A surprising 16 percent of 18- to 25-year-olds might suffer from Internet addiction, according to a survey conducted by the Digital Clarity marketing agency. Most of the 16 percent suffering addiction-related problems spend at least 15 hours per day using the Internet.
The Digital Clarity survey took a look at the following characteristics: how many hours were spent online, whether or not they became irritable if they weren't using the Internet, if they felt guilty spending so much time online, possible isolation due to online activity, and noting a sense of euphoria if using the Internet.
Researchers are most interested to see if dopamine in the brain is released the same way for Internet addicts as alcoholics or drug addicts. However, critics of trying to label Internet addiction believe the problem could be related to other psychological issues - and is becoming a more talked about debate in the mental health community.
A Google Glass wearer was recently treated for Internet addiction, with the patient stating notable irritability when unable to use Glass.
