Changes In The Brain Because Of Addictive Substances

The brain is physically altered over time from using addictive substances. Addicts will place the drug above anything else.


Regardless of the outcome, an addict's brain is altered to crave for the drug. Cravings for the substance can occur even after a lot of time has passed because any feelings or situations connected to the previous drug abuse can cause them, even though physical effects of a dependency are no longer present. Rehabilitation is, however, still possible. Recovering from the addiction requires continuous effort, something addicts at rehab centres should know. Dependence therapy is growing each day and has quickly bettered over the past years. Seek the assistance of others if you or your loved one is fighting the problem.


How Addictions Happen

Every action we take - voluntary or involuntary - is controlled by the complex human brain. The brain fully controls normal motor skills, heart and breathing levels, feelings, behaviour and decision-making. The limbic system is responsible for the control making people experience a strange feeling of happiness when on drugs. Using too much of an addictive drugs then becomes a second nature. The highly intense, involuntary desire to utilize a drug - no matter the damage it may bring - is as a result of the real alterations that have taken place in the brain reward system. The most important thing is now the desire to take the drug.


Dependence on drugs is controlled by a section of the brain. The name of this section of the brain is known as the limbic system. It causes us to feel elated and is also called "brain reward system".

Stimulating The Reward System Of The Brain

The brain's reward system is triggered when a person uses an addictive drug. An addiction can occur when this system is habitually activated with drug use. The limbic system is automatically set off whenever we engage in pleasurable activities. It is part and parcel of our natural capability to get used to and survive. When this system is activated, the brain assumes that whatever is occurring is necessary for survival. We experience satisfaction and elation when the brain now pays us for that.


For instance, we trigger the rewards system every time we drink water when we are feeling thirsty so we can keep performing that action again and again. This system is manipulated by addictive substances, causing things that are actually harmful to us to cause feelings of pleasure. Sadly, the effects on the brain reward system are far much potent from addictive substances.


Dependency And The Biochemistry

One of the most significant parts of the reward system is dopamine. It communicates with the limbic system because it resides in the brain. When bought in the limbic system, substances either copy dopamine or lead to an excess creation of it in the brain.

Normal activities that set off the limbic system, like eating, drinking, making love, music etc., do not adjust the brain for addiction since they release usual amounts of dopamine.

Regular levels of dopamine triggered by normal actions are 10 times lower than levels released with the use of addictive drugs.

Dopamine is usually combined with floods neuroreceptors by drugs. This is what leads to the "high" that is brought on with drug use. After prolonged substance ill-use, the human brain is not in a position to naturally create usual levels of dopamine. In reality, substances take the reward system hostage.

The result is craving the substances that will bring dopamine levels back to normal. Not taking the drug automatically leads to despondency for such addicts.


Addiction And Neurofeedback

The brain is trained to be able to work better with the neurofeedback process. In this process, sensors are placed on the patient's scalp by the therapy administrator to monitor brain activities. When the brain activity changes to positive, healthier pattern, the administrator rewards the brain.
