Summary

In the past few decades, the notion of what constitutes addictive behavior has expanded to include nonsubstance-related behaviors. The World Health Organization recently recognized gambling and gaming disorders as addictive behaviors, and there has been support in the field to include compulsive sexual behaviors as well. Considerable support for reclassification of these behaviors from impulse-control disorders to addictive behaviors has come from studies showing neurobiological similarities with substance use disorders. Behavioral addictions have been found to have similar neurobiological correlates with each other and with substance use disorders on multiple levels of analysis such as alterations in availability of receptors in mesolimbic pathways, the amplitudes of cue-induced late potentials, and frontostriatal activity during reward-based tasks. The implicated neuropathological features support the inclusion of nonsubstance behaviors as addictive behaviors.
