Ways Individuality Increases Threat of Drug Abuse

People with certain personality traits may in increased risk for medication use problems, and studying personality can help experts better understand and deal with these nagging problems, according to a new review.
But they’ve largely failed to do so, though the condition can run in families even, said Dr. Sergi Ferré, a senior scientist and section chief at the National Institute on Drug Abuse.
That may be since the connection between genes and substance use is not straightforward, and character traitsmay serve as a bridge between your two, Ferré said. Character traits have been linked with the chance of having substance use disorder currently, and with specific circuits in the mind.
“We should [have] a lot more studies trying to connect those personality characteristics and genes,” Ferré stated. ” Ferré said, referring to substance use disorder.
Once researchers understand, from a human brain perspective, as to why people develop drug make use of problems, they may be able to develop drug treatments that reverse these effects, the researchers said.
Risky personalities
For example, people with introverted personalities, and who generally have fewer positive emotions, or be attracted to rewards in existence, will abuse drugs, according to the new review. On the other hand, extroverted people who have even more positive emotions are less inclined to abuse drugs.
Winning a game, or obtaining a promotion – and these additional benefits “compete” with the positive feelings that can include using a drug, Ferré said. However, people with low positive emotionality/extroversion possess less interest in other benefits, and are easier pulled in by the consequences of the drug, Ferré said.
A second personality trait linked with substance abuse is negative emotionality/neuroticism, or the tendency to experience negative feelings, such as for example anxiety and depressed feeling, and respond poorly to stressors. People with substance make use of disorder, and other mental health disorders, have high degrees of this character trait often.
In drugs, something that allows them to escape,” Ferré said.
Finally, low degrees of a trait referred to as constraint, which is the capability to stop a behavior or action once you start it, is also linked with an increased risk of substance abuse.
not just their genes and personality, but also their environment and past drug use.
Better treatments
Several brain circuits have been associated with the personality traits that individuals who develop drug problems generally have. For example, people who have low degrees of positive emotions have got fewer receptors for the mind chemical dopamine, which would describe the tendency of medication users to have small interest in benefits besides drugs.
People may be born with fewer dopamine receptors than others, but drug use may also lower their numbers, possibly affecting character and making people less extroverted, in addition to increasing the chance for drug abuse.
“Drugs, they transformation our personality, unfortunately in the direction in making us more susceptible to SUD,” Ferré said.
A better understanding of the brain circuits linked with these risky personality characteristics, as well as the genes that control the brain circuits, may lead to new treatments for medication users.
“Understanding the brain systems that determine these personality traits allows us to work on these systems pharmacologically and transformation them in the direction that make a person more resilient,” so they can resist drug abuse, Ferré said.
Ferré and colleagues recently reviewed the link between personality traits and substance use disorder in the April issue of the journal Developments in Cognitive Sciences.
