Los posibles efectos nocivos del tiempo prolongado frente a la pantalla y del empleo de la tecnología incluyen síntomas como marcado déficit de atención, deterioro de la inteligencia emocional y social, adicción a la tecnología, aislamiento social, deterioro del desarrollo cerebral y alteraciones del sueño.
La evidencia científica que está surgiendo muestra que el empleo frecuente de la tecnología digital tiene un impacto significativo, tanto negativo como positivo, en la función cerebral y en el comportamiento. Additional research on the positiveĪnd negative brain health effects of technology is needed to elucidate mechanisms and Interventions that may improve mood and behavior. Health interventions providing self-management, monitoring, skills training, and other Intelligence, and other cognitive abilities. Significant increases in brain neural activity during simulated internet searches.Ĭertain computer programs and videogames may improve memory, multitasking skills, fluid Imaging scans show that internet-naive older adults who learn to search online show Various apps, videogames, and other online tools may benefit brain health. Harmful effects of extensive screen time and technology use include heightenedĪttention-deficit symptoms, impaired emotional and social intelligence, technologyĪddiction, social isolation, impaired brain development, and disrupted sleep. Significant impact-both negative and positive-on brain function and behavior. The N.F.L.’s top health and safety official has acknowledged a link between football and C.T.E., and the league has begun to steer children away from playing the sport in its regular form, encouraging safer tackling methods and promoting flag football.Emerging scientific evidence indicates that frequent digital technology use has a prevalence would be close to 9 percent, vastly higher than in the general population. So even if every one of the other 1,200 players had tested negative - which even the heartiest skeptics would agree could not possibly be the case - the minimum C.T.E. About 1,300 former players have died since the B.U. player’s risk of developing C.T.E., which can be diagnosed only after death. “There’s a tremendous selection bias,” she has cautioned, noting that many families have donated brains specifically because the former player showed symptoms of C.T.E.īut 110 positives remain significant scientific evidence of an N.F.L. McKee is far from a random sample of N.F.L. The set of players posthumously tested by Dr. But the brains of some other players found to have the disease - like Junior Seau, Mike Webster and Andre Waters - were examined elsewhere. McKee, chief of neuropathology at the VA Boston Healthcare System and director of the CTE Center at Boston University, has amassed the largest C.T.E. He died in 2011 at age 80 after being mostly bedridden with dementia, his nephew told The Associated Press, adding that Matson hadn’t spoken in four years.ĭr.
