In a person who becomes addicted, brain receptors are overwhelmed. The brain responds by producing less dopamine or by eliminating dopamine receptors, an adaptation similar to lowering the volume of a speaker when the noise becomes too loud.
Addiction
is a complex chronic disease that affects the brain and occurs due to many different underlying causes. 1 Scientific research around the world continues to identify several risk factors, such as genetics and the environment, that contribute to the development of addiction.However, the causes of addiction are not yet fully understood, 15. An addictive personality is a personality who is more likely to become addicted to something. This can include someone becoming extremely passionate about something and developing an obsession or fixation. The underlying factors for letting go and devoting too much to video games, food, sex, or drugs stem from hidden anxiety, depression, and poor impulse control. Genetics isn't the only indicator of addictive personalities; however, they can have a big influence on a person's personality traits.
The term “addictive personality” should be permanently removed from use in the field of alcohol and drug treatment (ODA). While the term is quite popular, the concept itself is controversial and there is a lack of consistent evidence to support the existence of an addictive personality. Genetic factors can play an important role in determining susceptibility to addiction, but other variables, such as family history, education, environment, socioeconomic status, and drug availability, also influence a person's risk of addiction. While research has not supported the existence of an addictive personality, researchers know that there are a number of factors unrelated to personality that increase the risk of developing an addiction.
A person's environment, or the people, places, and things they're exposed to can also influence whether they develop an addiction. Addiction, also known as substance use disorder (SUD), is a recurrent disorder that involves compulsive drug or alcohol use, which means that the person cannot reduce or stop smoking, even when it negatively affects a person's life. An addictive personality is a hypothetical set of personality traits that can make a person more susceptible to addiction. Critics argue that the idea of an addictive personality is harmful because it can cause people to underestimate their risk, contribute to stereotypes, and make people feel less empowered when dealing with addictions.
Research has discovered a link between genetics and a person's ability to have an addictive personality. So why do some people become addicted when others don't? Ultimately, the answer lies in a person's unique brain chemistry and lived experiences. Experiencing mental conditions such as depression and anxiety may, but not always, indicate addictive personalities. Although everyone's path to addiction is different, whether they try a drug or behavior, because that's what that person's parents or peers do, or just out of curiosity, what's common in all substance and behavioral addictions is their amazing ability to increase levels of a chemical substance important in the brain.
called dopamine, Boyle told Live Science. But unlike the way doctors can predict a person's breast cancer risk by looking for mutations in a given gene, no one knows enough to be able to identify any gene or predict the likelihood of inheriting traits that could lead to addiction, he said. .
