on screens had about five percent lower cognitive function than children between eight and 11 years of age.

More than half of children between three and four years of age in Great Britain use the Internet every week, and one in five has their tablet.
