Author and psychologist, Dr. Nicholas Kardaras, Ph.D., explains in his book, Glow Kids: How Screen Addiction Is Hijacking Our Kids - And How To Break The Trance, some of the many neurological, emotional and physical impacts that screen use has on children.
After seeing an increasing number of video-game addicted young people who were experiencing Video Game Induced Psychosis, he began studying the research that has been done into the clinical and neurological impacts of screens on kids.
He outlines what he found in his book. Some of the most disturbing findings show that "video games to the alienated kid and social media for the cheerleader are both just as addicting as heroin is to a junkie." (from Ch. 1, page 14 of Glow Kids)
He also explains in a summary on his website that "Brain imaging research shows that stimulating glowing screens are as dopaminergic – dopamine-activating – to the brain’s pleasure center as sex." and that "Current clinical research correlates screen tech with disorders like ADHD, addiction, anxiety, depression, increased aggression, and even psychosis. Most shocking of all, recent brain imaging studies conclusively show that excessive screen exposure can neurologically damage a young person’s developing brain in the same way that drug addiction can."
