What drives the brain's transcriptional response to addiction?

Research in animal models demonstrates that compulsive behaviors, such as sexual addiction, arise from the same underlying transcriptional and epigenetic mechanisms that mediate drug addiction. A central molecular player in both substance and behavioral addictions is the gene transcription factor Delta-FosB. These shared neural adaptations suggest that behavioral and drug addictions rely on identical biological processes within the brain's reward system.

What we know

• Animal research establishes that compulsive sexual behavior arises from the same transcriptional and epigenetic mechanisms that mediate drug addiction. [2]
• A gene transcription factor known as Delta-FosB is identified as a necessary common factor involved in both behavioral and drug addictions. [4]
• Behavioral addictions and drug addictions are associated with the same set of neural adaptations driven by the brain's reward system. [4]

Still open

• There is ongoing debate among specialists regarding whether compulsive sexual behavior or other non-substance activities should be formally classified as clinical addictions.
