translated from Spanish: Exposure to screens could affect the brain of children

the initial results of a study funded by the National Institute of health (NHI for its acronym in English) from the United States suggest that prolonged exposure to the pa ntallas can negatively affect development of the brain by reducing the cerebral cortex, which processes sensory information. After analyzing of 4500 children brain scans, the researchers found that those who had spent more than seven hours exposed to cell phones, PCs or video game suffering from a premature reduction in the region of the brain responsible for of the interpretation of the information in the real world. Gaya Dowling, the leader of the investigation, was cautious regarding the conclusions that you can obtain from these initial analysis although the difference of development has been significant (a 37 per cent lower) for those with less time use. “We don’t know if it is caused by the time of exposure to the screens,” said in an interview with the program 60 Minutes. “We do not know if something bad.” We won’t know it until they can study them for a while to see if there are results associated with the differences present in this single image.” However, Dowling said that interviews and information from the NIH revealed that children who confirmed to use screens for more than two hours a day obtained lower scores on logic tests and language. 
“We don’t know if it is caused by the time of exposure to the screens,” said the leader of the Gaya Dowling Studio.

The study, called development cognitive brain adolescent (ABCD for its acronym in English), will analyze the development of over eleven thousand children of nine and ten years of age a decade in 21 centres of research. The aim is to improve the understanding of the environmental, social, genetic and biological factors that can affect the brain and cognitive development. Research published in July this year on the portal of medicine JAMA linked the frequent use of technology (particularly social networks) hyperactivity disorder attention deficit after following the development in adolescents of 15 and 16 years for a period of 24 months. Specialists recommend that children under two years old do not have exposure to screens of any kind, and that will limit children from six years to one hour per day to not affect the cycles of sleep, or physical activity. The goals seem unrealistic, according to a survey of the Iberoamericanos.De States Organization agreement between the parents consulted for study of the institution, 75 per cent of children aged zero to five years used digital technologies all the days and 58 per cent of the children aged between zero and two years makes it daily.
