Sumary of Predisposition to addiction may be genetic, study finds:
- People who have a high sensation-seeking personality trait may be more likely to develop an addiction to cocaine, according to a Rutgers study..
- said lead author Morgan James, a member of the Rutgers Brain Health Institute and an assistant professor in the department of psychiatry at Rutgers Robert Wood Johnson Medical School..
- “The interaction found between sensation-seeking traits and the drug-taking experience show that predisposition to addiction has a genetic basis, and that this interacts with environmental factors such as patterns of drug use..
- The sensation-seeking trait was predictive of rats’ likelihood to exhibit stronger motivation for drugs when we gave them the opportunity to take cocaine.”.
- The lab study found that high sensation-seeking rats — those with a strong desire for new experiences and a willingness to take risks to be stimulated — were more prone to developing behavior that reflects human addiction..
- The findings suggest that high sensation-seeking people have a greater risk of losing control over their drug intake, which makes them more vulnerable to drug addiction….
