The Biology of Gambling Addiction
All addictions have a biological aspect, and gambling is no different. Process addictions like these cause changes in the brain, which can be observed. Understanding how these processes affect the brain can be instrumental in gambling addiction treatment.
The main culprit, in this instance, is dopamine. Dopamine is a neurotransmitter (a chemical in our brain) involved in feelings of pleasure, reward, and motivation. Naturally, dopamine is released when we accomplish something that is beneficial for our longevity and survival: after having sex, completing an exercise routine, eating a healthy meal, or other similar things.
In the world where we live, our longevity and survival are often governed by our financial status. We need money to clothe and feed ourselves, maintain our homes, and take care of our family. For this reason, the brain is wired to release a tremendous amount of dopamine when we are presented with the opportunity to obtain large sums of money – such as during a gambling session.
The dopamine release that occurs during a gambling session occurs in a part of the brain known as the reward pathway. Unfortunately, consistent activation of this pathway happens when compulsive gambling leads to a dopamine insensitivity, one of the most devious signs of gambling addiction.
It means that people tend to require more and more stimulation to release the same amount of dopamine and receive the same amount of pleasure that they originally felt when first winning a bet. It occurs in much the same way that a drug addict requires higher and higher doses of their choice drug to experience the same enjoyment.
This is also one of the reasons why not everyone understands how to stop gambling addiction. It’s not a simple matter of ‘stopping gambling.’ As a person gambles more and more, their brain becomes reliant on the risk and reward of gambling to release its pleasure chemicals. It means that when a person is unable to gamble, they will be physically unable to produce the dopamine that they need to feel good.
It is the main reason that people go through a psychological period of ‘gambling withdrawal.’ Rebuilding and restoring the dopamine system can take weeks, months, or years, and during this period, it can be extremely tempting for someone to return to the casino. This is one of the most significant reasons to seek gambling addiction help.
