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.

Intermittent excessive behaviors can lead to, or deepen, addiction. The literature does not support claims that the quantity of use of a behavior equals the degree of addiction.

COMMENTS: You can read the lay articles below for a better understanding. As the conclusions say, those who score high on a food addiction test had brain responses to food similar to drug addicts response to drugs. The two similarities were: 1) Excessive activation of the reward circuitry we given cues (pictures of food) 2) […]
