How genes and environment affect brain and behavior in substance use

Neurobehavioral pathways of polygenic and polyenvironmental effects on the onset and maintenance of substance involvement

['FUNDING_R01'] · WASHINGTON UNIVERSITY · NIH-11123251

This project looks at how our genes and surroundings shape brain development and behavior, influencing when and why people start and continue using substances, especially during teenage years and young adulthood.

What this research studies

This project aims to understand why some people develop problematic substance use, particularly during adolescence and young adulthood. Researchers believe that the way our brains mature, with certain areas developing faster than others, might make it harder to control impulses and emotions when tempting situations arise. We want to explore how both our genetic makeup and the environments we grow up in contribute to these brain and behavioral patterns. By understanding these connections, we hope to find better ways to prevent and treat substance use issues.

Who could benefit from this research

Good fit: Ideal candidates for future related studies might include adolescents and young adults who are at risk for or are currently experiencing substance involvement.

Not a fit: Patients whose substance use issues are not primarily linked to developmental brain maturation or polygenic/polyenvironmental factors may not directly benefit from this specific line of inquiry.

Why it matters

Potential benefit: If successful, this work could lead to more targeted prevention strategies and treatments for substance use disorders by identifying key genetic and environmental risk factors.

How similar studies have performed: While the specific combination of polygenic and polyenvironmental effects on neurobehavioral pathways is complex, previous research has shown the influence of both genetic and environmental factors on substance use risk.
