Addictive Substances And Adjustments In The Brain

Addictive drugs normally alter the brain over a certain period. As the addiction increases, effects on the brain makes users choose drug use over other things.


Regardless of the outcome, an addict's brain is altered to crave for the drug. After several years, the desire to use the drug again may manifest itself due to some memories from the past after the effects on the body are gone. Rehabilitation is, however, still possible. But patients should understand that treatment is a continuous process. In recent time, there is a significant changes in the way addicts are helped to break free from it. Should you or someone you love be battling an addiction, seek help soon.


How Addictions Evolve

The human brain is an intricate organ managing all willing and unwilling step we embrace. Our attitude, breathing, how we think and decide on issues, and other important skills are dictated by the brain. The limbic system sets chemicals free once a user takes an addictive drug in order to make the person feel pleasure. Continuous drug abuse is the consequence of this. 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. Sustaining the addiction usually takes priority.


There is a section in the brain charged with addiction. This section of the brain is known as the limbic system. It is also known as "brain reward system" and it has a job to create feelings of enjoyment.

Igniting The Brain Reward System

The brain reward system is called to action when a drug is used. Dependence on drugs occur when the reward system is constantly called to action. When a person does something good for his or her wellbeing, it naturally triggers the brain reward system. Our survival and changing according to events depend on it. So, the brain thinks that something significant for the survival is occurring every time something triggers this system. The brain then honours that that character by developing feeling of pleasure.


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. Sadly, the effects on the brain reward system are far much potent from addictive substances.


Addiction Biochemistry

Dopamine performs a very crucial role in the reward system. Dopamine is a natural element in the brain which releases signals to the reward system. When presented into the reward system, substances sometime ape dopamine or lead to an excessive production of it inside 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.

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. The intoxicating effect of alcohol and drugs is caused by the combination. Producing the regular amount of dopamine needed by the body becomes difficult for the brain when drug is used for a long time. Typically, the drugs hijack the reward system.

The effects are a deep desire to take the drug to normalize the dopamine amounts. Someone in such a situation cannot have feelings of pleasure without using the substance.


Neurofeedback During Addiction

Neurofeedback is one of the most effective treatments for dependency. Electroencephalogram (EEG) Biofeedback is another name for it. 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. The leader then rewards the brain for diverting its own action to better, very healthy trends.

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

  • Depression
  • Apprehension
  • Upheaval
  • Sleeplessness

By supporting the brain to readapt how to be without substances, neurofeedback has shown to be a really victorious dependence treatment for a good number of people. Neurofeedback is often a part of a complete treatment plan by some treatment facilities. If you need assistance, contact us on 0800 246 1509 and we will find one for you.
