Dependency And The Brain what-is-addiction

Addictive Drugs And Alterations In The Brain

After the prolonged use, these drugs can alter the brain. 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 therapy is a never-ending process for addicts in recovery and they must understand that. 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 Come About

Everything we do, both consciously or unconsciously, are controlled by the brain. The brain fully controls normal motor skills, heart and breathing levels, feelings, behaviour and decision-making. The limbic system sets chemicals free once a user takes an addictive drug in order to make the person feel pleasure. Using too much of an addictive drugs then becomes a second nature. The extreme, uncontrolled desire to use the substance, despite its negative effects, is caused by the changes that have happened in the limbic system. The most important thing is now the desire to take the drug.


The brain also has a section that controls dependency. The limbic system is the name of that section in the brain. It causes us to feel elated and is also called "brain reward system".

Setting Off The Brain Reward System

The ill-use of addictive drugs sparks off the brain reward system. Activating the reward system on a frequent basis can cause addiction. 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. We experience satisfaction and elation when the brain now pays us for that.


For instance, when you quench your thirst by drinking water, the reward system is activated, hence we do this again and again. Even when we engage in dangerous activities, we still feel some satisfaction because these drugs and alcohol have taken over the reward system. Sadly, the effects on the brain reward system are far much potent from addictive substances.


Addiction Biochemistry

A necessary role in the reward system is dopamine. Dopamine sends signals to the reward system and is a naturally produced chemical in the brain. 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.

Drugs utilize floods neuroreceptors with dopamine. The "high" that comes with substance abuse is the consequence. The brain is no longer naturally able to make normal levels of dopamine after continues abuse. In reality, substances take the reward system hostage.

This causes the brain to crave the substance in order to get dopamine back to normal levels. Someone in this position can no longer feel normal without the substance.


Neurofeedback In Dependency

A method of addiction treatment getting popularity is neurofeedback. It is as well referred to as Electroencephalogram (ECM) Biofeedback. Neurofeedback is a training session for the brain to improve its functionality. In this process, sensors are placed on the patient's scalp by the therapy administrator to monitor brain activities. The leader then rewards the brain for diverting its own action to better, very healthy trends.
