Is addiction an illness or a choice? This question has been fiercely debated over the years. Proponents for the disease concept of addiction say there are clear physiological differences between addicts and non-addicts – including greater levels of impulsivity, over which addicts have little control. Others dismiss the idea that addiction is an illness – they claim that addicts always act of their own free will, including when they make impulsive decisions. New research published in March 2019 sheds some light on this question.
Researchers from Cambridge University’s Department of Psychiatry and Aarhus University in Denmark have found that young people at risk of addiction show marked differences in a key brain region. The study showed there is “a strong association between increased behavioural impulsivity in young adults and abnormalities in nerve cells in the putamen, a key brain region involved in addictive disorders.” [1]
In terms of addiction, the putamen is significant because it sends dopamine signals to other parts of the brain. Dopamine is a neurotransmitter that has a number of functions including its role in pleasure and reward, as well as effects on mood, attention and cognitive ability. The putamen also plays a role in mediating impulsivity.
