Game brain

A self-inflicted developmental disabilty of millenials, caused by chronic digital media addiction, and characterized by short attention span, quick frustration, indiscipline, fatigue, and inability to absorb verbal information.

Doctor: I'm diagnosing you with game brain, probably caused by 2,000 hours of World of Warcraft, and exacerbated by 1,000 hours of GTA. I'm writing you a prescription for methadone. With treatment, you may one day be a person again.
