A link between the Internet addiction and nervous breakdowns

According to a study published in 2010 in the american magazine "Pediatric and Adolescent Medecine", and supervised by Lawrence Lam (from the Sydney Medecine School) and Zi Weng-Peng (from the chinese Ministry of Education), teenagers who are addicted to the Internet are more likely to get a nervous breakdown then others.
More than 1 000 chinese teenagers (from the area of Guangzhou) have been asked about their use of the Internet. A huge majority are considered as normal Internet users. Only 6,2 percent have been identified as Internet addicts and the psychological evaluation shows that these teenagers could more easily have a nervous breakdown then others teenagers.
