Young adults who watch a lot of television may have cognitive problems later, according to a study published today which were followed 3,000 people for 25 years.
The study found that participants who watched TV more than three hours a day when they were young people are twice as likely to have cognitive problems throughout his adult life than those who are more active and spend less time in front of a screen.
A total of 3,247 adults, aged between 18 and 30 years, were followed during the study, published today in the Journal of the American Medical Association (JAMA) Psychiatry .
The researchers tested their cognitive activities after 25 years through three tests to evaluate their reflexive speed, executive functions and verbal memory.
“The participants habits less active life, ie with little physical activity and too much television, they were more likely to have poor performance on cognitive tests, “says the study.
However, verbal memory was not affected . from an overdose of television

Andrew Przybylski, a psychologist at Oxford University who was not involved in the work, questioned the study: “In First, the data are based on a measurement made by the participants of the time they spend watching television, this can be problematic. “
On the other hand, those involved did not perform cognitive tests at baseline study, which would have baseline data. Also, “almost one in three did not attend the end of the study,” which weakens the conclusions of the work, regretted Przybylski. (AFP)
