    Study Notes

    Neuroscience of Internet Pornography Addiction

    • Many behaviors can lead to loss of control and addiction-like symptoms, affecting reward circuitry similar to substance abuse.
    • Neuroscience research suggests that internet addiction, including internet pornography use, has similar neural processes to substance use addiction.
    • The APA recognized internet gaming disorder as a potentially addictive behavior in 2013. Other internet behaviors, like internet pornography use, were not specifically addressed.
    • This review aims to address the neuroscience of internet pornography addiction (IPA) and connect the findings to existing addiction models.

    Introduction

    • Addiction is now understood as a chronic disease of the brain affecting reward, motivation, memory circuitry, and related social/spiritual elements.
    • The ASAM (American Society of Addiction Medicine) expanded addiction's definition in 2011 to include behaviors and substances.
    • The DSM-5 acknowledges behavioral addiction, including gambling disorder. There is now growing neuroscientific support for recognizing behavioral addictions, including Internet use, comparable to substance use disorders.
    • The APA's recognition of IGD (Internet Gaming Disorder) led to a focus on subtypes of internet addiction, but other excessive internet use (e.g., social media, pornography) hasn't been extensively reviewed, unlike Internet gaming.

    Methods

    • A comprehensive literature review used various databases and criteria.
    • Studies focused on neurobiology of addiction, addiction in general, gambling disorder, internet addiction, and, in particular, internet pornography addiction.
    • Relevant studies were published in peer-reviewed journals within a specified time period.

    Neurobiology of Addiction

    • The mesolimbic dopamine pathway, crucial to reward processing, is affected by addictive substances and behaviors. This system's engagement by internet use (especially internet pornography) is discussed
    • Addiction progresses through sequential stages: binge/intoxication, withdrawal, and preoccupation/anticipation.
    • Repeated addictive behaviors can cause lasting changes in the brain's reward system, resulting in excessive wanting, loss of control, and compulsive behavior.
    • The anti-reward system, working in conjunction with the reward system, mitigates addictive behaviors.
    • Learning and habit development are central to addiction, involving classical and instrumental conditioning.

    Neurobiology of Internet Addiction (specifically Internet Pornography Addiction)

    • Studies link internet pornography addiction to neurobiological processes similar to substance use disorders.
    • Brain imaging studies show overlapping neural activity in areas associated with reward and craving in both substance and behavioral addiction.
    • Some studies show blunted responses to non-addictive stimuli in internet addicts, mirroring tolerance effects observed in substance addiction.
    • Studies suggest that frequent internet pornography use may result in desensitization to sexual stimuli, similar to tolerance in substance use, leading to a need for more intense stimulation to achieve the same effect.
    • Neuropsychological tests show impairments in executive functioning (e.g., attention, working memory) in internet pornography users, potentially due to increased wanting for pornography.
    • Genetic components may also play a role in vulnerability to Internet pornography addiction.

    Conclusions

    • The reviewed studies highlight neural parallels between internet-related behaviors and substance use disorders, supporting a view that internet pornography addiction fits into a broader framework of addiction.
    • A comprehensive understanding of internet pornography addiction needs to account for both the neurobiological and behavioral aspects, acknowledging similarities to substance use disorders.
    • Further research is needed to solidify a better understanding of IPA, including clinical trials and longitudinal studies.
