“…Furthermore, an increasing number of studies report chemical and behavioral addictions share similar course, history, and neurobiological correlates (Grant, Potenza, Weinstein, & Gorelick, 2010;Griffi ths, 2005;Orford, 2001). In relation to the similarity in history of drug and behavioral addictions, Carroll and Robinson (2000) found that undergraduate students who were children of alcoholics or workaholics were more likely to adopt such behaviors from their parents earlier in their lives compared to the other students, and they reported their parents' workaholism or alcoholism as the reason for them to do so. Perhaps the most compelling evidence comes from neurological studies, as these support the hypothesis that (a) reward circuits in the brain are involved in substanceand non-substance-based addictions, (b) both share similar genetic vulnerability and clinical features, and (c) that they develop following a similar pattern (i.e., initial arousal before the act, pleasure/high relief linked to the act, and lowered arousal afterward with guilt, withdrawal, and potential tolerance) (Grant et al, 2010;Villella et al, 2011).…”
