Internet addiction disorder may be associated with abnormal white matter structure in the brain, as reported in the Jan. 11 issue of the online journal PLoS ONE. These structural features may be linked to behavioral impairments, and may also provide a method to study and treat the disorder.
Previous studies of internet addiction disorder (IAD), which is characterized by an individual's inability to control his or her Internet use, have mostly focused on psychological questionnaires. The current study, on the other hand, uses an MRI technique to investigate specific features of the brain in 18 adolescents suffering from IAD.
The researchers, led by Hao Lei of the Chinese Academy of Sciences in Wuhan, found that IAD is characterized by impairment of white matter fibers connecting brain regions involved in emotional generation and processing, executive attention, decision making, and cognitive control, and suggest that IAD may share psychological and neural mechanisms with other types of impulse control disorders and substance addiction.
As a heavy internet user I suddenly want to know: is my brain white matter tweaked?
Significantly negative correlations were found between FA values in the left genu of the corpus callosum and the Screen for Child Anxiety Related Emotional Disorders, and between FA values in the left external capsule and the Young's Internet addiction scale.
If you have to feel anxiety to have this abnormality then I'm okay. Anxiety is an emotional that I don't much feel. Okay, do I have, like, anxiety deficit syndrome? Its always something.
