Internet addiction is defined by Dr. Weinstein and Dr .Lejoyeux as excessive or poorly controlled preoccupations, urges, or behavior regarding the internet use that leads to impairment or distress. There are at least three subtypes of internet addiction: gaming, cybersex, and email or text messaging. Internet addiction and all three of its subtypes have the features of withdrawal, tolerance, and negative repercussions. Withdrawal systems that are associated with internet addiction are sweating, nausea, anger, and irritability. People with internet addiction will show signs of tolerance by justifying the purchase of the latest and greatest computer equipment or finding more time to spend on the internet. Some of the negative repercussions may be social isolation, poor performance at work or at school, inability to keep appointments, and fatigue.
There are three different proposed models for classifying internet addiction. Those who think that internet addiction should be included as a separate disorder believe that it should be listed as a separate disorder under the non specified impulse-control disorder. Some researchers believe that internet addiction should not be listed as a separate disorder and that it is an impulse-control disorder that is on the obsessive-compulsive spectrum. Brain imaging and pharmacological treatment studies support this argument. The third proposed model would be that internet addiction is a behavioral addiction. Psychiatrists believe that it is part of a behavioral addiction because of the adverse consequences, withdrawal, and tolerance that are typical attributes of a behavioral addiction.
I think it will be interesting when more information and studies are done on internet addiction. From the information that I have read, internet addiction is a lot like a drug addiction. I thought it was very strange that people who have an internet addiction suffer from withdrawal symptoms like nausea, sweating, and anger. Before my research on the topic, I assumed that internet addiction was just caused by a misuse of time. I thought that it would only cause social problems and issues with school and work. I did not realize that some suffer physical symptoms from internet addiction.
