Children's brain changes with too much use of screens



The first results show significant differences in the middle of children who use phones, tabldi and video games more than seven hours a day.

They can be entertaining and help parents keep silent, but a study has hidden light on how harmful screens can be for children. According to the research, the brain of children who spend too much time in front of smart devices or video games seems to change.

The study was carried out by the United States National Health Organization, through 21 research centers, where 4,500 children aged 9 and 10 were examined to know if the intensive use of video and time games they spent Internet influences its development.

The first results of this study with magnetic resonance imaging (MRI) show significant differences in the middle of children who use smart phones, tablets and video games more than seven hours a day, researcher explained Gaya Dowling.

The primitive thinning images of the cortex or cortex cortex, which processed the information sent to the brain, showed the five senses. Tanhau & cortex "It's considered an aging process", said the scientist told the CBS network.

Kara Bagot, one of the researchers, said smartphones can have adverse effect because the time spent in front of a screen stimulates the release of dopamine, the enjoyable hormone. The NIH data showed that children who spent more than two hours a day on screens resulted in poorer consequences in language tests and reasoning. However, the final results will be published in 2019.
