The Brain And Dependency

Addictive Substances And The Diversity In The Brain

The brain is physically altered over time from using addictive substances. Drug use is prioritized over everything else because of the alterations that happen in the brain when an addiction forms.


Negative effects of substance abuse are ignored once a dependency is developed since that person's brain is completely rewired. Even though physical signs of a dependence will perish, scenarios or feelings connected to previous substance misuse can bring addictions years down the line. This doesn't totally imply recovery isn't in reach. Treatment is a continuous process and people in recovery have to realize this. In recent time, there is a significant changes in the way addicts are helped to break free from it. If you or an individual you love is fighting to defeat dependence, acquire aid straight away.


How Addictions Happen

Every action we take - voluntary or involuntary - is controlled by the complex human brain. The brain is in charge of general motor movement, rates for the heart and breathing, character and ability to make decision. The limbic system puts out chemicals that elevate the mood of the user when an addictive substance is taken. Continuous drug abuse is the consequence of this. 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.

Triggering The Brain Reward System

The brain reward system is activated by the abuse of habit forming substances. Often activating of this system with substances can lead to dependence. The limbic system is automatically set off whenever we engage in pleasurable activities. This is all part of natural instincts for adopting and survival. Every time something sparks off this system, the brain supposes something essential to survival is taking place. We experience satisfaction and elation when the brain now pays us for that.


For instance, we drink water again because the reward system is switched on each time we are thirsty and quench that thirst with water. Dependent substances hijack this system, leading to emotions of joy for activities that are really dangerous. The brain reward system is more strongly affected by addictive substances.


Dependency Biochemistry

Dopamine has a critical function in the reward system. Dopamine sends signals to the reward system and is a naturally produced chemical in the brain. Drugs can either act like dopamine or lead to an increase in dopamine in the brain when they are introduced to the limbic system.

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. Essentially, the reward system is taken hostage by the drug.

The result is craving the substances that will bring dopamine levels back to normal. An individual in this condition is no longer in a position of feeling good without the substance.


Neurofeedback And Addiction

A method of addiction treatment getting popularity is neurofeedback. Electroencephalogram (EEG) Biofeedback is another name for it. Neurofeedback is a brain coaching procedure that greatly aids the brain to adapt to perform better. Sensors are applied to the scalp by the person performing the therapy that monitor brain activity during this process. The leader then rewards the brain for diverting its own action to better, very healthy trends.

Underlying problems that might be activating addiction are targeted by neurofeedback and these problems are:

  • Dejected
  • Panicking
  • Trauma
  • Inability to sleep

Neurofeedback has shown that it is a great treatment for drug dependency with numerous patients by helping the brain comprehend how to function without drugs. This is included in the program of some rehab centres. If you need assistance, contact us on 0800 246 1509 and we will find one for you.
