Around the globe, a massive amount of health and economic distress is caused by substance and alcohol use disorders. Addiction to substances can be an obstacle for the individual, family and society as a whole. The process of addiction may often start as just a single puff or something to relax oneself, but can end up being life-threatening as well.
The neuroscience of addiction focuses on how addiction affects the brain. It majorly helps in understanding the changes in reward pathways in the brain because of addiction. The rewiring of the brain happens because of consistent use of a substance.
Introduction: Why Addiction Is a Brain Disease
If you think that the sole reason behind addiction is a lack of willpower, then this paragraph will encourage you to rethink that! Researchers focus on the structural and functional changes in the brain that also influence addiction and the recovery journey. These changes can further impact an individual’s cognitive abilities, such as problem solving, decision making and impulse control. Genetics can also influence the vulnerability of an individual towards becoming more prone towards addiction.
This addiction and the brain are related concepts, and one should seek professional support for the treatment process.
The Neuroscience of Addiction
While the neuroscience of addiction is highly detailed and comprehensive, a gist of the same has been given below:
- If a substance is consumed, the brain’s reward system is affected.
- Drugs can also influence the normal brain communication process.
- Due to the intensity of drugs, the other rewarding elements do not feel so pleasurable.
- The process of memory and learning reinforces an individual to again consume the substance for the same effect.
- Gradually, tolerance and dependence on the drug can be built due to persistent use.
- The amount of substance needed to feel pleasure may also increase due to tolerance.
- Addiction can develop due to all of these neural changes in the brain.
Dopamine and Addiction: The Brain’s Chemical Messenger
Dopamine is a neurotransmitter that is often associated with reward and pleasure. Dopamine is also associated with motivation and behaviour that is goal-directed. Dopamine can also contribute to learning behaviour through reward association.
For example, if an individual engages in a behaviour and dopamine is secreted in the brain, then a sense of pleasure is experienced. This pleasure acts as a reward, and the individual might want to engage in the behaviour repeatedly for the same experience.
How Drugs Cause Dopamine Surges
Substance intake often leads to excess dopamine production in the brain. This is much more than the naturally rewarding acts and food items. Some drugs can increase dopamine production, while others may block dopamine reuptake by neurons. In both situations, an excess of dopamine can lead to a sense of ‘euphoria’. As the brain learns the association between substance and pleasure, natural rewards can feel less appealing, leading to increased desire for the substance. Thus, an individual may begin to prioritize drug seeking behaviour, and compulsive drug use can be observed.
Dopamine Imbalance and Cravings
Here are the ways in which dopamine imbalance and craving impact one’s functioning:
- Repeated drug use can influence natural dopamine production.
- The daily activities may not feel rewarding, leading to a lack of motivation.
- One might feel a craving for high dopamine levels and to experience pleasure.
- Withdrawal from the drug can also lead to intense irritability due to dopamine craving.
- Dopamine imbalance may also become a reason for relapse.
Due to all these reasons, dopamine and addiction are a central part of the neuroscience of addiction.
How Addiction Affects the Brain Over Time
Here is how addiction affects the brain:
- Long-term use of substances and drugs can lead to changes in brain structure.
- Habit-forming circuit can get strengthened in a way that one becomes habituated to substance consumption.
- Memory and learning function can be impacted because of drug intake.
- Emotional instability can be caused, wherein the individual may experience mood swings frequently.
- Dependence on substances and withdrawal symptoms may also be observed.
Why Addiction Makes Quitting So Difficult
You might have heard several people sharing about wanting to quit, but only some can do so successfully. Addiction can make quitting difficult because:
- The changes in brain functioning influence reward pathways
- Cravings and withdrawal symptoms can be difficult to manage
- Environmental triggers can also lead to relapse
- Stress can increase the urge of learnt behaviour of substance consumption
- One may not feel the same pleasure from other daily activities
The Role of Professional Addiction Treatment
Walking on the addiction recovery journey on one’s own can be emotionally taxing and difficult. One may not understand the root cause of addiction and efforts to quit may fail, making one feel even more demotivated. That is why a professional who is an expert in addiction and the brain can guide you in the treatment process. The support that an expert can offer includes:
