Sex Addiction Research Information
A recently released study on pornography and the brain, led by Dr Valerie Voon, University of Cambridge (UK), confirmed sexual addiction as an identifiable and diagnosable disorder of the brain, and affecting three significant brain regions; the dorsal anterior cingulate (anticipating rewards), the ventral striatum (processing rewards), and the amygdala (processing the significance of emotions and events). The Cambridge study on pornography addiction found that these three brain regions mirror the neuronal excitation as seen in drug addiction.
Your Brain On Porn. A study by researchers at the German Max Planck Institute and published in May 2014 in JAMA Psychiatry, found several brain changes associated with the amount of pornography consumed. The study found that higher hours per week, and more years of viewing porn, correlated with a reduction in grey matter (brain cells) in sections of the reward circuitry (the striatum). This region of the brain is involved with motivation and decision making. Reduced grey matter in the reward related region means fewer nerve connections. Researchers interpreted the reduction in nerve connections as a result of longer-term pornography consumption.
This is in line with the hypothesis, that intense exposure to pornographic stimuli results in a down-regulation of the natural neuronal response to sexual stimuli. That could explain why porn addicts are at risk to lose sexual interest in their partners, and why male porn addicts may develop pornography induced erectile dysfunction (PIED).
Researchers confirm that "dysfunction of the reward circuitry of the brain is linked to inappropriate behavioural choices, such as compulsive drug/alcohol/gambling/porn/sex seeking, regardless of the potential negative consequences." In short, there is evidence of an association between porn consumption and impaired impulse control.
A United States conducted study has revealed that 66% of men, and 41% of women consume pornography on a monthly basis. The US data assume that 50% of all Internet traffic is related to sex. Pornography is no longer an issue for a minority population, but a mass phenomenon.
A new definition of sex addiction was first published August 15th, 2011 by the American Society of Addiction Medicine (ASAM), stating that 'addiction is a primary chronic disease of brain reward, motivation, memory and related circuitry, and not simply a behavioural problem involving too much alcohol, drugs, gambling, and sex. The addicted individual pathologically pursues reward and/or relief by sexual or substance behaviour, and other behaviours'.
Addiction is characterised by inability to control such behaviours, inability to persistently abstain, cravings and relapse, dysfunctional emotional response, diminished interpersonal relationship ability, and diminished ability to recognise the significance of their problem.
These findings are a significant step forward of global acceptance that sexual addiction is a brain disorder, and therefore a proof that sex addiction exists, and that it is not simply a bad behaviour. Sex Addiction Australia believes that these studies add a new dimension to the understanding of sexual and pornography addiction, and new opportunities for treatment and prevention.
Acting out compulsive sex is not primarily about feeling more, but about feeling less in order to cope with conscious or unconscious underlying emotional trauma and distress. During sexual preoccupation and activity, various neurotransmitters including dopamine, noradrenaline, endorphins, oxytocin, and serotonin are secreted in larger quantities, and generate instant feelings of relief, relaxation, and elation.
Continued dopamine over stimulation in the reward-learning (dopamine) system, located in the mid brain, eventually interrupts the dopamine pathways to the choice-memory (glutamate) system, located in the prefrontal cortex. This temporary disruption is believed to be responsible for the addict's inability to accurately evaluate and stop their acting out behaviours, despite their awareness of negative consequences.
Underlying physical and psychiatric disorders. In some cases of sexual addiction, underlying disorders including depression, OCD, Bipolar Mood Disorder, ADD/ADHD, Asperger's Syndrome, epilepsy, or medication such as dopamine agonists designed to manage Parkinson's disease, may influence sexual behaviour.
Sex Addiction Australia recommends to seek advise from a qualified medical health professional, if characteristics of behaviour suggest an underlying primary condition.
