Internet addiction is real, researchers out of the University of Bonn say, and its source can be explained at the molecular level.
Researchers from the school's departments of psychology and neuroscience report in the September 2012 issue of the Journal of Addiction Medicine that a simple variation on the CHRNA4 gene results in a significantly higher prevalence of Internet addiction -- and particularly in women.
"Internet addiction is not a figment of our imagination," lead author Christian Montag says in a news release. "The current data already shows that there are clear indications for genetic causes of Internet addiction... If such connections are better understood, this will also result in important indications for better therapies."
