Molecular and Functional Imaging of Internet Addiction
With the introduction of new technologies, computer and internet use have become an unavoidable necessity in our daily lives. Internet was originally designed to facilitate communication and research. However the dramatic increase in use of internet in recent years has led to its pathologic use. In the past decade, research has incerased suggesting that excessive Internet use can lead to the development of a behavioral addiction. Internet addiction (IA) has been considered as a serious threat to mental health and the excessive use of the Internet has been linked to a variety of negative psychosocial consequences . Although in DSM-V, there is not a category such as internet addiction, internet gaming addcition has been included in the appendix of the DSM-V, with a goal of encouraging . Recently, there has been increasing interest in investigating the neurobiological mechanisms of IA using neuroimaging. Neuroimaging studies offer an advantage because with this method, it is possible to distinguish particular brain areas that are involved in the development of addiction. Understanding the neural basis of poor impulse control in IA is important for understanding the neurobiological mechanisms of this syndrome, because IA is growing both in prevalence and within the public consciousness as a potentially problematic disorder.
