Gray Matter Abnormalities In Internet Addiction: A Voxel-Based Morphometry Study (2009)

COMMENT: Adolescents with internet addiction have decreased gray matter in portions of the frontal cortex. Decreases in size and functioning the frontal cortex are found in all addiction processes. I wonder about the extent of porn use in the Internet addiction group. Another example of a non-drug addiction causing brain changes similar to substance abuse disorders.
