How the Brain Changes through Drug Addiction
You can identify an addict when you see someone who has an intense need for the source of an addiction to the point that living revolves around that drug. A victim of addiction no longer has any control over substance abuse and will do anything to get more, regardless of the consequences. All of these behaviors are due to changes that have taken place in the brain. It begins with how the brain registers the feeling of pleasure. Dopamine is a neurotransmitter that is released in the brain when positive feelings are experienced. It makes a person feel good, and that is the key to addiction. Drugs cause a surge of dopamine to be released, providing intense pleasure. Through repeated use of a drug, the brain is trained to like the drug and want more of it until it becomes a need to feel those same chemicals.
The Psychosis of Addiction
As the brain becomes altered through addiction, psychosis is common as well. Those who are under the influence of any form of drug over a prolonged period of time may experience a gamut of psychological issues. Changes in personality, intense anxiety, the inability to focus, and gaps in memory are par for the course for victims of addiction. When the brain is changed in anyway, it will be exhibited through behaviors and alterations in thought processes. In order to address these problems with addiction, it is necessary to get professional help in a medical facility. Drug rehab assists an individual in breaking free from the source of addiction and retraining the brain to function normally once again.
Changes in the brain pull victims of addiction back in for more abuse time after time. It is important to understand that substance abuse is beyond the control of the individual. Drug rehab can establish new patterns in the brain and assist an addict in finding the path to sobriety once again. It is therefore advisable not to indulge in drugs in the first place because it is very dangerous and could lead to mental deterioration.
