Is there such an addiction known as Video Game Addiction. My nephew was top 50 in his class. He is now belligerent, ambivalent and lethargic He is very nasty to my sister, sits in his room at University of Delaware and did not complete an incomplete. He lost his scholarship. I was speaking to a friend who told me that her friend is experiencing the same thing with her son and it was diagnosed video game addiction. Thank you.
