Dependency And The Brain what-is-addiction

Changes In The Brain Because Of Addictive Substances

The brain is affected and modified after a certain period of addictive drugs abuse. When dependence grows, alterations in the brain make exploiters place substance above everything 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. This however does not make recovery an impossibility Recovering from the addiction requires continuous effort, something addicts at rehab centres should know. Treatment for addiction is evolving every day and has steadily become better over the years. Should you or someone you love be battling an addiction, seek help soon.


How Do Addictions Develop

Every voluntary and involuntary choice we make is controlled by a complex organ in the body, the human brain. The brain is in charge of general motor movement, rates for the heart and breathing, character and ability to make decision. When a user takes addictive substances, the brain reward system produces a chemical that makes the user feel good This promotes habitual drug misuse. The extreme, uncontrolled desire to use the substance, despite its negative effects, is caused by the changes that have happened in the limbic system. Sustaining the addiction usually takes priority.


The brain has a part that is accountable for addiction. Limbic system is responsible for this. 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 misuse of addictive drugs sets off the reward system of the brain. Activating the reward system on a frequent basis can cause addiction. The limbic system is automatically set off whenever we engage in pleasurable activities. Our survival and changing according to events depend on it. Anytime this system is activated, the brain concludes that an activity requiring survival is taking place. This behaviour is then rewarded by the brain by feelings of happiness.


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. 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.


The Biochemistry Of Dependency

One of the greatest influencers 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.

The reason usual activities that spark off the brain reward system (drinking, food, music, sex, and many more) don't reprogram the brain for dependence is due to the production of normal rates of dopamine.

The dopamine released by addictive substances can be up to 10 times more than the amount released from normal actions.

Substance use overloads neuroreceptors with dopamine. This makes one feel "high", similar to when you take drugs. After a prolonged addiction, the human brain cannot produce normal amounts of dopamine naturally. Basically, the reward system is under the arrest by drugs.

This causes the brain to crave the substance in order to get dopamine back to normal levels. Someone in such a situation cannot have feelings of pleasure without using the substance.


Neurofeedback And Addiction

Neurofeedback is gradually becoming one of the best cure for drug reliance. It is also known as Electroencephalogram (EEG) Biofeedback. Neurofeedback trains the brain to learn to function better. The therapy controller is supervising the brain activity while this process is being done by using sensors on the scalp. With this, the brain can improve its performance and make it better, the brain is then rewarded for doing that.

Neurofeedback supports to aim the essential effects that may be causing dependence, like

  • Dejected
  • Unnecessary worries
  • Being traumatized
  • Insomnia

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. Neurofeedback is often a part of a complete treatment plan by some treatment facilities. Contact us immediately on 0800 772 3971 to be linked with a treatment base that can support you well.
