Drug seeking and cravings to the brain: Addictions effect on the brain’s reward system

Drug seeking and cravings to the brain. Ideally drugs are a serious threat to your health and the brain is one of the organs affected the most.

Drug seeking and craving to the brain is very interesting more so when we consider how the brain functions. It is true that the brain has evolved over time in a way that ensures human survival. And in fact our brain’s reward system is part of that survival system. In many instances we often experience an urgent need for food whenever we are starving and generally have a powerful desire for sex too. According to doctor Dalal Akoury MD and founder of AWAREmed Health and Wellness Resource Center, the brain’s reward system rewards food and sex because they ensure our survival. Unfortunately, drugs of abuse operate within these reward systems which leads people to experience an urgent need or powerful desire for drugs or addictive activities.

The brain’s reward system has ensured our species survival. You may have not known but food, water, and sex are some of the elements that activate the reward system. Therefore when the brain’s reward center is activated, it releases dopamine. Dopamine then creates a pleasing, enjoyable sensation which then motivates us into repeating these behaviors which are necessary for our survival. The reason why this is happening is because dopamine has rewarded us with a pleasurable feeling. Doctor Akoury recommends that from an evolutionary standpoint of view, it is very helpful to have a reward system that works. Like for instance, imagine that there is very little food and you’re wandering about looking for food. When you finally find something to eat, this triggers your reward system. This pleasing feeling (dopamine “reward”) will become associated with whatever behavior that led you to that food. This causes you to want to repeat that behavior. Moreover, the reward system is closely tied to emotional and subjective memories. If you were successful and found food in a particular place for instance, in the future you will want to look for food in the same location. This reward system increases the likelihood that you will be successful in finding food there the next time. This is because your brain chemicals are rewarding you with a pleasing sensation. It also helps you to remember how and where this pleasant feeling occurred.

Drug seeking and cravings to the brain: The negative dopamine reward sensation

It will come to you as a surprise that the element that motives your survival is unfortunately the very same reward system that ensures your survival also rewards drug use. Doctor Akoury says that all addictive substances and activities will trigger the release of dopamine which rewards us with a pleasant sensation thereby succeeding in motivating us to continuously indulge in these harmful behaviors. It is nowadays common knowledge that peoples with addiction problems will all it takes to get their drug of choice and in the same way, they continue with their addiction despite the harm it causes to themselves or their loved ones. It is therefore very important to note that all these characteristic of addictive behaviors arise from the brain’s pleasure and rewards centers. Therefore seeking for lasting solutions becomes a must to do for all victims. This may not be a very popular thing owing to the addictiveness of some of these drugs, but nonetheless it is the best option if you want to have a healthy life that is free from all sorts of addiction.

Drug seeking and cravings to the brain: Mesolimbic pathway

We now have a basic understanding of the purpose and functioning of the brain’s reward system. Let’s interrogate it a little bit further. The circuit most associated with pleasure and reward is the mesolimbic pathway which is located in the brainstem. The objective of this area of the brain is primarily concerned with basic survival. Within the mesolimbic pathway is an area called the ventral tegmental area (VTA). The VTA projects to the nucleus accumbens (thought to be the reward center). The neurotransmitter most commonly linked with the mesolimbic system is dopamine. Many people consider dopamine to be the driving force behind the human pursuit of pleasure. The release of dopamine is a pleasurable sensation. The release of dopamine motivates us to repeat behaviors or activities that prompted this release. This system’s purpose was to promote survival by rewarding life sustaining behaviors such eating and procreation.

All addictive drugs and activities release varying amounts of dopamine into the nucleus accumbens with stimulant drugs like cocaine and methamphetamine releasing the most. However when it comes to drugs like alcohol or heroin, the brain’s own opiate system (endorphins) also gets involved. Doctor Akoury further says that even though different forms of addictions have different effects in the nucleus accumbens, they share one common denominator that they all activate the reward system which in turn motivates us to repeat those behaviors, even though they may be harmful. Besides what we have discussed about the concepts of reward, pleasure, and craving together, it is however very important to appreciate that there is a distinction between pleasure-seeking and drug seeking. Note that pleasure-seeking is all about the pleasurable, rewarding aspect of addiction while drug-seeking refer to the craving aspect of addiction. Dopamine may be more involved in drug-seeking (craving) component of addiction. The opiate (endorphin), GABA, or glutamatergic systems may be more involved in pleasure-seeking aspect of addiction too.

Pleasure-seeking and drug-seeking (cravings) are inter-related, yet distinct. Research has established that natural rewards (food, water, sex) typically lessen their influence on the reward system over time. As a behavior occurs more often, dopamine levels tend to decrease in the process. Psychologists call this habituation. This makes sense. Once you’ve eaten enough food, you don’t need to be rewarded for eating more food. Then you would be eating too much, or too much of one type of food. Therefore everyone needs to take heed of keeping the brain free from all attacks be it from substances or otherwise.
