Addiction And The Brain

Addictive Substances And The Diversity In The Brain

The brain is physically altered over time from using addictive substances. When dependence grows, alterations in the brain make exploiters place substance above everything else.


When one becomes addicted, their brain is practically redesigned to depend on the drugs even with their effects. Even though physical signs of a dependence will perish, scenarios or feelings connected to previous substance misuse can bring addictions years down the line. Despite this, recovery is still possible. Recovering from the addiction requires continuous effort, something addicts at rehab centres should know. During the past years, dependency treatment is progressing constantly and quickly. Seek the assistance of others if you or your loved one is fighting the problem.


Development Of Addictions

Everything we do, both consciously or unconsciously, are controlled by the brain. Our attitude, breathing, how we think and decide on issues, and other important skills are dictated by the brain. The limbic system is responsible for the control making people experience a strange feeling of happiness when on drugs. This boosts the desire to continue using the substance. Thanks to specific modifications that the brain's rewards system has experienced, a person will, despite dangerous consequences, feel a severe, involuntary craving to use a drug. Fulfilling the addiction becomes the first priority.


Dependence on drugs is controlled by a section of the brain. This section of the brain is known as the limbic system. The system, as well referred to as the "brain reward system," is accountable for creating emotions of pleasure.

Stimulating The Reward System Of The Brain

The brain reward system is activated by the abuse of habit forming substances. Often activating of this system with substances can lead to dependence. When we engage in activities that are beneficial for us, the brain reward system will automatically become operational. It is an important factor in our survival and adaptation. When this system is activated, the brain assumes that whatever is occurring is necessary for survival. The brain then honours that that character by developing feeling of pleasure.


For instance, we drink water again because the reward system is switched on each time we are thirsty and quench that thirst with water. Addictive substances take over this system, bringing about emotions of pleasure, even for behaviour that is really risky. Regrettably, dependent drugs have a much bigger impact on the brain reward system.


Dependency And The Biochemistry

One of the most significant parts of the reward system is dopamine. Dopamine sends signals to the reward system and is a naturally produced chemical in the brain. When bought in the limbic system, substances either copy dopamine or lead to an excess creation of it in the brain.

Because the dopamine they produce is insignificant, regular activities like food, music, sex, and drinking, do not alter the brain and cause dependence although they can switch on the reward system.

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

Drugs utilize floods neuroreceptors with dopamine. The "high" that comes with substance abuse is the consequence. The human brain can't create regular dopamine levels normally after prolonged and constant substance abuse. In reality, substances take the reward system hostage.

Dopamine levels should go back to the original level, this triggers the desire for addictive substances. Users that find themselves in these situations have to use drugs in order to feel good.


Neurofeedback In Addiction

A method of addiction treatment getting popularity is neurofeedback. It is also referred to as (EEG)Electroencephalogram, Biofeedback. Neurofeedback is a training session for the brain to improve its functionality. Sensors are applied to the scalp by the person performing the therapy that monitor brain activity during this process. When the brain activity changes to positive, healthier pattern, the administrator rewards the brain.

Underlying issues that may be leading to addiction are targeted by neurofeedback, like:

  • Dejected
  • Panicking
  • Upheaval
  • Difficulty sleeping

People have found neurofeedback to be an effective recovery plan because it can assist the brain to adjust to life that is not built on drugs. This is included in the program of some rehab centres. Contact us now on 0800 246 1509 to get connected to a treatment facility that can assist you.
